5.1 Do not start up the equipment dry. Vent air from the casing of the
pump and the seal chamber before startup. Circulate clean product
or a clean fluid from an external source through the seal chamber
whenever the equipment is in operation, API Plan 11 or 32.
5.2 If the seal runs hot, check for proper seal setting, seal housing
dimensions, and check the bypass or flush line for obstructions.
Do not allow the equipment to run for any extended time if the
seal gets hot or squeals.
For special problems encountered during installation, contact your
nearest Flowserve Sales and Service Representative or Authorized
Distributor.
6 Repair
This product is a precision sealing device. The design and dimension
tolerances are critical to seal performance. Only parts supplied by
Flowserve should be used to repair a seal. To order replacement parts,
refer to the part code and B/M number. A spare backup seal should be
stocked to reduce repair time.
When seals are returned to Flowserve for repair, decontaminate the
seal assembly and include 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, it will be rebuilt, tested, and returned.
