The Multiquip 2750343005 is a genuine OEM Lock Washer M6 ST41230 designed for MQ submersible clean water pump equipment. As a factory-sourced component, it is manufactured to the exact material and dimensional specifications required for proper fastener retention in Multiquip submersible pump assemblies. This washer is a direct-fit replacement for ST41230 series machines, ensuring correct installation without guesswork. DHS Equipment stocks this part to keep your pump running with the hardware it was built around.
Key Features
- Genuine OEM Hardware Grade — Manufactured to Multiquip's material and hardness specifications for an M6 lock washer, ensuring correct clamping force and corrosion resistance in wet pump environments.
- Drop-In Replacement — Matches the original M6 thread pitch and outer profile exactly, seating flush against fastener and mating surface without shimming or modification.
- Confirmed Fitment for ST41230 Series — Sourced and validated for MQ submersible clean water pump applications within the ST41230 equipment family.
- Fastener Integrity Under Load — A functioning lock washer prevents bolt and nut loosening caused by vibration during pump operation; a worn or missing washer risks fastener walk-off and component separation.
- Submersible Environment Ready — Selected to withstand the moisture-rich, submerged operating conditions common to clean water pump installations.
A lock washer is a small but critical piece of hardware placed beneath a nut or bolt head to resist loosening caused by vibration, torque fluctuation, or thermal cycling. In submersible pump assemblies, where components are subject to continuous vibration from the motor and impeller, a properly seated lock washer maintains fastener clamp load and prevents unwanted movement between assembled parts. When a lock washer fails, flattens, or goes missing, fasteners can back out over time — leading to misalignment, leaks, or structural loosening that affects pump performance and service life.
