The Multiquip 0458220080 is a genuine OEM Spring Washer (Impeller) M8 designed for Multiquip QP-series trash pumps and centrifugal pumps, including QP2TH, QP3TH, QP2TK, QP3TK, QP2TZ, QP3TZ, QP3TB, QP2TB, QP402H, QP402B, QPT305SLT, QPT205SLT, QP305SLT, and QP205SLT models. As a direct OEM replacement, 0458220080 meets the exact material and dimensional specifications set at the factory, ensuring the impeller assembly seats and functions as intended. Sourced directly through Multiquip's authorized parts network, this washer is the correct choice when servicing or rebuilding the impeller on any compatible QP-series unit.
Key Features
- OEM-Grade Spring Tension: — Manufactured to the exact compression and spring-rate specification required to properly secure the M8 impeller stack — no guessing on fitment or load tolerance.
- Drop-In Impeller Compatibility: — Designed to install directly onto the impeller shaft in QP-series pump assemblies without modification to the surrounding hardware.
- Broad QP-Series Coverage: — Confirmed fit across QP2TH, QP3TH, QP2TK, QP3TK, QP2TZ, QP3TZ, QP3TB, QP2TB, QP402H, QP402B, QPT305SLT, QPT205SLT, QP305SLT, and QP205SLT pump models.
- Impeller Retention Performance: — A correctly tensioned spring washer keeps the impeller locked at the proper axial position, maintaining pump efficiency and flow rate. A worn or omitted washer allows impeller movement that degrades output and accelerates wear on the volute.
- Genuine Multiquip OEM Part: — Supplied as a factory-sourced component, not a generic substitute, so you can be confident the part matches the original specification for your pump model.
A spring washer at the impeller position serves a straightforward but critical role: it applies consistent axial preload to hold the impeller firmly in place on the pump shaft. Without that tension, the impeller can shift under load, reducing hydraulic efficiency and creating metal-to-metal contact that wears internal pump components prematurely. Replacing a fatigued or damaged spring washer during pump servicing restores the correct clamping force and protects the broader impeller assembly from unnecessary wear.
