(1)   This registration statement serves to register additional shares of
      Flowserve Corporation Common Stock to be offered or sold under the
      Flowserve Corporation Retirement Savings Plan (formerly named the
      Flowserve Corporation Savings and Thrift Plan). In addition, pursuant to
      Rule 416(c) under the Securities Act of 1933 (the "Securities Act"), this
      Registration Statement also covers an indeterminate amount of interests to
      be offered or sold pursuant to the employee benefit plan described herein.
      Securities relating to such plan were previously registered with the
      Commission under Registration No. 33-72372.

(2)   Estimated solely for purposes of calculating the registration fee required
      by Section 6(b) of the Securities Act, the proposed maximum aggregate
      offering price of the Registrant's Common Stock was calculated in
      accordance with Rule 457 under the Securities Act as the average of the
      high and low prices per share of the Registrant's Common Stock on June 30,
      1999 as reported on the New York Stock Exchange, multiplied by 2,000,000,
      the number of shares of the Registrant's Common Stock to be offered or
      sold pursuant to the employee benefit plan described herein.

(3)   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.

              SEC on July 18, 1997, pursuant to Section 12 of the Exchange Act.

         (d)  The description of the Registrant's Series A Junior Participating

         (e)  The Annual Report on Form 11-K of the Flowserve Corporation

         All documents subsequently filed by the Registrant or by the Flowserve

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL

                  None.

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 provides 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. Article IX, Section 2 of the Registrant's By-laws
authorizes the Registrant to enter into indemnification agreements with
directors and officers. The Registrant has entered into indemnification
agreements with all persons currently serving as directors and officers.

         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 8. EXHIBITS

         See Exhibit Index at page 7. The Registrant hereby undertakes that it
will submit or has submitted the Plan and any amendment thereto to the Internal
Revenue Service (IRS) in a timely manner and has made or will make all changes
required by the IRS in order to qualify the Plan. The Plan has received a
determination letter from the IRS, dated December 26, 1995, stating that the
Plan is qualified under Section 401(a) of the Internal Revenue Code.

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");

                 (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


                                       3

   5


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.
