The Wacker Neuson is a genuine OEM Oil Plug designed for the PS4-7503HH, PS4-7503HF, PS4-11003HH, and PS4-11003HF series submersible pumps. As a factory-authorized component, it meets the exact specifications required to maintain a proper oil seal in the pump motor housing. This Oil Plug fits across a broad range of PS4 series configurations, including high-head and high-output variants operating at voltages from 220V through 575V. Keeping this plug in good condition is essential to protecting the pump's motor oil from contamination and preventing lubricant loss during operation.
Key Features
- Genuine OEM Seal Integrity — Manufactured to Wacker Neuson's exact thread pitch and material specification, ensuring a leak-free oil chamber seal in the pump motor housing.
- Direct-Fit Replacement — Threads directly into the existing oil port on PS4-series pump motor housings with no modification to the housing or surrounding components.
- Broad PS4 Series Coverage — Compatible with PS4-7503HH, PS4-7503HF, PS4-11003HH, and PS4-11003HF models across 50Hz and 60Hz variants, as well as PSC4 series submersible pumps.
- Motor Protection — A correctly seated Oil Plug keeps the motor oil clean and at the right level, directly supporting bearing and seal longevity inside the submersible motor.
- Prevents Costly Oil Contamination — A damaged or missing oil plug allows water ingress into the motor oil chamber, which can lead to rapid bearing failure and motor burnout in submerged applications.
The Oil Plug seals the oil fill or drain port on the motor housing of a submersible pump. Submersible pump motors rely on an oil-filled chamber to lubricate and cool internal bearings and mechanical seals — without a properly sealed plug, that oil can leak out or become contaminated with the surrounding water. A failed or cross-threaded oil plug is one of the most common causes of premature motor failure in submersible pumps, making this a critical service item to inspect and replace during routine maintenance.
