The Multiquip 1803521220 Liner Ring is a genuine OEM component designed for the QP205SLT, QP305SLT, QPT205SLT, QPT305SLT, and QP205SH centrifugal pump series. Sourced directly through Multiquip's authorized parts program, this liner ring meets the exact material and dimensional specifications of the original factory component. Cross-reference part number 1803521220 before ordering to confirm compatibility with your specific pump model.
Key Features
- Genuine OEM Material Match — Manufactured to the same wear-resistant material grade as the original, maintaining the tight clearances that centrifugal pump efficiency depends on.
- Direct Drop-In Fitment — Engineered to seat precisely within the pump volute housing, allowing straightforward replacement without custom fitting or machining.
- Broad Pump Series Coverage — Confirmed fit for QP205SLT, QP305SLT, QPT205SLT, QPT305SLT, and QP205SH centrifugal pumps.
- Sustained Flow Performance — A correctly seated liner ring maintains the critical clearance between the impeller and housing; a worn ring causes pressure drop, reduced flow rate, and increased pump strain.
- OEM Parts Program Sourced — Supplied as a genuine Multiquip replacement, ensuring the part meets the same quality controls applied to production units.
The liner ring sits inside the pump casing and surrounds the outer edge of the impeller, creating a controlled seal that directs water efficiently through the pump and maintains pressure. As the clearance between the liner ring and impeller is critical to pump output, a worn or damaged ring allows fluid to recirculate back toward the inlet rather than moving through the discharge — resulting in lost pressure, reduced flow, and increased wear on surrounding components. Replacing the liner ring at the first sign of performance loss restores the pump to its designed output capacity and protects the impeller and volute from accelerated damage.
