Key Features
- Genuine OEM Precision Housing — Manufactured to original Multiquip tolerances, ensuring the bearing seats and aligns correctly within the pump assembly.
- Direct Installation Fit — Mounts in the same position as the original lower housing, with matching bolt patterns and bore dimensions for a clean swap during service.
- Confirmed Fitment for ST6125D and ST4125D — Specifically validated for Multiquip ST6125D and ST4125D clean water submersible pump models.
- Protects Bearing Integrity Under Submersed Load — A sound lower bearing housing keeps the bearing properly seated and aligned, preventing lateral shaft movement that leads to accelerated wear and pump failure.
- Maintains Pump Efficiency — When the lower housing is intact and correctly aligned, the impeller runs true, preserving flow rate and reducing stress on the motor and shaft seal.
The lower bearing housing is a structural component that encloses and supports the lower bearing on the pump shaft. It holds the bearing in precise alignment so the shaft rotates smoothly under the hydraulic loads generated during pumping. When this housing cracks, corrodes, or wears, the bearing loses its support, causing shaft wobble that accelerates wear on the seal, impeller, and motor — ultimately leading to pump failure and potential ingress of water into the motor cavity.
