Compatibility & Installation Notes
This kit is designed for Pentair variable-speed pump models and single-speed models that share the same pump platform. Before installing, confirm the existing pump’s model number and manufacture date to ensure compatibility. When replacing the seal plate kit, power off the pump, relieve system pressure, open the pump housing, remove the existing seal plate/gasket, clean the sealing surface thoroughly, then install the new kit and reassemble per manufacturer torque instructions.
Troubleshooting & Service Tips
-
Leakage at motor housing: Check that the gasket is properly seated, seal plate bolts are evenly torqued, and the mechanical seal is correctly installed.
-
High motor moisture or corrosion: A worn or improperly installed seal plate/gasket is a common cause—replacement of the entire kit typically resolves this issue.
-
Pump failing to prime or low suction: Ensure the seal plate is correctly aligned, the gasket isn’t pinched, and the shaft seal is not leaking internally.
Maintenance Tip
As part of your annual pump service, inspect the seal plate area for signs of moisture, corrosion, or leaks. Even if no leak is present, replacing the seal plate kit at the first sign of wear or damage can save on future downtime and protect the pump motor. Keep the replacement kit on hand to minimize service interruption.
