The Multiquip 1391000130 Volute Casing is a genuine OEM component designed for QP303H and QP303B centrifugal pumps. As a direct Multiquip OEM part, it is manufactured to the same specification as the original, ensuring proper hydraulic geometry and a secure housing fit within the pump assembly. This casing is confirmed compatible with QP303H and QP303B series equipment, making it the dependable choice when restoring pump performance to original operating condition.
Key Features
- OEM-Matched Hydraulic Geometry — Cast to original tolerances so internal flow paths maintain the designed pressure-to-volume curve of the QP303 pump family.
- Direct Housing Replacement — Bolt pattern, inlet/outlet ports, and impeller clearance align with existing pump components, enabling straightforward installation without reworking mating parts.
- Confirmed Fitment — Verified for QP303H and QP303B centrifugal pumps; cross-reference part number 1391000130 before ordering to confirm your application.
- Sustained Flow Efficiency — A correctly sealed volute casing maintains the pressure differential needed for consistent discharge output; a cracked or worn casing causes pressure loss and reduced flow at the outlet.
- Genuine OEM Sourcing — Supplied as an authentic Multiquip part through DHS Equipment, ensuring material grade and dimensional accuracy match the original production casing.
The volute casing is the outer housing that surrounds the impeller in a centrifugal pump. Its spiral-shaped internal chamber is engineered to convert the high-velocity flow generated by the spinning impeller into usable pressure at the discharge port. When the casing is cracked, eroded, or improperly sealed, the pump loses the ability to build adequate pressure, resulting in reduced flow rate and poor priming performance. Replacing a damaged casing with a correctly dimensioned OEM part restores the pump's hydraulic efficiency and protects the impeller from misalignment wear.
