The above torque values will be applied

only when the casing hydro test pressure is equal to

or less than the values showing in the following table.

Any hydro test pressure exceeding these values must

have torque values cleared by Flowserve.

The above torque values apply only to

standard stud material, i.e. ASTM A193 GrB7. Any

other material must have torque values cleared by

FLOWSERVE.

The above torque values assume good

thread well greased.

When reassembling the pump, all fasteners

must be tightened to the correct torque value.

Failure to observe this warning could result in

injury to operating personnel.

6.6 Disassembly

For a better understanding of this section please refer

to the exploded views drawings in section 8.

6.6.1 Dismantling procedure

a) Remove all auxiliary piping and instrumentation

that will interfere with disassembly, and drain oil

from bearing housings.

Use extreme caution not to expose

maintenance personnel to hot liquids when

removing auxiliary piping or draining bearing

housings.

b) Remove temperature detectors (if supplied) and

all other instruments from bearing housings.

c) When mechanical seals are used, loosen piping

and seal gland bolting.

6.6.2 Removal of seal chamber parts

To remove mechanical seal from pump:

a) Install setting plates/eccentric washer in place.

b) Loosen drive collar.

c) Remove gland bolting.

d) Slide mechanical seal from shaft after bearing

housings are removed as described in 6.6.4 and

6.6.5.

Seal may be disassembled/inspected/reassembled

per seal manufacturer’s drawing and instructions in

Appendix of this manual.

After reassembly of seal, setting

plates/eccentric washers must be removed before

start-up.

6.6.3 Coupling removal

Remove coupling guard. Remove coupling bolting

and remove the spacer piece (if used). Loosen set-

screws in coupling nut and remove nut.
