Note 1 - Summary of Significant Accounting Policies	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Note A – Summary of Significant Accounting Policies
	General Information and Basis of Presentation
	The Gorman-Rupp Company is a leading designer, manufacturer and international marketer of pumps and pump systems for use in diverse water, wastewater, construction, dewatering, industrial, petroleum, original equipment, agriculture, fire protection, heating, ventilating and air conditioning (HVAC), military and other liquid-handling applications.
	The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles and include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated. Earnings per share are calculated based on the weighted-average number of common shares outstanding.
	Cash Equivalents and Short-Term Investments
	The Company considers highly liquid instruments with maturities of 90 days or less to be cash equivalents. The Company periodically makes short-term investments for which cost approximates fair value. Short-term investments at December 31, 2014 and 2013 consist primarily of certificates of deposit and are classified as prepaid and other on the consolidated balance sheets.
	Accounts Receivable and Allowance for Doubtful Accounts
	Accounts receivable are stated at the historical carrying amount net of allowance for doubtful accounts. The Company maintains an allowance for doubtful accounts for estimated losses from the failure of its customers to make required payments for products delivered. The Company estimates this allowance based on knowledge of the financial condition of customers, review of historical receivables and reserve trends and other relevant information.
	Inventories
	Inventories are stated at the lower of cost or market. The costs for approximately 75% of inventories at December 31, 2014 and 76% of inventories at December 31, 2013 are determined using the last-in, first-out (LIFO) method, with the remainder determined using the first-in, first-out method (FIFO). Cost components include materials, inbound freight costs, labor and allocations of fixed and variable overheads on an absorption costing basis.
	Long-Lived Assets
	Property, plant and equipment are stated on the basis of cost. Repairs and maintenance costs are expensed as incurred. Depreciation for property, plant and equipment and amortization for finite-lived intangible assets are computed by the straight-line method over the estimated useful lives of the assets and are included in cost of products sold and selling, general and administrative expenses based on the use of the assets. Depreciation expense was $13.2 million, $12.4 million and $11.2 million during 2014, 2013 and 2012, respectively.
	Depreciation of property, plant and equipment is determined based on the following lives:
		(in years)
	Buildings		20-50
	Machinery and equipment		15-May
	Software		5-Mar
	Amortization of finite-lived intangible assets is determined based on the following lives:
		(in years)
	Technology and drawings		13-20
	Customer relationships		15-Sep
	Other intangibles		18-Feb
	Long-lived assets, except goodwill and indefinite-lived intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount may not be recovered through future net cash flows generated by the assets. Impairment losses may be recorded when the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amounts based on the excess of the carrying amounts over the estimated fair value of the assets.
	Goodwill and Indefinite-Lived Intangible Assets
	Goodwill and other indefinite-lived intangible assets are not amortized but are reviewed annually for impairment as of October 1 or whenever events or changes in circumstances indicate there may be a possible permanent loss of value using either a quantitative or qualitative analysis. The Company uses a market-based approach to estimate the fair value of our reporting units and performed a quantitative analysis using a discounted cash flow model and other valuation techniques, but may elect to perform a qualitative analysis.
	For 2014, the Company used a quantitative analysis for substantially all of its goodwill impairment testing under which the fair value for each reporting unit was estimated using a discounted cash flow model, which considered forecasted cash flows discounted at an estimated weighted-average cost of capital. The forecasted cash flows were based on the Company’s long-term operating plan and a terminal value was used to estimate the cash flows beyond the period covered by the operating plan. The weighted-average cost of capital is an estimate of the overall after-tax rate of return required by equity and debt market holders of a business enterprise. These analyses require the exercise of significant judgments, including judgments about appropriate discount rates, perpetual growth rates and the timing of expected future cash flows. Sensitivity analyses were performed around these assumptions in order to assess the reasonableness of the assumptions and the resulting estimated fair values. For 2014, based on the quantitative analysis, the fair values of the Company’s reporting units continue to exceed the respective carrying amounts.
	A qualitative analysis may be performed by assessing certain trends and factors, including projected market outlook and growth rates, forecasted and actual sales and operating profit margins, discount rates, industry data and other relevant qualitative factors. These trends and factors are compared to, and based on, the assumptions used in the most recent quantitative assessment.
	Indefinite-lived intangible assets primarily consist of trademarks and trade names. The fair value of these assets is determined using a royalty relief methodology similar to that employed when the associated assets were acquired, but using updated estimates of future sales, cash flows and profitability. For 2014 and 2013, the fair value of indefinite lived intangible assets exceeded their carrying value.
	For additional information about goodwill and other intangible assets, see Note H.
	Revenue Recognition
	The Company’s revenues from product sales are recognized when all of the following criteria are met: persuasive evidence of a sale arrangement exists, the price is fixed or determinable, product delivery has occurred or services have been rendered, there are no further obligations to customers and collectability is probable. Product delivery occurs when the risks and rewards of ownership and title pass, which normally occurs upon shipment to the customer.
	Concentration of Credit Risk
	The Company generally does not require collateral from its customers and has a very good collection history. There were no sales to a single customer that exceeded 10% of total net sales for the years ended December 31, 2014, 2013 or 2012.
	Shipping and Handling Costs
	The Company classifies all amounts billed to customers for shipping and handling as revenue and reflects related shipping and handling costs in cost of products sold.
	Advertising
	The Company expenses all advertising costs as incurred, which for the years ended December 31, 2014, 2013 and 2012 totaled $3.5 million, $3.4 million and $3.5 million, respectively.
	Product Warranties
	A liability is established for estimated future warranty and service claims based on historical claims experience and specific product failures. The Company expenses warranty costs directly to cost of products sold. Changes in the Company’s product warranty liability are:
		2014			2013			2012
	Balance at beginning of year	$	1,170		$	1,133		$	1,228
	Provision		1,607			1,220			1,394
	Claims		(1,611	)		(1,183	)		(1,489	)
	Balance at end of year	$	1,166		$	1,170		$	1,133
	Foreign Currency Translation
	Assets and liabilities of the Company’s operations outside the United States which are accounted for in a functional currency other than U.S. dollars are translated into U.S. dollars using year-end exchange rates. Revenues and expenses are translated at weighted-average exchange rates effective during the year. Foreign currency translation gains and losses are included as a component of accumulated other comprehensive loss within equity.
	Gains and losses resulting from foreign currency transactions, the amounts of which are not material, are included in net income.
	Fair Value
	The carrying value of cash and cash equivalents, accounts receivable, accounts payable and short-term debt approximates their fair value.
	Use of Estimates
	The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
	Reclassification
	Certain amounts for 2013 have been reclassified to conform to the 2014 presentation.
	New Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board issued ASU 2014-09, “Revenue from Contracts with Customers,” which supersedes most current revenue recognition guidance, including industry-specific guidance, and requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and is to be applied retrospectively, with early application not permitted. The Company currently does not expect the adoption of ASU 2014-09 to have a material impact on its consolidated financial statements.

	The Company has a valuation allowance as of December 31, 2014 of $336,000 against certain of its deferred tax assets. The comparable amount of valuation allowance at December 31, 2013 was $162,000. ASC 740 requires that a valuation allowance be recorded against deferred tax assets when it is more likely than not that some or all of a Company’s deferred tax assets will not be realized based on available positive and negative evidence.
	At December 31, 2014, total unrecognized tax benefits were $576,000. Of the total, $452,000 of unrecognized tax benefits, if ultimately recognized, would reduce the Company’s annual effective tax rate.
	A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

	The Company is subject to income taxes in the U.S. federal and various state, local and foreign jurisdictions. Income tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for the years before 2011. The Company has $55,000 of unrecognized tax benefits recorded for periods which the relevant statutes of limitations expire in the next 12 months.
	The Company has state tax credit carryforwards of $545,000 and $343,000 as of December 31, 2014 and 2013, respectively, set to expire between 2018 and 2025.
	The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense for all periods presented. The Company accrued approximately $99,000, $85,000 and $91,000 for the payment of interest and penalties at December 31, 2014, 2013 and 2012, respectively.
	The Company has not provided an estimate for any U.S. or additional foreign taxes on undistributed earnings of foreign subsidiaries that might be payable if these earnings were repatriated since the Company considers these amounts to be permanently invested. It is not practicable to estimate the additional income taxes and applicable withholding taxes that would be payable on remittance of such earnings.
	In September 2013, the Internal Revenue Service issued final regulations governing the income tax treatment of acquisitions, dispositions, and repairs of tangible property. Taxpayers are required to follow the new regulations in taxable years beginning on or after January 1, 2014. The impact of the regulations is not material to the Company’s consolidated financial statements.

Compensation and Retirement Disclosure [Abstract]
Pension and Other Postretirement Benefits Disclosure [Text Block]	Note G – Pensions and Other Postretirement Benefits
	The Company sponsors a defined benefit pension plan (“Plan”) covering certain domestic employees. Benefits are based on each covered employee’s years of service and compensation. The Plan is funded in conformity with the funding requirements of applicable U.S. regulations. The Plan was closed to new participants effective January 1, 2008. Employees hired after this date, in eligible locations, participate in an enhanced 401(k) plan instead of the defined benefit pension plan. Employees hired prior to this date continue to accrue benefits.
	Additionally, the Company sponsors defined contribution pension plans made available to all domestic and Canadian employees. Total contributions for the plans in 2014, 2013 and 2012 were $1.6 million, $1.3 million and $1.2 million, respectively.
	The Company also sponsors a non-contributory defined benefit health care plan that provides health benefits to certain domestic and Canadian retirees and their spouses. The Company funds the cost of these benefits as incurred. For measurement purposes, and based on maximum benefits as defined by the plan, a zero percent annual rate of increase in the per capita cost of covered health care benefits for retirees age 65 and over was assumed for 2014 and is expected to remain constant going forward. A 5% rate of increase for retirees under age 65 was assumed.
	The Company recognizes the obligations associated with its defined benefit pension plan and defined benefit health care plan in its consolidated financial statements. The following table presents the plans’ funded status as of the measurement date reconciled with amounts recognized in the Company’s consolidated balance sheets:

	During 2013 and 2012, the Company recorded settlement losses relating to retirees that received lump-sum distributions from the Company’s defined benefit pension plan totaling $4.2 million and $2.9 million, respectively. These charges were the result of lump-sum payments to retirees which exceeded the plan’s actuarial service and interest cost thresholds in each of 2013 and 2012. The cost threshold was not exceeded in 2014.
	The prior service cost is amortized on a straight-line basis over the average estimated remaining service period of active participants. The unrecognized actuarial gain or loss in excess of the greater of 10% of the benefit obligation or the market value of plan assets is also amortized on a straight-line basis over the average estimated remaining service period of active participants.

To enhance the Company’s efforts to mitigate the impact of the defined benefit pension plan on its financial statements, the Company has moved towards a liability driven investing model to more closely align assets with liabilities based on when the liabilities are expected to come due. Currently, based on 2014 funding levels, equities may comprise between 14% to 34% of the Plan’s market value. Fixed income investments may comprise between 60% to 80% of the Plan’s market value. Alternative investments may comprise between 0% to 12% of the Plan’s market value. Cash and cash equivalents (including all senior debt securities with less than one year to maturity) may comprise between 0% to 10% of the Plan’s market value.
Financial instruments included in pension plan assets are categorized into a fair value hierarchy of three levels, based on the degree of subjectivity inherent in the valuation methodology. Level 1 assets are based on unadjusted quoted prices in active markets that are accessible to the reporting entity at the measurement date for identical assets. Level 2 assets are valued at inputs other than quoted prices in active markets for identical assets that are observable either directly or indirectly for substantially the full term of the assets. Level 3 assets are valued based on unobservable inputs for the asset (i.e., supported by little or no market activity). These inputs include management’s own assessments about the assumptions that market participants would use in pricing assets (including assumptions about risk). The level in the fair value hierarchy within which the fair value measurement is classified is determined based on the lowest level input that is significant to the fair value measure in its entirety. All of the Plan’s assets are in level 1 or level 2 within the fair value hierarchy and the following table sets forth by asset class the Plan’s fair value of assets.
Plan fair value asset allocation by category:
2014		$		%

Contributions
Although not required to make pension contributions in 2015, the Company may elect to contribute $2.0 million to $4.0 million to its pension plan in 2015.
Expected future benefit payments
The following benefit payments are expected to be paid as follows based on actuarial calculations:
	2015			2016			2017			2018			2019		Thereafter
Pension	$	5,095		$	5,319		$	7,044		$	6,089		$	6,366	$	30,780
Postretirement		1,543			1,576			1,612			1,695			1,781		8,957
A one percentage point increase in the assumed health care trend rate would increase postretirement expense by approximately $201,000, changing the benefit obligation by approximately $2.2 million; while a one percentage point decrease in the assumed health care trend rate would decrease postretirement expense by approximately $185,000, changing the benefit obligation by approximately $1.9 million. The assumed trend rates for healthcare costs are a 5% increase per year for retirees prior to the age 65 and 0% for retirees post age 65.
A one percentage point change in the assumed rate of return on the defined benefit pension plan assets is estimated to have an approximate $679,000 effect on pension expense. Additionally, a one percentage point increase in the discount rate is estimated to have a $1.4 million decrease in pension expense, while a one percentage point decrease in the discount rate is estimated to have a $1.6 million increase in pension expense.

Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	General Information and Basis of Presentation
	The Gorman-Rupp Company is a leading designer, manufacturer and international marketer of pumps and pump systems for use in diverse water, wastewater, construction, dewatering, industrial, petroleum, original equipment, agriculture, fire protection, heating, ventilating and air conditioning (HVAC), military and other liquid-handling applications.
	The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles and include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated. Earnings per share are calculated based on the weighted-average number of common shares outstanding.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash Equivalents and Short-Term Investments
	The Company considers highly liquid instruments with maturities of 90 days or less to be cash equivalents. The Company periodically makes short-term investments for which cost approximates fair value. Short-term investments at December 31, 2014 and 2013 consist primarily of certificates of deposit and are classified as prepaid and other on the consolidated balance sheets.
Receivables, Policy [Policy Text Block]	Accounts Receivable and Allowance for Doubtful Accounts
	Accounts receivable are stated at the historical carrying amount net of allowance for doubtful accounts. The Company maintains an allowance for doubtful accounts for estimated losses from the failure of its customers to make required payments for products delivered. The Company estimates this allowance based on knowledge of the financial condition of customers, review of historical receivables and reserve trends and other relevant information.
Inventory, Policy [Policy Text Block]	Inventories
	Inventories are stated at the lower of cost or market. The costs for approximately 75% of inventories at December 31, 2014 and 76% of inventories at December 31, 2013 are determined using the last-in, first-out (LIFO) method, with the remainder determined using the first-in, first-out method (FIFO). Cost components include materials, inbound freight costs, labor and allocations of fixed and variable overheads on an absorption costing basis.
Property, Plant and Equipment, Policy [Policy Text Block]	Long-Lived Assets
	Property, plant and equipment are stated on the basis of cost. Repairs and maintenance costs are expensed as incurred. Depreciation for property, plant and equipment and amortization for finite-lived intangible assets are computed by the straight-line method over the estimated useful lives of the assets and are included in cost of products sold and selling, general and administrative expenses based on the use of the assets. Depreciation expense was $13.2 million, $12.4 million and $11.2 million during 2014, 2013 and 2012, respectively.
	Depreciation of property, plant and equipment is determined based on the following lives:
		(in years)
	Buildings		20-50
	Machinery and equipment		15-May
	Software		5-Mar
	Amortization of finite-lived intangible assets is determined based on the following lives:
		(in years)
	Technology and drawings		13-20
	Customer relationships		15-Sep
	Other intangibles		18-Feb
	Long-lived assets, except goodwill and indefinite-lived intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount may not be recovered through future net cash flows generated by the assets. Impairment losses may be recorded when the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amounts based on the excess of the carrying amounts over the estimated fair value of the assets.
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	Goodwill and Indefinite-Lived Intangible Assets
	Goodwill and other indefinite-lived intangible assets are not amortized but are reviewed annually for impairment as of October 1 or whenever events or changes in circumstances indicate there may be a possible permanent loss of value using either a quantitative or qualitative analysis. The Company uses a market-based approach to estimate the fair value of our reporting units and performed a quantitative analysis using a discounted cash flow model and other valuation techniques, but may elect to perform a qualitative analysis.
	For 2014, the Company used a quantitative analysis for substantially all of its goodwill impairment testing under which the fair value for each reporting unit was estimated using a discounted cash flow model, which considered forecasted cash flows discounted at an estimated weighted-average cost of capital. The forecasted cash flows were based on the Company’s long-term operating plan and a terminal value was used to estimate the cash flows beyond the period covered by the operating plan. The weighted-average cost of capital is an estimate of the overall after-tax rate of return required by equity and debt market holders of a business enterprise. These analyses require the exercise of significant judgments, including judgments about appropriate discount rates, perpetual growth rates and the timing of expected future cash flows. Sensitivity analyses were performed around these assumptions in order to assess the reasonableness of the assumptions and the resulting estimated fair values. For 2014, based on the quantitative analysis, the fair values of the Company’s reporting units continue to exceed the respective carrying amounts.
	A qualitative analysis may be performed by assessing certain trends and factors, including projected market outlook and growth rates, forecasted and actual sales and operating profit margins, discount rates, industry data and other relevant qualitative factors. These trends and factors are compared to, and based on, the assumptions used in the most recent quantitative assessment.
	Indefinite-lived intangible assets primarily consist of trademarks and trade names. The fair value of these assets is determined using a royalty relief methodology similar to that employed when the associated assets were acquired, but using updated estimates of future sales, cash flows and profitability. For 2014 and 2013, the fair value of indefinite lived intangible assets exceeded their carrying value.
	For additional information about goodwill and other intangible assets, see Note H.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition
	The Company’s revenues from product sales are recognized when all of the following criteria are met: persuasive evidence of a sale arrangement exists, the price is fixed or determinable, product delivery has occurred or services have been rendered, there are no further obligations to customers and collectability is probable. Product delivery occurs when the risks and rewards of ownership and title pass, which normally occurs upon shipment to the customer.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentration of Credit Risk
	The Company generally does not require collateral from its customers and has a very good collection history. There were no sales to a single customer that exceeded 10% of total net sales for the years ended December 31, 2014, 2013 or 2012.
Shipping and Handling Cost, Policy [Policy Text Block]	Shipping and Handling Costs
	The Company classifies all amounts billed to customers for shipping and handling as revenue and reflects related shipping and handling costs in cost of products sold.
Advertising Costs, Policy [Policy Text Block]	Advertising
	The Company expenses all advertising costs as incurred, which for the years ended December 31, 2014, 2013 and 2012 totaled $3.5 million, $3.4 million and $3.5 million, respectively.
Standard Product Warranty, Policy [Policy Text Block]	Product Warranties
	A liability is established for estimated future warranty and service claims based on historical claims experience and specific product failures. The Company expenses warranty costs directly to cost of products sold. Changes in the Company’s product warranty liability are:
		2014			2013			2012

	Provision		1,607			1,220			1,394
	Claims		(1,611	)		(1,183	)		(1,489	)
	Balance at end of year	$	1,166		$	1,170		$	1,133
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency Translation
	Assets and liabilities of the Company’s operations outside the United States which are accounted for in a functional currency other than U.S. dollars are translated into U.S. dollars using year-end exchange rates. Revenues and expenses are translated at weighted-average exchange rates effective during the year. Foreign currency translation gains and losses are included as a component of accumulated other comprehensive loss within equity.
	Gains and losses resulting from foreign currency transactions, the amounts of which are not material, are included in net income.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value
	The carrying value of cash and cash equivalents, accounts receivable, accounts payable and short-term debt approximates their fair value.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates
	The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
Reclassification, Policy [Policy Text Block]	Reclassification
	Certain amounts for 2013 have been reclassified to conform to the 2014 presentation.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board issued ASU 2014-09, “Revenue from Contracts with Customers,” which supersedes most current revenue recognition guidance, including industry-specific guidance, and requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and is to be applied retrospectively, with early application not permitted. The Company currently does not expect the adoption of ASU 2014-09 to have a material impact on its consolidated financial statements.
