Key Features
- OEM Sealing Integrity — Manufactured to Multiquip's original material and compression specifications, maintaining a proper fluid-tight seal at the casing cover interface.
- Drop-In Casing Cover Fit — Engineered to seat correctly at the pump casing cover without trimming, shimming, or additional hardware.
- Broad QP-Series Compatibility — Confirmed fitment for QP3TS, QP3THX, QP4TK, QP4TB, QP4TKT, QP4TZ, and QP4TH trash pump models.
- Leak Prevention at the Pump Housing — A correctly seated washer keeps pump pressure contained within the casing, sustaining flow rate and suction performance across heavy-duty trash pumping applications.
- Fluid System Safety — A failed or missing casing cover washer can allow pressurized fluid to escape at the housing joint — replacing it with the correct OEM part restores safe, contained pump operation.
The Seal Casing Cover Washer sits between the pump casing and its cover, creating a compressed seal that prevents fluid from escaping the pump housing at that joint. Without a properly functioning washer, internal pressure bleeds off at the casing seam, resulting in reduced flow, loss of prime, and potential fluid spray around the pump body. Replacing a worn or damaged washer with the correct OEM part restores the pump's sealed environment and ensures consistent performance during demanding trash pumping operations.
