3.17 Mount the seal drive halves 2 around the shaft and loosely fasten

them together with the shoulder screws 414 provided. Line up the

pins in the seal drive with the holes in the rotating face and slide the

seal drive towards the rotating face until a 3 mm (0.12 inch) spring

gap is achieved using the two 1/8" Allen wrenches as spacers.

Tighten the shoulder screws completely and lock seal drive to the

shaft.

On designs that incorporate set screws 57 in the seal drive, after

tightening shoulder screws 414 , tighten the set screws 57 to lock

the seal drive to the shaft.

before start-up, paragraph 4.

For special problems encountered during installation, contact your nearest

Flowserve Sales and Service Representative or Authorized Distributor.

4 Operational Recommendations

The MSS seal is designed to run dry at speeds of up to 350 rpm. If

operated dry, no special environmental controls are necessary. For wet

operation of up to 1750 rpm, make sure that the seal water ush, Plan 32,

is adequate to remove seal-generated heat and that the ush is on

before start-up of the equipment. Contact your nearest Flowserve Sales

and Service Representative or Authorized Distributor for seal ush

requirements.

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 certicate 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.
