The Multiquip 18035 Liner Ring is a genuine OEM component designed for QP and QPT series centrifugal pumps — including the QP205SH, QP205SLT, QP305SLT, QPT205SLT, and QPT305SLT — as well as WBH series power buggies including WBH-16, WBH-16E, WBH-16EF, WBH-16F, WBH-16EAWD, WBH-16EAWDF, WBH-21EF, WBH-21EFP, and WBH21EPA. As a direct Multiquip OEM part, the 18035 is manufactured to the same specification as the original, ensuring a correct fit without modification. Sourcing a genuine OEM liner ring means you're restoring the hydraulic clearances and wear surfaces the machine was engineered around, keeping fluid performance where it needs to be.
Key Features
- Genuine OEM Wear Tolerance — Manufactured to Multiquip's original dimensional specification, maintaining the tight clearances between the impeller and housing that determine pumping efficiency.
- Direct Drop-In Replacement — Engineered to the same profile as the original 18035 liner ring, seating correctly in the pump casing without rework or shimming.
- Broad Fitment Coverage — Confirmed fitment across QP205SH, QP205SLT, QP305SLT, QPT205SLT, QPT305SLT centrifugal pumps, and WBH-16 and WBH-21 series power buggies.
- Restores Flow Rate and Pressure — A worn liner ring allows fluid to recirculate back past the impeller, cutting output pressure and volume; replacing it restores the pump's rated performance.
- Fluid System Integrity — The liner ring forms a critical seal boundary inside the pump casing; a cracked or excessively worn ring can lead to cavitation, accelerated impeller wear, and unplanned stops on the job.
The liner ring sits inside the pump casing, forming a close-clearance boundary around the impeller. Its job is to minimize internal fluid bypass — the recirculation of pumped liquid back from the high-pressure discharge side to the low-pressure suction side. When this clearance is correctly maintained, the pump delivers its rated flow and head pressure. As the liner ring wears, that gap opens up, fluid slips back past the impeller, output drops, and the pump works harder than it should. Replacing a worn liner ring with a genuine Multiquip OEM part restores original hydraulic efficiency and protects the impeller and casing from the accelerated wear that follows unchecked bypass.
