The Wacker Neuson is a genuine OEM Oil Lifter designed for the PS4-7503HH, PS4-7503HF, PS4-11003HH, PS4-11003HF, PSC42203, and PSC42303EX submersible pump series. As a direct Wacker Neuson OEM component, part is manufactured to the same tolerances and material standards as the original, ensuring proper lubrication circulation within the pump motor assembly. This Oil Lifter fits across a wide range of PS4 and PSC4 series configurations, covering high-head and high-flow variants operating on 220V, 440V, and 400V power supplies. Confirm your pump's model number before ordering to ensure full compatibility.
Key Features
- Genuine OEM Lubrication Integrity — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring consistent oil circulation and film protection across the motor's rotating components.
- Drop-In Installation — Designed to seat and function exactly as the factory-installed unit, with no modifications to the pump housing or motor assembly required.
- Broad PS4 and PSC4 Series Coverage — Compatible with PS4-7503HH, PS4-7503HF, PS4-11003HH, PS4-11003HF, PSC42203, and PSC42303EX submersible pumps across multiple voltage configurations.
- Protects Motor Longevity — A functioning Oil Lifter keeps critical internal surfaces lubricated under load; a failed or worn lifter accelerates bearing and seal wear, leading to motor failure in submerged applications.
- Verified OEM Part Number — Cross-reference 5000176979 against your pump's parts diagram to confirm fitment before installation.
The Oil Lifter is an internal pump component responsible for circulating lubrication oil within the motor housing of a submersible pump. As the pump operates, the lifter draws oil upward to coat and protect the motor's bearings and rotating shaft surfaces, preventing metal-to-metal contact during continuous submerged operation. When the Oil Lifter wears or fails, lubrication to the motor internals becomes inconsistent, accelerating bearing wear and increasing the risk of motor seizure or premature failure — particularly under the sustained duty cycles typical of dewatering and construction site pump applications.
