Product Overview

Restore the seal-supporting structure of your compatible commercial pool pump with the Pentair 356795Z EQ Series® Replacement Seal Plate. This genuine Pentair replacement component is designed for supported EQ Series commercial plastic pump configurations.

The seal plate forms part of the pump’s wet-end assembly and supports the mechanical shaft seal where the motor shaft enters the pump. A damaged plate or seal seat can compromise sealing and lead to leaks. Replacing a cracked, distorted, or otherwise unserviceable plate helps restore the proper foundation for reassembling the pump.

Listed at 11 inches x 2.5 inches, this seal plate is suitable for compatible EQ pump repairs and rebuilds. It provides a replacement option when the surrounding pump components remain serviceable, helping avoid unnecessary replacement of the entire pump.

Important Purchase Notice: This listing is for the seal plate only. The mechanical shaft seal, seal-plate O-ring, impeller, diffuser, motor, and mounting hardware are separate components unless specifically stated. Confirm the pump model and applicable parts diagram before ordering.

Specifications

Warranty & Compatibility

Compatibility

Some catalogs identify the EQ seal plate as 356795, while Pentair’s illustrated parts list also uses 356795Z. Confirm the correct replacement reference for your equipment before purchasing.

Installation and Replacement Guidance

Installation should be completed by a qualified commercial pool professional. Disconnect electrical power, isolate the pump, and relieve system pressure before disassembly.

Inspect the mechanical shaft seal, seal-plate O-ring, impeller, diffuser, and mating surfaces while the pump is open. Replace worn sealing components and follow Pentair’s assembly and alignment instructions.

A new seal plate will not resolve every pump leak. A damaged shaft seal, deteriorated O-ring, or another failed component may be the cause. Diagnose the source before ordering.

Warranty

Manufacturer warranty coverage is subject to Pentair’s applicable replacement-part terms, installation requirements, and proof of purchase.

Customer-Facing Q&A

Q: Will this fit every Pentair commercial pump?
A: No. It is intended for supported EQ Series configurations. Verify the exact pump model and parts diagram.

Q: When should the seal plate be replaced?
A: Replace it when inspection identifies cracks, distortion, damaged mounting areas, or an unserviceable seal seat.

Q: Should I replace the shaft seal during this repair?
A: A new, correctly matched mechanical seal is recommended during seal-plate replacement. Inspect the O-ring and other accessible sealing components as well.
