Multiquip 17420 Shim Kit Vacuum Pump Impeller

The Multiquip 17420 is a genuine OEM Shim Kit Vacuum Pump Impeller designed for the MP200 Series masonry saws. As a direct OEM replacement, this shim kit delivers the exact tolerancing needed to properly set impeller clearance within the vacuum pump assembly. Correct shimming is critical to maintaining consistent water flow and vacuum pump efficiency — making this kit an essential service component during any pump rebuild or maintenance interval on MP200 Series equipment.

Key Features

• Exact Impeller Clearance Specification — Genuine OEM shim stack machined to the precise thickness tolerances required for correct vacuum pump impeller positioning.
• Direct Service Replacement — Installs directly into the vacuum pump assembly on MP200 Series masonry saws without modification to surrounding components.
• MP200 Series Fitment — Confirmed compatibility with Multiquip MP200 Series masonry saw models.
• Preserves Water Delivery Performance — Properly shimmed impeller clearance maintains optimal vacuum pump output, ensuring consistent water flow to the blade during cutting operations.
• Rebuild-Ready Component — Packaged as a complete shim kit so technicians have the correct selection of shims on hand when servicing or rebuilding the vacuum pump assembly.

The vacuum pump impeller shim kit controls the axial clearance between the impeller and the pump housing. When clearance is too loose or too tight, the pump loses efficiency — resulting in reduced water flow to the blade, which can cause overheating and premature blade wear. Using the correct OEM shim kit during service ensures the impeller runs at the designed operating clearance, restoring full pump performance and protecting downstream components.
