SSV CARTRIDGE SEAL INSTALLATION
CARTRIDGE TYPE SEAL INSTALLATION
1. Close all necessary suction and discharge valves to
isolate the pump from the system.
2. Drain the liquid from the pump by removing the
drain plug and opening the needle valve on the vent
plug.
3. Remove the coupling guards, the 4 coupling hex cap
screws, the coupling and coupling drive pin.
4. Remove the 4 motor hex cap screws (inner screws)
on the seal housing.
5. Loosen the 4 set screws located around the ID of the
pump shaft.
6. Remove the cartridge seal using the two tapped holes
provided on the gland of the cartridge seal by
threading two of the hex cap screws into these holes
and evenly tightening these screws. Lift and remove
the cartridge seal between the pump and motor
shaft.
7. Inspect the pump shaft for any burrs or debris. Any
burrs should be ground smooth with (fi ne grit) emery
paper.
8. Install a new o-ring on the turned fi t of the new
cartridge seal. Lubricate the o-ring located in the ID
of the cartridge seal. Use a lubricant compatible with
the seal elastomers to hold the o-ring.
9. Install the new cartridge seal on the pump by
carefully sliding it between the pump and motor
shaft and then sliding it into position
10. Reinstall the coupling pin and locate the space shim
on the shaft on the seal housing. If the shim is not
available, a 5 mm spacer can be used. See step 11 in
Figure 5.
11. Reinstall the coupling halves and evenly tighten the
coupling bolts and torque them to 37 lbs ft (50 Nm)
for 184TC frame motors and torque coupling bolts
to 48 lbs ft (65 Nm) for all larger frame sizes.
Remove the spacer shim and save for future use. See
step 12 in Figure 5.
12. Rotate the shaft by hand to insure that the pump and
motor rotate freely. Reinstall the coupling guard.
13. The pump and system should be vented prior to
starting the pump. For sizes 33SV-92SV the vent
plug is supplied with an internal needle valve, so
it is not necessary to remove the vent plug. Simply
unscrew the needle valve half way to open the valve
to allow air to escape. (For sizes 33SV-92SV , if the
pump is supplied with a cartridge seal, remove the
vent plug located on the gland plate beneath the
coupling.)
NOTE: Place a loose rag over the open vent port to
prevent large amounts of liquid from being
sprayed on the pump and adjacent
equipment.
Care should be exercised if you are
CAUTION
pumping hot water or chemicals to avoid
personal injury.
14. After installing the coupling, tighten the four set
screws located in the collar of the cartridge seal to
secure the seal to the pump shaft.
15. Rotate the shaft by hand to insure that the pump and
motor rotate freely. Reinstall the coupling guard.
16. Use vent connections on cartridge seal for proper
venting.
