About This Item
The Pentair Seal Plate with Mechanical Seal (400031Z) is the OEM replacement seal plate kit for the WhisperFlo XF and IntelliFlo XF variable speed pump families. This kit includes both the seal plate and the mechanical seal as a matched assembly.
⚠️ IMPORTANT: KIT LISTING — SEAL PLATE AND MECHANICAL SEAL INCLUDED
This listing is a kit containing the seal plate and mechanical seal together — not the seal plate alone. Confirm you need both components before ordering; individual components may be available separately.
The seal plate sits between the pump's wet end and motor, housing the mechanical seal that prevents water from migrating along the motor shaft into the motor cavity. When the mechanical seal fails — typically indicated by water weeping from the back of the pump housing — the seal plate assembly must be removed to access and replace the seal. Replacing the seal plate and mechanical seal together as a matched kit restores the pump's water-tight integrity and protects the motor from moisture damage.

Pro Tip
When replacing the mechanical seal, inspect the seal plate itself for scoring, cracks, or warping before reuse. If the original seal failed due to dry-running or debris ingestion, the seal plate seating surface may be damaged — replacing both together with this kit eliminates that risk.
