Multiquip 511838 Base Shim 0.5 MM

The Multiquip 511838 is a genuine OEM Base Shim 0.5 MM designed for MQ600 series trash pumps, including the MQ600TD80-TLRB, MQ600TD80-TLRP, MQ600H, MQ600HTB, and MQ600HTP. As a factory-original component sourced directly through Multiquip, 511838 delivers the exact thickness tolerance required to maintain proper component alignment within the pump assembly. DHS Equipment supplies this part as a direct OEM replacement, giving you confidence that the shim you install matches the original specification. If you are servicing any of the MQ600 series units listed above, 511838 is the correct part to restore your pump to proper operating clearance.

Key Features

• Exact OEM Thickness Tolerance — Manufactured to the precise 0.5 MM specification, ensuring correct component spacing and alignment within the pump housing.
• Genuine Multiquip OEM Part — Factory-original construction means this shim meets the same material and dimensional standards as the part that left the production line.
• Confirmed MQ600 Series Fitment — Verified compatibility with MQ600TD80-TLRB, MQ600TD80-TLRP, MQ600H, MQ600HTB, and MQ600HTP trash pumps.
• Drop-In Installation — Matches the original shim profile for straightforward installation during routine service or pump rebuilds without additional machining.
• Protects Pump Longevity — Correct base clearance prevents uneven wear on rotating components, helping the pump maintain flow performance and avoid premature failure.

A base shim is a precision spacer used to set and maintain the correct clearance between mating components within the pump assembly. In a trash pump, maintaining exact tolerances at the base is critical — even a small deviation in spacing can cause misalignment of the impeller or shaft, leading to vibration, accelerated wear, and loss of pumping efficiency. When a shim is worn, damaged, or replaced with an incorrect thickness, the assembly cannot hold proper clearance, which shortens the service life of surrounding components and ultimately compromises pump output.
