FOR IMMEDIATE RELEASE

Flowserve Announces Filing Delays

DALLAS — Oct. 26, 2004 — Flowserve Corp. (NYSE: FLS) today said that, as part of its internal control improvement activities and related account reconciliation work, it will delay its second and third quarter 2004 Form 10-Q filings with the Securities and Exchange Commission.

The company believes that it will amend its previously announced financial results for the second quarter of 2004 in its second quarter Form 10-Q filing. These changes include certain post-closing adjustments and/or recently identified out-of-period expenses. The post-closing adjustments include the recognition of certain additional expenses following the quarter’s end. The out-of-period expenses relate primarily to reconciliation of intercompany and deferred tax accounts. Neither are expected to impact the net cash balance during the affected periods.

Exhibit 99.1

Depending on the amount of these out-of-period expenses, the company will assess whether a restatement is needed for certain past periods. Based on current information, the company estimates the cumulative impact on net income over the applicable periods to be less than $10 million, subject to revision following further analysis.

Internal Controls, Sarbanes-Oxley Act Compliance and Associated Costs

Selling, general and administrative expenses for the third and fourth quarter of 2004 are expected to reflect approximately $15 million of aggregate incremental costs associated with retaining a Big Four firm for assistance with Sarbanes-Oxley documentation and testing of internal controls. In the third quarter of 2004, the company intensified its activities and increased resources toward this initiative.

Because of the company’s decentralized global operations, 2004 financial management changes, previous restatement of earnings and delays in completing newly required Sarbanes-Oxley control documentation, the company expects a delay in the completion of the integrated audit by its outside auditors of the company’s 2004 financial statements and internal controls. The company thus expects to file its 2004 Form 10-K in the latter part of the second quarter of 2005.

The company further believes that, as a result of its Sarbanes-Oxley Section 404 work and its consultation with its auditors, it will have certain material weaknesses in its internal controls at the 2004 year end. These weaknesses are anticipated to include, among other matters, issues in the reconciliation of the intercompany, deferred tax, and

Exhibit 99.1

currency translation accounts, in addition to certain internal control issues described in its prior SEC filings.

However, the company plans to take whatever action is necessary to cause its financial statements in its 2004 Form 10-K filing with the SEC to be fairly stated in accordance with generally accepted accounting principles. The company also expects to finalize its plan, by the time of filing of this Form 10-K, to remediate any identified material control weaknesses.

Third Quarter Bookings Strong, Debt Repayment of $35 million.

Third quarter 2004 bookings increased approximately 14 percent (inclusive of currency effects of 3 percent) to approximately $665 million, compared with the prior year period, reflecting improving business conditions. Backlog at the end of the third quarter was approximately $897 million, approximately 7 percent higher than the prior year level (inclusive of currency effects of 3 percent). In the third quarter of 2004, the company continued to generate solid cash flow from operations and made optional debt repayments totaling $35 million. As a result, for the end of the third quarter, the company expects its steadily improving net debt-to-capital ratio to fall below 50 percent.

Because of the time needed to clarify the accounting issues described above, the company is temporarily deferring its announcement of its third quarter 2004 financial results.

Exhibit 99.1

“Business conditions for the company continue to look good, as witnessed by the continued strong bookings and backlog,” said Flowserve Chairman, President and Chief Executive Officer C. Scott Greer. “We are upbeat for 2005, especially given the strength of current bookings, coupled with the fact that a high percentage of the Sarbanes-Oxley consulting expenses should not recur. Upon completion of our analysis of the aforementioned matters, we will advise if any change in our full year earnings forecast is required. Flowserve is addressing the Sarbanes-Oxley compliance work not only as a requirement, but also as an opportunity to create business value by enhancing the internal controls of the company. These efforts, coupled with the improved business outlook and rebuilding of our finance team under incoming chief financial officer, are foundational elements as we move forward as a company.”
