4 Operation
Following these recommendations will ensure maximum MTBPM
of the X-100 seal.
4.1 The X-100 is designed to resist corrosion by most chemicals. However,
do not expose the X-100 materials of construction to products outside
of their corrosion limits. The X-100 assembly drawing lists the materi-
als of construction. Contact Flowserve for chemical resistance ratings.
4.2 To request Pressure-Velocity (P-V) limits contact Flowserve.
4.3 The materials of construction are listed on the assembly drawing
supplied with the X-100 seal. Contact Flowserve for the temperature
limits of materials.
4.4 Do not start up or run the X-100 dry. Product or flush fluid must be
in the seal cavity at all times during pump operation.
For any special problems encountered during installation, contact your
nearest Flowserve Sales and Service Representative or Authorized
Distributor.
5 Repair
5.1 To reset the pump impeller, follow plant safety procedures, see 1.1.
• reinstall the X-100 setting devices using the cap screws.
• loosen the X-100 cartridge drive collar set screws.
• adjust the impeller clearance following pump manufacturers
instructions.
• tighten the set screws on the X-100 cartridge drive collar.
• remove the setting devices by removing the cap screws.
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. These are available from
numerous Flowserve stocking locations. To order replacement parts,
refer to the part code number and B/M number. A spare backup seal
should be stocked to reduce repair time.
When repairs are not conducted at the customer's location, decontami-
nate the seal assembly and return it to Flowserve, 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, it will be rebuilt, tested, and returned.
