The Multiquip 0482200750 is a genuine OEM O-Ring (Volute Casing) designed for Multiquip centrifugal and dewatering pump models including QP303B, QP303H, QP402H, QP205SLT, QP305SLT, QPT205SLT, and QPT305SLT. As a direct OEM replacement, this seal is manufactured to the same specification as the original component installed at the factory, ensuring a correct, leak-free fit. Keep part number 0482200750 on hand for routine maintenance or emergency pump repair to avoid extended downtime on the job. DHS Equipment supplies this part direct — if you have questions about fitment, contact our team for confirmation.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to the exact material grade and compression profile required for the volute casing interface, maintaining a proper hydraulic seal under pump operating pressures.
- Direct-Fit Replacement — Matches the original O-Ring profile precisely, seating correctly in the volute casing groove without trimming, stretching, or modification.
- Broad Centrifugal Pump Compatibility — Confirmed fitment for QP303B, QP303H, QP402H, QP205SLT, QP305SLT, QPT205SLT, and QPT305SLT series pumps.
- Leak Prevention at the Casing Joint — A correctly seated volute casing O-Ring keeps pump efficiency high; a worn or cracked seal allows water to bypass the impeller, reducing output and flow rate.
- Fuel and Fluid Compatibility — Formulated to resist water and the environmental conditions common in dewatering and transfer pump applications, extending service life between replacements.
The volute casing O-Ring forms the primary seal between the pump's volute casing halves or between the casing and the pump housing, preventing water from escaping at that joint during operation. Without a properly functioning seal, the pump loses prime, flow rate drops, and water can leak externally — reducing pumping efficiency and potentially damaging surrounding components. Replacing this O-Ring as part of routine pump service or whenever the casing is disassembled is a low-cost step that keeps the pump operating at full capacity.
