The Multiquip 65311 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. Verified against the original build specification, it is a direct fit for the listed ST-series submersible pump models with no adaptation required.
Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to the exact 50mm specification, ensuring proper stack height and internal clearance control critical to submersible pump performance.
- Direct-Fit Installation — Matches original hardware dimensions and seating geometry, dropping in exactly where the factory shim was installed.
- Confirmed ST-Series Compatibility — Verified fitment for ST41230, ST41460, ST61230, and ST61460 Multiquip submersible pumps.
- Maintains Correct Pump Alignment — Proper shimming keeps rotating components running true; a worn or missing shim can cause vibration, uneven wear, and premature bearing or seal failure.
- Genuine Multiquip OEM Part — Part 65311 is sourced directly from Multiquip, ensuring it meets the same material grade and thickness tolerance as the original component.
A shim is a thin precision spacer used to control the clearance and alignment between internal components inside a pump assembly. In a submersible pump, correct shimming ensures that rotating parts such as the impeller and shaft maintain the right running clearance, preventing metal-to-metal contact and uneven load distribution. When a shim wears down, is lost during service, or is replaced with an incorrectly sized substitute, it can lead to increased vibration, accelerated bearing wear, and reduced pump efficiency or output.
