The Multiquip 0481572500 is a genuine OEM Volute Casing O-Ring designed for QP4TH, QP4TZ, QP4TKT, QP4TB, and QP4TK series trash pumps. As a direct OEM component, 0481572500 is manufactured to the exact material grade and dimensional tolerances of the original part, ensuring a proper seal at the volute casing interface. This O-Ring is the correct replacement for any QP4T-series trash pump showing signs of leakage, weeping, or loss of prime around the casing joint. DHS Equipment supplies this genuine Multiquip part ready to ship so you can get your pump back in service fast.
Key Features
- OEM-Grade Elastomer Material — Manufactured to the original compound and durometer specification, delivering the compression and chemical resistance required for pump fluid sealing duty.
- Drop-In Casing Fit — Profiles match the volute casing groove exactly, seating without trimming or adjustment during reassembly.
- Broad QP4T Series Coverage — Confirmed fitment for QP4TH, QP4TZ, QP4TKT, QP4TB, and QP4TK trash pump models from Multiquip's quick-prime lineup.
- Leak-Free Prime Retention — A correctly seated volute casing O-Ring maintains the airtight seal the pump needs to self-prime and sustain discharge pressure; a cracked or flattened O-Ring causes immediate prime loss and output drop.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, carrying the same part number 0481572500 used in factory assembly and authorized service documentation.
The volute casing O-Ring creates a sealed joint between the pump's volute casing halves or between the casing and its mating cover, preventing air ingestion and fluid leakage at the pump's pressurized chamber. Without an intact seal at this interface, the pump cannot build or hold the prime needed to move water and solids efficiently, resulting in cavitation, reduced flow, and potential damage to the impeller and shaft seal. Replacing a worn or damaged O-Ring at the first sign of weeping around the casing joint is a simple, low-cost step that restores full pumping performance and protects the surrounding components.
