The Multiquip 1877100130 Volute Casing is a genuine OEM component designed for the CP-20H centrifugal pump. Sourced directly from Multiquip, this part meets the original engineering specifications for the CP-20H, ensuring a correct, direct installation with no guesswork on fit. Whether you are rebuilding a worn pump or replacing a damaged housing, the part is the factory-specified casing for restoring full pump performance.
Key Features
- Genuine OEM Casting Integrity — Manufactured to Multiquip's original dimensional tolerances, ensuring the internal flow path geometry matches the design spec of the CP-20H pump exactly.
- Direct Bolt-On Replacement — Matches the original mounting flange and port configuration of the CP-20H, allowing straightforward installation without modification to surrounding pump components.
- Confirmed CP-20H Fitment — Verified for use on the STOW CP-20H centrifugal dewatering pump series.
- Restores Full Flow Capacity — A cracked, eroded, or damaged volute casing causes pressure loss and reduced output volume; replacing it with the correct OEM casing brings the pump back to its rated discharge performance.
- Corrosion-Resistant Construction — Built to withstand continuous contact with water and abrasive particulates typical of dewatering applications, extending service intervals between pump overhauls.
The volute casing is the outer pump housing that surrounds the impeller and forms the spiral-shaped chamber that converts the high-velocity flow generated by the impeller into usable pressure and volume at the discharge port. Its precisely shaped internal profile is critical to maintaining efficient hydraulic performance — even minor erosion, cracking, or distortion of the casing wall disrupts the flow path and causes a measurable drop in discharge pressure and output rate. When the volute casing is damaged or worn, the pump will struggle to reach its rated flow capacity, and in severe cases may lose prime entirely. Replacing it with the correct OEM part restores the pump's original hydraulic efficiency and extends its working service life.
