5. Ensure that the cleaning solution is compatible with all of
the pump materials.
SOILED ROTOR RETAINER CLEANING PROCEDURES:
1. Use steps 1, 4 and 6-8 from the disassembly procedures
to remove the rotor retainer components.
2. If rotor retainer blind tapped hole is soiled, submerge
and soak rotor retainer for 5 minutes in Clean Out of
Place tank with suitable cleaning solution.
3. Scrub both external and internal threads with appropriate
bristle brush and suitable cleaning solution.
4. Rinse with clean water and dry blind tapped hole with
clean air.
5. Use new O-rings when reassembling the pump. For
mechanically sealed pumps, follow steps 27 and 29-31
from the assembly procedures to reassemble the pump.
For O-ring sealed pumps, follow steps 13 and 15-17
from the assembly procedures to reassemble the pump.
As long as the thrust bearing was not adjusted, the end
clearance should still be set correctly. Verify the end
clearance and adjust if necessary before putting pump
back into service. If the locknut needs to be retightened
or the end clearance needs to be adjusted, follow the
complete assembly procedures. Do not tighten the
locknut or make major (> 0.005”) adjustments to the end
clearance of mechanically sealed pumps while the seal
is installed in order to avoid damaging the seal faces.
Note: Install new rotor retainer if debris remains after
cleaning. It is recommended that the rotor retainer O-rings be
replaced every 12 months to maintain a tight seal.
