This product is a precision sealing device. The design and dimensional tolerances are critical to
seal performance. Only parts supplied by Flowserve should be used to repair this seal. These are
available from the numerous Flowserve stocking locations.
To order replacement parts, refer to the part code, order number or B / M number, which can
be found on the assembly drawing. It is recommended to keep a spare seal on stock to reduce
equipment downtime.
All liabilities and warranties to Flowserve for damage incurred through the use of non-original
replacement parts and accessories will be rendered null and void.
Please note that special manufacturing and delivery specifications exist for all parts of our
products manufactured or produced by ourselves and the replacement parts are always offered
in accordance with the latest technology and with the most current regulations and laws.
Flowserve seals can normally be reconditioned. When repair is necessary, the seal should be
carefully removed from the equipment (reinstall the centring tabs or setting plates if applicable).
Decontaminate the seal assembly and return it to a Flowserve authorized repair facility
with an order marked “Repair or Replace”. A signed certificate of decontamination must
be attached.
A Material Safety Data Sheet (MSDS) must be enclosed for any product that came in contact
with the seal. The seal assembly will be inspected and, if repairable, a quotation will be made for
restoring it to its original condition. Upon acceptance of the quotation, the parts will be rebuilt,
tested, and returned to sender.
