The Multiquip 0489242100 is a genuine OEM O-Ring Dia 2.4 x Dia. 210 (Casing) designed for QP2B and QP2H centrifugal pumps. As a direct Multiquip OEM component, 0489242100 meets the exact material and dimensional specifications required for a proper casing seal. This o-ring is confirmed to fit QP2B and QP2H series pumps, making it a straightforward service part for routine maintenance or leak repair. Order from DHS Equipment for fast fulfillment of genuine Multiquip replacement parts.
Key Features
- Genuine OEM Sealing Material — Manufactured to Multiquip's exact compound and durometer specification, ensuring the casing o-ring maintains a consistent, pressure-holding seal under pump operating conditions.
- Correct Casing Groove Dimensions — Sized precisely at Dia. 2.4 x Dia. 210 to seat flush in the pump casing groove without stretching or compression distortion during reassembly.
- Confirmed Fitment for QP2B and QP2H — Verified compatibility with QP2B and QP2H centrifugal pumps, so you can order with confidence and avoid costly cross-part errors.
- Leak Prevention at the Casing Joint — A correctly seated casing o-ring maintains prime and discharge pressure; a worn or damaged o-ring causes air ingestion, loss of prime, and reduced flow output.
- Fluid-System Safety — On centrifugal dewatering pumps, a failed casing seal can allow uncontrolled fluid bypass and pump cavitation — replacing with a genuine OEM o-ring restores safe, controlled fluid handling.
The casing o-ring on a centrifugal pump forms the primary static seal between the pump casing halves or between the casing and volute cover, preventing water from bypassing the impeller and escaping the pressurized fluid path. When this o-ring degrades — through age, chemical exposure, or repeated thermal cycling — the pump loses its ability to hold prime, discharge pressure drops, and the unit may draw air rather than fluid. Replacing the o-ring at the first sign of weeping or loss of prime restores full pumping efficiency and protects the surrounding casing surfaces from moisture-related wear.
