The Multiquip 1466251241 is a genuine OEM Impeller Washer 42 x 9.8 x T6.0 designed for QP4TH, QP4TZ, QP4TK, QP4TKT, and QPT405SLT series pump equipment. As a direct Multiquip OEM component, this washer is manufactured to the exact dimensional and material specifications required by these pump families. Sourced and sold by DHS Equipment, part number 1466251241 ensures a correct, verified fit across compatible trash pump and centrifugal pump models. Keeping this washer in proper condition is essential to maintaining impeller function and pump integrity.

Key Features

• Exact OEM Dimensions — Manufactured to precise 42 x 9.8 x T6.0 specifications, ensuring correct seating and load distribution at the impeller interface.
• Genuine Multiquip Part — Sourced directly from Multiquip, this washer meets the same material grade and thickness tolerance as the original component installed at the factory.
• Broad Pump Family Coverage — Compatible with QP4TH, QP4TZ, QP4TK, QP4TKT, and QPT405SLT models, covering both trash pump and centrifugal pump applications in the Multiquip lineup.
• Protects Impeller and Shaft — This washer absorbs axial load and prevents metal-to-metal contact between the impeller and pump housing, extending the service life of surrounding components.
• Direct Service Replacement — Drops into position during routine pump maintenance or impeller service without requiring modification to adjacent hardware.

The impeller washer sits between the impeller and the pump casing or shaft shoulder, providing a controlled bearing surface that manages axial thrust and prevents wear on critical mating components. Without a correctly sized and properly conditioned washer in place, the impeller can shift under load, leading to increased vibration, accelerated wear on the pump shaft, and a drop in pumping efficiency. Replacing this washer as part of any impeller service keeps the pump running at full output and protects the surrounding assembly from premature damage.
