to resist corrosion by most chemicals. However, do not expose
the CPM PX materials of construction to products outside of their
corrosion limits. Consult Flowserve, Flow Solutions for assistance.
4.2 Do not exceed the Pressure limits of the CPM PX seal, consult
Flowserve Flow for assistance.
4.3 Do not exceed the temperature limits of the CPM PX seal. The
materials of construction are listed on the box label. Turn on cooling
water to the supply tank before start up if the tank has coils.

nearest Flowserve Sales and Service Representative or Authorized
Distributor.
5 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.
