Key Features
- Genuine OEM Construction — Manufactured to the original casting geometry and material grade required for pump housing integrity, maintaining consistent internal flow path dimensions.
- Direct-Fit Replacement for QP-401 — Engineered specifically for the QP-401 quick-prime pump, with matching bolt patterns and port dimensions for a straightforward installation.
- Maintains Pump Output Efficiency — A correctly fitted volute casing channels fluid energy from the impeller into pressure, keeping the pump operating at its rated flow and lift capacity.
- Resists Abrasion and Wear — The OEM casing material is suited to handle the abrasive slurries and debris-laden water typical of quick-prime pump applications.
- Verified QP-401 Fitment — Part number 1401000130 is confirmed for QP-401 series equipment, giving you confidence you are ordering the correct component before it ships.
The volute casing is the main housing that surrounds the impeller in a centrifugal pump. Its curved internal shape is specifically designed to convert the high-velocity fluid thrown outward by the impeller into usable pressure at the discharge port. When a volute casing cracks, erodes, or is damaged, the pump loses the ability to build prime and maintain flow, resulting in a significant drop in discharge pressure or complete loss of pumping capability. Replacing a worn or damaged casing with a genuine OEM part like the part restores the precise internal geometry needed for the QP-401 to deliver its rated performance.
