The Multiquip 1803100130 is a genuine OEM Volute Casing designed for the QP205SH centrifugal pump. As a direct factory replacement, this part ensures the pump housing geometry matches original specifications, preserving flow efficiency and discharge performance. Verified for use on QP205SH series equipment, this casing installs in place of the original without modification.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional standards, ensuring the casing wall profile and port geometry match the pump's engineered design.
- Direct Housing Replacement — Replaces the original volute casing on the QP205SH with matching bolt patterns and inlet/outlet port alignment for a straightforward swap.
- Confirmed QP205SH Fitment — Specifically sourced for the QP205SH centrifugal pump; cross-reference part number 1803100130 before ordering to confirm compatibility.
- Sustained Flow Performance — A correctly sealed and undamaged volute casing maintains the pressurized spiral chamber that converts impeller velocity into discharge pressure — a cracked or eroded casing causes significant pressure loss and flow drop-off.
- Corrosion-Resistant Integrity — The casing is built to resist the abrasive and corrosive conditions typical in dewatering and water transfer applications, supporting long service intervals.
The volute casing is the main pump body that surrounds the impeller and forms the spiral chamber responsible for collecting and directing water flow toward the discharge outlet. As the impeller spins, the gradually widening volute channel converts rotational energy into pressure, allowing the pump to move water efficiently over distance and elevation. When the casing is cracked, worn, or improperly sealed, the pump loses the ability to build pressure, resulting in reduced output, cavitation, or complete loss of prime.
