The Multiquip 1889000132 is a genuine OEM Volute Casing designed for QP2TB, QP2TH, and QP2TK series pumps. As a factory-sourced component, it meets the exact material and dimensional standards of the original part, ensuring a correct fit within the pump housing. This casing is compatible across the QP2T pump family, covering centrifugal and trash pump configurations. Whether you are restoring pump performance or completing a scheduled rebuild, the 1889000132 delivers the precision fit that aftermarket casings cannot always match.
Key Features
- Genuine OEM Casting Integrity — Manufactured to the original material and wall-thickness specifications for the QP2T pump series, ensuring the internal flow path geometry is preserved exactly as engineered.
- Direct Housing Replacement — Matches the original bolt pattern and inlet/outlet port dimensions, allowing the casing to seat and seal correctly against the impeller and pump body without machining or shimming.
- Broad QP2T Series Fitment — Confirmed for QP2TB centrifugal pump, QP2TH trash pump, and QP2TK trash pump models, covering multiple engine configurations within the same pump platform.
- Sustained Flow Efficiency — A correctly fitted volute casing maintains the engineered pressure and flow rate of the pump; a cracked or eroded casing causes pressure loss, cavitation, and accelerated impeller wear.
- Structural Durability Under Load — The volute casing handles continuous hydraulic pressure and abrasive media in trash pump applications, making OEM material grade critical to service life in demanding site conditions.
The volute casing is the primary structural housing that surrounds the impeller and converts the high-velocity fluid discharged by the spinning impeller into usable pressure. Its spiral-shaped internal channel is precisely engineered to decelerate flow and build discharge head — any deviation in that geometry directly reduces pump output. When the casing cracks, erodes, or develops internal pitting from abrasive material, the pump loses prime more easily, output pressure drops, and the impeller is exposed to uneven hydraulic loads that shorten its service life. Replacing a damaged casing with a genuine OEM part restores the original hydraulic performance and protects the surrounding components.
