The Multiquip 9430100010 Casing is a genuine OEM replacement designed for QP402H and QP402B centrifugal pumps. As a direct OEM component sourced through an authorized Multiquip parts channel, it is manufactured to the same specifications as the original part installed at the factory. This casing is confirmed to fit QP402H and QP402B models, making it the correct choice when an exact replacement is required for these pump families.
Key Features
- Genuine OEM Construction — Manufactured to the original dimensional and material specifications for the pump casing, ensuring proper hydraulic clearances and structural integrity under continuous pumping loads.
- Direct Drop-In Replacement — Matches the original bolt pattern, volute geometry, and port sizing of the QP402H and QP402B, allowing installation without machining or modification to mating components.
- Confirmed Fitment — Verified for QP402H and QP402B centrifugal pump models; always cross-reference your part number before ordering to confirm correct application.
- Maintains Pump Flow Efficiency — A damaged or cracked casing causes pressure loss and reduced flow output; replacing it with a correctly sized OEM casing restores designed pumping capacity and discharge pressure.
- Corrosion and Wear Resistance — Built from materials selected for pump casing service, where abrasion from water-borne debris and exposure to moisture are constant operating conditions.
The pump casing is the outer housing that encloses the impeller and forms the volute — the curved chamber that converts the impeller's rotational energy into fluid pressure and directs water toward the discharge port. It plays a direct role in maintaining pumping efficiency; any cracks, erosion, or warping in the casing wall reduces the pressure differential the pump can generate, resulting in lower flow rates and poor prime retention. Replacing a worn or damaged casing with a genuine OEM part restores the correct internal clearances and keeps the pump operating at its rated capacity.
