The Multiquip 0458220100 Impeller Seal Washer is a genuine OEM component designed for QP and MQ series trash and centrifugal pump equipment, including the QP2TK, QP3TK, QP3TS, QP3TH, QP3TB, QP3TZ, QP3THX, QP4TK, QP4TKT, QP4TB, QP4TZ, MQ62TK, and MQ62TDD. Sourced directly from Multiquip, this part meets the exact specifications of the original component installed at the factory. Keeping the impeller seal in proper working condition is critical to maintaining pump efficiency and preventing fluid bypass around the impeller. DHS Equipment supplies this genuine OEM part to help you restore your pump to full operating condition quickly and correctly.
Key Features
- Genuine OEM Sealing Performance — Manufactured to Multiquip's exact material and dimensional specifications, ensuring proper compression and sealing at the impeller interface.
- Direct-Fit Installation — Engineered to seat correctly against the impeller housing without trimming or shimming, streamlining your pump rebuild or service procedure.
- Broad Pump Family Coverage — Fits QP2TK, QP3TK, QP3TS, QP3TH, QP3THX, QP3TZ, QP3TB, QP4TK, QP4TKT, QP4TB, QP4TZ, MQ62TK, and MQ62TDD pump models.
- Preserves Pump Output Efficiency — A properly seated impeller seal washer maintains hydraulic pressure at the impeller, supporting rated flow and head performance across the pump's operating range.
- Fluid Containment Integrity — In fuel and fluid-handling equipment, a correctly functioning seal washer prevents leakage and contamination around the impeller shaft, protecting both the pump and the surrounding work environment.
The impeller seal washer sits at the interface between the impeller and the pump casing, creating a controlled sealing surface that limits fluid from bypassing the impeller and recirculating internally. When this washer wears, deforms, or fails, the pump loses priming ability, flow rate drops, and the motor may begin running under increased load as it struggles to compensate for internal bypass. Replacing a worn impeller seal washer restores the pump's ability to move water and debris efficiently, and is a standard step in any thorough pump rebuild or preventive service.
