The Multiquip 1808000130 Volute Casing is a genuine OEM component designed for QP2H and QP2B series centrifugal pumps. As a direct OEM replacement, it is manufactured to the same specifications as the original part, ensuring a proper fit within the pump housing assembly. This casing is confirmed compatible with QP2H and QP2B models, making it the correct choice for restoring pump performance to original operating condition. Source this part with confidence through DHS Equipment, an authorized Multiquip parts distributor.
Key Features
- OEM-Matched Housing Geometry — Manufactured to original tolerances so internal flow passages align precisely with the impeller and discharge port, maintaining rated pump output.
- Direct-Fit Replacement — Mounts to the QP2H and QP2B pump assembly using the original bolt pattern and sealing surfaces, requiring no modification to the pump body or hardware.
- Confirmed QP2H and QP2B Fitment — Validated for both the Honda-engine and Briggs and Stratton-engine variants in the QP2 centrifugal pump family.
- Restores Full Discharge Pressure — A cracked or worn volute casing causes pressure loss and reduced flow; replacing it with part 1808000130 brings output back to rated capacity.
- Fluid-Contact Integrity — Built to withstand continuous contact with water and suspended debris typical in dewatering and water-transfer applications, resisting wear at the critical impeller clearance zone.
The volute casing is the outer spiral-shaped chamber that surrounds the impeller inside a centrifugal pump. As the impeller spins, the volute's gradually expanding channel converts the high-velocity water into pressure, directing flow efficiently toward the discharge outlet. When the volute casing is cracked, eroded, or damaged, the pump loses the ability to build and sustain discharge pressure, resulting in reduced flow rates and inefficient operation. Replacing a worn casing with a properly fitted OEM part like the Multiquip 1808000130 restores the pump's hydraulic efficiency and protects the impeller from uneven wear caused by improper clearances.
