The Multiquip 6531150 Shim 50mm is a genuine OEM component designed for ST41230, ST41460, ST61230, and ST61460 submersible pumps. Sourced directly from Multiquip, this shim delivers the precise dimensional tolerancing required to maintain correct internal clearances and alignment within the pump assembly. It is a direct-fit replacement verified for compatibility across the ST4 and ST6 submersible pump series sold under the Multiquip portfolio.
Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to exact 50mm thickness and material specifications, ensuring correct load distribution and stack height within the pump assembly.
- Direct Drop-In Fit — Engineered to seat correctly in the pump assembly without modification, maintaining the alignment geometry the machine was designed around.
- Broad ST-Series Coverage — Compatible with ST41230, ST41460, ST61230, and ST61460 submersible pump models, covering both the ST4 and ST6 pump families.
- Preserves Internal Clearances — A correctly sized shim keeps rotating and stationary components properly spaced, preventing premature wear on bearings, seals, and impeller surfaces.
- Genuine Multiquip OEM Part — Supplied as an authorized OEM replacement, so part number 6531150 matches Multiquip's own service documentation and parts lists.
A shim is a precisely manufactured spacer used to set and maintain the correct clearance or alignment between two mating components inside the pump. In a submersible pump, proper shimming ensures the impeller and shaft assembly run at the intended axial position, preventing contact with the pump housing and keeping bearing loads within their designed range. When a shim is worn, deformed, or incorrectly sized, internal clearances shift — leading to accelerated bearing wear, vibration, reduced pumping efficiency, and potential seal failure.
