(1)  This Registration Statement also covers the associated preferred stock
     purchase rights (the "Rights") issued pursuant to a Rights Agreement dated
     as of August 1, 1986, and amended as of August 1, 1996 and as of June 1,
     1998, between the Registrant and National City Bank, as Rights Agent. Prior
     to the occurrence of certain events, the Rights will not be exercisable or
     evidenced separately from the Registrant's Common Stock.

(2)  Estimated solely for purposes of calculating the registration fee required
     by Section 6(b) of the Securities Act of 1933 (the "Securities Act"), the
     proposed maximum aggregate offering price of the Registrant's Common Stock
     was calculated in accordance with Rule 457(c) and (h) under the Securities
     Act as the average of the high and low prices per share of the Registrant's
     Common Stock on June 23, 1998 as reported on the New York Stock Exchange,
     multiplied by 50,000, the number of shares of the Registrant's Common Stock
     to be offered or sold pursuant to the employee benefit plan described
     herein.

ITEM 3.  INCORPORATION OF DOCUMENTS BY REFERENCE

         Flowserve Corporation (the "Registrant") hereby incorporates by
reference into this Registration Statement on Form S-8 (the "Registration
Statement") the following documents previously filed with the Securities and
Exchange Commission (the "SEC") pursuant to the Securities Exchange Act of 1934,
as amended (the "Exchange Act"):

         (a)   The Registrant's Annual Report on Form 10-K for the fiscal year
               ended December 31, 1997;

         (b)   The Registrant's Quarterly Report on Form 10-Q for the quarter
               ended March 31, 1998;

         (c)   The description of the Registrant's Common Stock contained in the
               Registration Statement filed pursuant to Section 12 of the
               Exchange Act, including any amendment or report filed for the
               purpose of updating such description.


         All documents subsequently filed by the Registrant pursuant to Section
13(a), 13(c), 14 or 15(d) of the Exchange Act after the date of this
Registration Statement and prior to the filing of a post-effective amendment

incorporated by reference into this Registration Statement and to be a part
hereof from the date of filing of such documents. Any statement contained in a

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         The Business Corporation Law of the State of New York ("BCL") provides
that if a derivative action is brought against a director or officer, the
Registrant may indemnify him or her against amounts paid in settlement and
reasonable expenses, including attorneys' fees incurred by him or her in
connection with the defense or settlement of such action, if such director or
officer acted on good faith for a purpose which he or she reasonably believed to
be in the best interests of the Registrant, except that no indemnification shall
be made without court approval in respect of a threatened action, or a pending
action settled or otherwise disposed of, or in respect of any matter as to which
such director or officer has been found liable to the Registrant. In a
nonderivative action or threatened action, the BCL provides that the Registrant
may indemnify a director or officer against judgments, fines, amounts paid in
settlement and reasonable expenses, including attorneys' fees incurred by him or
her in defending such action if such director or officer acted in good faith for
a purpose which he or she reasonably believed to be in the best interests of the
Registrant.

         Under the BCL, a director or officer who is successful, either in a
derivative or nonderivative action, is entitled to indemnification as outlined
above. Under any other circumstances, such director or officer may be
indemnified only if certain conditions specified in the BCL are met. The
indemnification provisions of the BCL are not exclusive of any other rights to
which a director or officer seeking indemnification may be entitled pursuant to
the provisions of the certificate of incorporation or the by-laws of a
corporation or, when authorized by such certificate of incorporation or by-laws,
pursuant to a shareholders' resolution, a directors' resolution or an agreement
providing for such indemnification.

         The above is a general summary of certain indemnity provisions of the
BCL and is subject, in all cases, to the specific and detailed provisions of
Sections 721-725 of the BCL.

         Article IX, Section 1 of the Registrant's By-laws provide that the
Registrant shall indemnify any present or future director or officer from and
against any and all liabilities and expenses to the maximum extent permitted by
the BCL as the same presently exists or to the greater extent permitted by any
amendment hereafter adopted.

         Section 726 of the BCL also contains provisions authorizing the
Registrant to obtain insurance on behalf of any such director and officer
against liabilities, whether or not the Registrant would have the power to
indemnify against such liabilities. As permitted by law, the Registrant
maintains and pays premiums for directors' and officers' liability insurance
policies.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED

                  Not applicable.

ITEM 9.  UNDERTAKINGS

          (a)  Rule 415 offering. The undersigned Registrant hereby undertakes:

               (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement:

                      (i) To include any prospectus required by section 10(a)(3)
of the Securities Act of 1933 (the "Act");




                                       3


   5


                      (ii) To reflect in the prospectus any facts or events
arising after the effective date of the Registration Statement (or the most
recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in the
Registration Statement;

                      (iii) To include any material information with respect to
the plan of distribution not previously disclosed in the Registration Statement
or any material change to such information in the Registration Statement.

         provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this
section do not apply if the information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports
filed with or furnished to the Commission by the Registrant pursuant to section
13 or section 15(d) of the Exchange Act that are incorporated by reference in
the Registration Statement.

               (2) That, for the purpose of determining any liability under the
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

               (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

         (b)   Subsequent Exchange Act Documents. That, for purposes of
determining any liability under the Act, each filing of the Registrant's annual
report pursuant to section 13(a) or section 15(d) of the Exchange Act (and,
where applicable, each filing of an employee benefit plan's annual report
pursuant to section 15(d) of the Exchange Act) that is incorporated by reference
in the Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         (c)   Indemnification. Insofar as indemnification for liabilities 
arising under the Act may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
