IMMEDIATE RELEASE

GRAHAM CORPORATION REPORTS FOURTH QUARTER 2005 SALES INCREASE 37.5%

IMPROVING DEMAND DRIVEN BY THREE GLOBAL TRENDS:

      -     INCREASING NUMBER OF OIL REFINERIES

      -     ADDITION OF SYSTEMS TO TREAT HEAVY CRUDE OIL

      -     GROWING NUMBER OF PETROCHEMICAL PROCESSING PLANTS

DEMAND ALSO POSITIVELY IMPACTED BY EPA REGULATIONS FOR LOWER SULFUR
TRANSPORTATION FUEL

BATAVIA, NY, June 06, 2005 - Graham Corporation (AMEX: GHM), a global designer,
manufacturer, and supplier of ejectors, pumps, condensers, vacuum systems and
heat exchangers for the oil refining, petrochemical and power generation
industries, today reported results for the fourth quarter and fiscal year ended
March 31, 2005. Sales for the fourth quarter were up 37.5% to $13.2 million
compared with $9.6 million in the same period last year. Income from continuing
operations for the fourth quarter was $743 thousand compared with $140 thousand
in the same period last year. Diluted earnings per share from continuing
operations of $0.42 were up $0.34 compared with $0.08 from the prior year.

Sales were driven by the increasing global demand for oil and oil by-products.
This demand, coupled with higher prices on sweet crude oil, has caused
refineries and petrochemical plants to invest in new plants and upgrades of
existing plants around the world in order to use lower cost heavy sulfur crude
as their raw material source. Additionally, with Environmental Protection Agency
standards in the U.S. requiring lower sulfur content in transportation fuel
beginning in 2006, refineries are upgrading their processing facilities to
address improved sulfur reduction. Graham's global presence and its reputation
for providing quality, reliable engineered systems in these fields have driven
demand for its ejectors and condensers.

Gross margins for the quarter were 25%, up from 18.7% in the fourth quarter last
year, reflecting operating leverage on higher volume, increased prices and
improved product mix. Selling, general & administrative expenses remained flat
on an absolute basis at $1.8 million, but declined to 13% of sales in the fourth
quarter of 2005 compared with 19% in the fourth quarter of 2004. Operating
margins from continuing operations for the fourth quarter were 11%, an
improvement from a negative 0.8% in the fourth quarter of last year.

Bill Johnson, President and CEO of Graham Corporation commented, "Our growth in
sales for the fourth quarter reflects the overall increase in demand for
Graham's engineered products that has been growing over the last year and,
specifically, in the last half of fiscal 2005. Also during the year, we were
able to increase prices in order to better address rising material costs and
improve margins."

GRAHAM CORPORATION REPORTS FOURTH QUARTER 2005 SALES INCREASE 37.5%
JUNE 06, 2005

DISCONTINUED OPERATIONS

The Company announced on March 15, 2005 that the Board of Directors approved a
plan to dispose of its U.K. pump manufacturing operations. The loss associated
with the disposal is reflected in the consolidated statement of operations as a
discontinued operation. Prior reporting periods have been restated to reflect
the U.K. operations separately from continuing operations. When considering the
discontinued operations, the net loss for the fourth quarter was $2.3 million,
or a loss of $1.31 per diluted share.

Graham will continue to provide quality pumps and engineered vacuum pump systems
to its global customers, engineering procurement contractors and technology
licensors.

2005 REVIEW

For the fiscal year ended March 31, 2005, sales were $41.3 million, up from
$37.5 million for a 10% increase from the previous fiscal year. Higher revenue
for fiscal 2005 includes increased sales for ejectors and condensers to the oil
refining and petrochemical processing industries and higher demand for heat
transfer products. Gross margins for fiscal 2005 were 18% compared with 16% for
the previous year. Gross margins in the second half of 2005 were 24% compared
with 15% for the first half of the year reflecting improved product mix and
operating leverage.

Income from continuing operations for fiscal 2005 was $296 thousand or $0.17 per
diluted share. This compares with a loss of $832 thousand or $0.51 per diluted
share, for the year ended March 31, 2004. After recognition of the loss from
discontinued operations for its U.K. subsidiaries of $3,202 thousand, the
Company incurred a net loss for fiscal 2005 of $2,906 thousand, or $1.69 per
diluted share. This compares with a net loss of $1,161 thousand for the year
ended March 31, 2004, after recognition of the loss from U.K. discontinued
operations of $329 thousand.

Graham's long-term debt obligations at the end of fiscal 2005 were $44 thousand,
down from $93 thousand at the end of fiscal year 2004. Cash and cash equivalents
at year end were $724 thousand. Capital expenditures for the year were $224
thousand compared with $249 thousand in the previous year.

OUTLOOK

Orders received in the fourth quarter of fiscal 2005 were $13.3 million compared
with $10.3 million in the fourth quarter of 2004, a 29% increase. Fiscal year
2005 orders were $49.9 million, up 47% from the previous fiscal year.
Approximately one-quarter of the increase was attributed to improved demand for
condensers for petrochemical and refinery work. Approximately one-quarter of the
increase related to ejector systems for refinery of ultra-low sulfur diesel,
heavy crude feed stock and general capacity expansion projects. The remainder of
increased demand was spread across other traditional markets, such as power,
HVAC and general industrial. Domestic orders were up 49% and exports have
increased 46% over fiscal 2004.

As of March 31, 2005, backlog was $22.4 million compared with $13.5 million at
2004 fiscal year-end. Approximately 44% of the backlog can be attributed to
equipment for refinery work, 22% to petrochemical projects and 16% to power
generation projects. Approximately 37% of the backlog will be delivered to North
America, 32% to Asia and 11% to Middle Eastern markets. Profit margins on orders
in backlog have improved due to price increases and an improved product mix.

Bill Johnson further added, "Our global opportunities have significantly
improved. The convergence of a number of different economic drivers for our
primary industries around the world is creating excellent opportunities for
Graham for the immediate future. Our strategic development of a global sales
representative network and establishment of sales operations in the U.K.,
serving Europe and the Middle East, and in China, serving all of Asia, will
enable us to build Graham's customer base and expand our market share."

He went on to say, "We have more than sufficient manufacturing capacity to meet
the continued growth in demand. In 2006, we plan approximately $2.0 million in
capital expenditures of which a substantial portion will be directed to both
hardware and software for information management and engineering design systems.
Our objective is to increase our engineering capacity without increasing the
number of engineers on staff. Expanded engineering capacity will enable us to
readily address the increasing volume of inquiries we are receiving for the
Company's products."

Graham is considering the possible sale of 99,000 shares of stock held in
treasury to finance capital spending and general working capital needs in fiscal
2006, in addition to cash generated from operations.
