ITEM 5.  OTHER EVENTS

       The pro forma financial information described below is being provided

ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS

         (b) PRO FORMA FINANCIAL INFORMATION

     The following unaudited pro forma consolidated financial statement (the
"Unaudited Pro Forma Consolidated Financial Statement") is based on the
historical consolidated financial statements of Flowserve Corporation
("Flowserve") and Ingersoll-Dresser Pump Company ("IDP") adjusted to give effect
to Flowserve's acquisition of IDP. The statement has been prepared as if the
acquisition had occurred on January 1, 2000. Flowserve acquired IDP on August 8,
2000 and, accordingly, its historical financial statements include IDP results
of operations from the acquisition date, including purchase accounting
adjustments and financing costs.

    The transaction and the related adjustments are described in the
accompanying notes. The pro forma adjustments are based upon available
information and certain assumptions that we believe are reasonable. In our
opinion, all adjustments that are necessary to present fairly the pro forma data
have been made. The Unaudited Pro Forma Consolidated Financial Statement does
not purport to represent what our results of operations would actually have been
had the transactions in fact occurred on such date or to project our results of
operations for any future period or date. The Unaudited Pro Forma Consolidated
Financial Statement should be read in conjunction with the historical
consolidated financial statements of Flowserve and IDP as well as Management's
Discussion and Analysis included in the Company's Annual Report.

    The unaudited pro forma information with respect to the IDP acquisition is
based on the historical financial statements of Flowserve and IDP. The IDP
acquisition has been accounted for under the purchase method of accounting. The
total purchase price for the IDP acquisition has been allocated to the tangible
and identifiable intangible assets and liabilities of the acquired businesses
based upon our estimates of their fair value with the remainder allocated to
goodwill. The purchase price allocation for the IDP acquisition is preliminary
and further refinements are likely to be made based on the resolution of
remaining contingencies.

    The historical consolidated financial statements of Flowserve and IDP were
prepared in accordance with accounting principles generally accepted in the
United States.

       NOTES TO UNAUDITED PRO FORMA CONSOLIDATED STATEMENT OF OPERATIONS



NOTE 1: PRO FORMA ADJUSTMENTS


    The following pro forma adjustments have been applied to the accompanying
historical consolidated statements of operations of Flowserve and IDP to give
effect to the IDP acquisition and the financing transactions as if they had all
occurred on January 1, 2000.

(a)  Represents actuarially determined adjustment to retiree pension and
     post-retirement benefits expense for hourly and salaried personnel of IDP
     that, pursuant to the IDP purchase agreement, were retained by
     Ingersoll-Rand, IDP's predecessor parent, net of the pension benefits
     provided to IDP employees under the Flowserve plans.

(b)  Represents incremental increase in depreciation expense in cost of sales
     based on estimated fair market value of property, plant and equipment over
     estimated useful lives of 3 to 40 years.

     This adjustment is based on a preliminary allocation of the purchase price
     for the IDP acquisition. The final allocation of the purchase price is
     contingent upon valuations that have not been completed.

(c)  Represents incremental increase in amortization expense based on estimated
     fair value of other intangible assets acquired over their estimated useful
     lives of approximately 17 years.

(d)  Represents estimated rental expense for the Phillipsburg plant for
     Flowserve's planned usage prior to the shutdown of the facility, net of
     direct costs related to the facility historically incurred by IDP which are
     not incremental costs to Flowserve as the Phillipsburg plant was not
     acquired under the terms of the Agreement.

(e)  Represents the elimination of corporate overhead expenses allocated by
     Ingersoll-Rand to IDP. Pursuant to the IDP purchase agreement, this
     allocation was eliminated upon closing of the IDP acquisition on August 8,
     2000. Flowserve will assume and provide services with no significant
     incremental cost above what it cost Flowserve to provide such services
     prior to the acquisition for tax services, information technology support,
     pensions and benefits administration and other overhead costs.

(f)  Represents the elimination of expense recorded by IDP related to a phantom
     stock incentive plan that was eliminated upon consummation of the
     Acquisition. IDP personnel losing these previous incentives may be eligible
     to participate in Flowserve's established stock option incentive scheme,
     which generally does not result in any compensation charge.

(g)  Represents incremental increase in annual goodwill amortization based on
     $230.0 million of estimated goodwill over an estimated useful life of 40
     years related to the IDP acquisition.
