The Multiquip 0481310750 O-Ring is a genuine OEM seal designed for CP-30H and QP303H centrifugal and dewatering pumps. Sourced directly from Multiquip, this replacement O-Ring meets the exact material and dimensional specifications of the original component. It is a direct-fit replacement for both the STOW CP-30H and the QP303H pump families, making it straightforward to source the correct part without cross-referencing aftermarket catalogs. Keep a spare on hand to minimize seal-related service interruptions on active pump operations.
Key Features
- Genuine OEM Seal Material — Manufactured to the original compound and durometer specification, ensuring the correct compression set and fluid resistance for centrifugal pump service.
- Drop-In Seal Replacement — Matches the original groove dimensions and cross-section of the CP-30H and QP303H pump assemblies for a clean, tool-guided installation.
- Confirmed Fitment — Compatible with CP-30H STOW centrifugal pumps and QP303H centrifugal/dewatering pumps; verify against your model code before ordering.
- Leak Prevention at the Source — A correctly seated O-Ring maintains housing pressure and prevents fluid bypass, keeping pump output and prime consistent during operation.
- Fluid System Integrity — A degraded or cracked O-Ring allows air ingestion or fluid leakage that can cause loss of prime, cavitation, and accelerated wear on downstream pump components — replacing it promptly protects the broader pump assembly.
An O-Ring is a precision-molded elastomeric seal that sits within a machined groove to create a pressure-tight interface between mating pump components. In centrifugal and dewatering pumps like the CP-30H and QP303H, O-Rings are critical to maintaining housing integrity — they prevent fluid from bypassing the impeller chamber and stop air from entering the suction side of the pump. When an O-Ring ages, flattens, or cracks, the pump may struggle to hold prime, deliver consistent flow, or build adequate discharge pressure, making timely replacement essential to keeping the unit performing at full capacity.
