Multiquip 511839 Base Shim 1.0 MM

The Multiquip 511839 Base Shim 1.0 MM is a genuine OEM shim designed for MQ600H series trash pumps, including the MQ600H, MQ600HTB, MQ600HTP, MQ600TD80-TLRB, and MQ600TD80-TLRP. Sourced directly from Multiquip, this 1.0 mm shim restores the precise tolerances needed to keep the pump assembly running true. If you are servicing your MQ600 series pump, using the correct OEM shim ensures the original clearance specs are maintained without guesswork.

Key Features

• Exact 1.0 MM Thickness: — Machined to a specific 1.0 mm dimension so the correct base clearance is restored during reassembly.
• Genuine OEM Construction: — Manufactured to Multiquip's original material and dimensional specifications, ensuring consistent fit within the pump base assembly.
• Direct Replacement for MQ600 Series: — Confirmed fitment for MQ600H, MQ600HTB, MQ600HTP, MQ600TD80-TLRB, and MQ600TD80-TLRP trash pumps.
• Critical Alignment Component: — Proper shim thickness prevents shaft and impeller misalignment that can accelerate wear on seals and bearings.
• Supports Accurate Pump Rebuild: — Using the correct shim thickness during a pump overhaul ensures internal components seat and load correctly for full service life.

A base shim is a precision-thickness spacer installed within the pump assembly to set and maintain the correct clearance between internal components. In a trash pump, even a small deviation in this clearance can cause uneven loading on the impeller, premature seal wear, or vibration during operation. Using a shim of the correct thickness — in this case 1.0 mm — is essential when rebuilding or reassembling the pump to restore it to its original operating condition.
