The Multiquip 9430000130 Volute Casing is a genuine OEM component designed for QP402H and QP402B centrifugal pumps. As a direct OEM replacement, this casing is produced to the same specifications as the original part, ensuring a correct fit within the pump housing without improvisation or adaptation. Sourced directly through authorized Multiquip supply channels, the 9430000130 is the right choice when restoring your QP402-series pump to full operating condition. Confirm your model code against QP402H or QP402B before ordering to ensure compatibility.
Key Features
- OEM-Matched Housing Geometry — Cast and machined to the same internal profile as the original, maintaining the precise volute shape that governs hydraulic efficiency and output pressure.
- Drop-In Replacement for QP402-Series Pumps — Engineered to bolt directly into QP402H and QP402B pump assemblies using existing mounting points and hardware.
- QP402H and QP402B Fitment Confirmed — Verified genuine OEM part for both the Honda-engine and Briggs and Stratton-engine variants of the QP402 centrifugal pump line.
- Restores Full Flow and Pressure Performance — A cracked, eroded, or worn volute casing causes pressure loss and cavitation; replacing it with the correct OEM part brings the pump back to rated output.
- Genuine Multiquip Part Number 9430000130 — Carries authentic OEM traceability, so you can order with confidence that you are receiving the correct component for your machine.
The volute casing is the primary hydraulic body of a centrifugal pump. It surrounds the impeller and converts the high-velocity flow generated by the spinning impeller into useful pressure, channeling water from the pump inlet to the discharge outlet through its gradually expanding spiral chamber. When the volute casing is cracked, corroded, or dimensionally compromised, the pump loses its ability to build and sustain discharge pressure, resulting in reduced flow rates, excessive cavitation, and potential damage to surrounding components. Replacing a damaged casing with the correct OEM part is essential to restoring the pump's hydraulic integrity and protecting the impeller and seal assembly from further wear.
