4.2 PUMP SEAL REPLACEMENT
A. The unit pump seal is a carbon/niresist shaft
seal assembly including a stationary member,
rotating member and tension spring (figure
4.2A).
B. The operator can determine the pump seal is
leaking when fluid is identified leaking from
the pump case adapter.
C. Generally, a pump seal will leak due to
inadequate unit pressure, excessive flow and poor fluid quality.
D. The operator should follow this procedure to replace the pump seal:
1. Disengage process operations. The operator must be certain process fluid
pressure is relieved (pressure gauge reads “0”) and water system flow is shut off
and all pressure relieved.
2. Disengage main power supply. The operator must verify the Power light on the
display is off.
3. Close the suction and discharge valves.
4. Drain pump. The pump can be drained by using the drain plug located on the
pump case.
5. Locate and remove the three motor wire leads from the motor wiring terminals.
The operator should note the wire terminal locations to ensure correct rewiring.
The power cord should be removed from the motor housing (figure 4.2B).
6. Locate and remove the pump casing bolts. These bolts secure the motor and
motor adapter to the pump casing (figure 4.2C).
7. Separate the motor and motor adapter from the pump casing to expose the pump
impeller (figure 4.2D). Remove the motor and motor adapter from the unit and
place on a workbench to continue the procedure.
8. Locate and remove the dust cap from motor end to expose slotted motor shaft.
