Multiquip 511244 Impeller Shim Kit

The Multiquip 511244 Impeller Shim Kit is a genuine OEM component designed for MQ600TD80-TLRB, MQ600TD80-TLRP, MQ600H, MQ600HTB, and MQ600HTP series trash pumps. As a direct OEM part, 511244 meets the exact tolerances required to properly set impeller clearance on these high-volume pumping units. Sourced directly through Multiquip's authorized parts network, this shim kit ensures the impeller is positioned correctly within the pump housing for optimal flow and pressure output. If you're servicing any of the MQ600 trash pump family, this is the correct kit to have on hand.

Key Features

• OEM-Exact Shim Thickness: — Each shim is manufactured to the precise dimensional spec required for correct impeller clearance in MQ600 series trash pumps — not a close approximation.
• Drop-In Fitment for MQ600 Trash Pumps: — Engineered specifically for the MQ600TD80-TLRB, MQ600TD80-TLRP, MQ600H, MQ600HTB, and MQ600HTP — installs without rework or custom fitting.
• Restores Pumping Efficiency: — Correct impeller spacing directly affects flow rate and suction lift; this kit brings clearance back to spec so the pump moves material the way it was designed to.
• Genuine Multiquip OEM Part: — Part number 511244 is sourced from Multiquip's authorized supply chain, so you're getting the same component that shipped with the machine originally.
• Kit Format for Full Service: — Supplied as a complete shim kit, giving you the material needed to set clearance correctly in a single service event without hunting for individual shims.

The impeller shim kit controls the axial clearance between the pump impeller and the volute housing. When this gap is too large, the pump loses suction efficiency and struggles to prime or move thick slurry and debris-laden water. When the gap is too tight, the impeller can contact the housing and cause rapid wear or mechanical damage. During a pump rebuild or impeller replacement, shimming restores that clearance to the manufacturer's specification — a step that directly determines whether the pump performs at full capacity or underperforms from the first use. Using the correct shim kit, like the Multiquip 511244, ensures the adjustment is made with components matched to the original design of the MQ600 trash pump series.
