The Wacker Neuson Bearing Housing is a genuine OEM component designed for the PS3-5503 and PS4-5503 series submersible pumps. As a direct OEM replacement, this part is manufactured to the same standards as the original, ensuring a correct, reliable fit within the pump assembly. Compatible across a wide range of PS3-5503 and PS4-5503 configurations — including 220V, 440V, 575V, and 400V/50Hz variants — this housing covers both 75mm/3-inch and 100mm/4-inch discharge models. Confirming your machine number against the fitment list before ordering is recommended.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original dimensional and material specifications, ensuring the bearing seats and housing tolerances match what the pump was built with.
- Direct Drop-In Replacement — Machined to align with the existing motor and pump shaft arrangement in PS3-5503 and PS4-5503 assemblies, fitting into the pump stack without rework.
- Broad Voltage Compatibility — Covers 220V/60Hz, 440V/60Hz, 575V/60Hz, and 400V/50Hz pump configurations across both the PS3 and PS4 model families.
- Supports Pump Shaft Alignment — A correctly fitted bearing housing maintains precise shaft concentricity, which is critical for smooth impeller rotation and preventing premature seal or bearing wear.
- Verified OEM Part Number — Part number 5000150618 is the authorized Wacker Neuson reference for this housing across the listed PS-series submersible pump variants.
The bearing housing is a structural component that encases and positions the pump's bearings, holding them in precise alignment relative to the motor shaft. It acts as the load-bearing interface between the rotating shaft assembly and the pump body, keeping the impeller centered and the shaft stable under the hydraulic and mechanical forces generated during pumping. When this housing is cracked, corroded, or worn out of tolerance, bearings shift out of position — leading to shaft wobble, accelerated seal failure, and eventual pump seizure. Replacing a damaged housing promptly restores proper shaft support and protects the surrounding drivetrain components from secondary damage.
