The Multiquip 0852834525 Adjust Liner F45XF25.4 T0.3 is a genuine OEM component designed for Multiquip QP-series trash pumps and centrifugal pumps including QP4TB, QP3TB, QP3TS, QP3THX, QP4TK, QP4TKT, QP3TK, QP2TK, QP4TZ, QP3TH, QP4TH, QP3TZ, QP402H, and QP402B. As a direct OEM replacement, this liner is manufactured to the same dimensional and material standards as the original, ensuring it seats and seals correctly without rework. Sourced directly from Multiquip, part 0852834525 gives you confidence that you are installing the exact component the pump was engineered to run with. Verify your model against the fitment list above before ordering to confirm compatibility.
Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to the original F45XF25.4 T0.3 specification, ensuring the liner maintains the correct clearance tolerances critical to pump volumetric efficiency.
- Drop-In Replacement — Matches the original mounting profile and liner geometry so it installs directly into the pump volute without machining or fitting adjustments.
- Broad QP-Series Compatibility — Confirmed fitment across QP4TB, QP3TB, QP4TH, QP3TH, QP4TK, QP3TK, QP2TK, QP4TZ, QP3TZ, QP3TS, QP3THX, QP4TKT, QP402H, and QP402B models.
- Restores Pumping Performance — A worn or oversized liner gap allows water to recirculate internally, cutting flow rate and pressure; replacing with 0852834525 brings clearances back to spec and restores full output.
- Genuine Multiquip OEM Part — Supplied by an authorized Multiquip distributor, this is the same part used in original production, not a generic substitute.
The adjust liner is a precision wear component fitted inside the pump casing that controls the running clearance between the impeller and the volute wall. By maintaining a tight, consistent gap, it maximizes the hydraulic seal within the pump and ensures water is moved efficiently toward the discharge port rather than recirculating back to the inlet. As the liner wears over time, that clearance opens up, causing a noticeable drop in flow rate, reduced discharge pressure, and increased load on the engine — replacing it with a correctly sized liner like the Multiquip 0852834525 restores the pump to its original performance envelope.
