The Wacker Neuson Oil Plug is a genuine OEM component designed for the PS2, PSA2, PST2, PST3, PSTF2, PSTF3, PSW3, PSR1, PSG2, PSC3, and PS2-1500 series submersible pumps. As a direct OEM replacement, the is manufactured to the same specifications as the original part that left the factory, ensuring a correct, leak-free seal every time. This Oil Plug covers an extensive range of Wacker Neuson submersible pump configurations across multiple voltage variants — including 110V, 220V, and 230V models — making it a versatile stock item for service technicians and pump fleet operators alike. Confirm your model number against the fitment list before ordering to ensure this is the correct plug for your application.
Key Features
- Sealed to Specification: — Manufactured to OEM tolerances, this Oil Plug delivers a consistent, pressure-rated seal that prevents oil migration into the pump housing or surrounding water.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, part number 5000150535 is the same component used in original pump assembly — no substitutions or approximations.
- Broad Submersible Pump Compatibility: — Fits across the PS2, PSA2, PST2, PST3, PSTF2, PSTF3, PSW3, PSR1, PSG2, and PSC3 submersible pump families, spanning a wide range of voltage and capacity configurations.
- Drop-In Installation: — Designed to thread directly into the existing oil port on compatible Wacker Neuson submersible pumps, using the same thread pitch and seating geometry as the original plug.
- Protects Motor Oil Integrity: — A correctly seated oil plug keeps the pump's oil reservoir sealed during operation, maintaining proper lubrication of the motor bearings and mechanical seal — a worn or missing plug leads to oil loss and accelerated bearing failure.
- Critical Fluid Barrier: — In submersible applications, a failed or missing oil plug risks water intrusion into the oil chamber, which can cause rapid motor damage — making timely replacement of this small component essential to pump longevity.
The oil plug on a Wacker Neuson submersible pump seals the oil fill or drain port on the motor housing, keeping the lubricating oil that protects the motor's bearings and mechanical seal contained during operation. In submersible pumps, maintaining this seal is especially critical because any breach can allow water to contaminate the oil reservoir, rapidly degrading lubrication and leading to bearing seizure or mechanical seal failure. A cracked, stripped, or missing oil plug should be replaced immediately to avoid costly motor damage.
