The Multiquip 2258000130 Volute Casing is a genuine OEM component designed for the QP2TZ trash pump. As a direct OEM replacement, this part is manufactured to the same specifications as the original, ensuring a correct fit within the pump housing without the need for modifications. This casing is the right choice for operators looking to restore full pumping performance on QP2TZ equipment.
Key Features
- OEM-Grade Hydraulic Integrity — Cast to the same internal geometry as the original, preserving the precise flow channel dimensions that determine pump output and efficiency.
- Direct Housing Replacement — Mounts and seals to the pump body exactly as the factory casing did, aligning correctly with the impeller, inlet, and discharge port.
- Confirmed QP2TZ Fitment — Verified for use on the Multiquip QP2TZ trash pump, so you can order with confidence.
- Restores Full Flow Capacity — A cracked or eroded volute casing causes pressure loss and reduced discharge volume; replacing it with this OEM part brings pump output back to spec.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, part number 2258000130 carries the same material and dimensional standards as the component that shipped with the machine.
The volute casing is the outer housing that surrounds the impeller inside a centrifugal or trash pump. Its curved internal chamber is engineered to convert the high-speed rotation of the impeller into usable pressure and flow — the shape of the volute directly controls how efficiently the pump moves water and solids. When the casing cracks, corrodes, or wears through abrasive debris contact, the pump loses prime more easily, discharge pressure drops, and flow rate falls off noticeably. Replacing a damaged casing with the correct OEM part restores the hydraulic path and brings the pump back to its rated performance.
