Shaft seals handle demands of oil and gas sectors

A range of high duty mechanical shaft seals have been designed by Flowserve to provide reliable operation at the high speeds and pressures now required of critical pumps in the oil and gas sectors

A range of high duty mechanical shaft seals have been designed by Flowserve to provide reliable operation at the high speeds and pressures now required of critical pumps operating in the oil and gas industries.

For many years their BW seals have been supplied globally for water injection and crude oil/hydrocarbon condensate shipping pumps for both on-shore and off-shore installations.

Recent developments in new fields and technologies has resulted in the need for higher speed and pressure performance from these pumps.

As a result, seals have been developed for pumps running at speeds over 12,000 rpm and operating pressures over 100 bar, with static pressure requirements of over 400 bar.

The Flowserve UHTW range of seals have a proven successful record for difficult applications with the latest seal designs now used extensively on these high duty applications.

The UHTW can be supplied as a single, tandem or double seal arrangement and a wide variety of materials used in construction can be offered to suit the specific requirements of each application.

The QB seal range are API 682 compliant type A seals and are used in a variety of applications found in the oil and gas industries.

The QB can also be supplied in single or dual seal arrangements.

A special version of the QB called the QBQ is specifically designed for use on hydrocarbon applications with the advantage of very low emission rates.

The GSL is the latest range of dry running back up seals from Flowserve.

This seal eliminates the need for a costly and heavy seal support system when it is used as the secondary seal in a tandem seal arrangement.

The GSL uses a patented wavy face design to provide lift-off at the seal faces, preventing unnecessary seal damage.

Many GS seals, the fore-runner of the GSL design, are installed as the secondary seal in crude oil handling pumps world-wide.

An upgrade called the GSLX is also available for GS users to convert their seals to the latest technology.

To support their mechanical seals in the oil and gas industries Flowserve have a number of strategically positioned global Quick Response Centres (QRCs) and Service Centres (SCs) where seals can be overhauled, upgraded or new seals and spares supplied.

For the UK sectors there is a QRC located in Manchester.
