Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component it replaces. The Knob is a straightforward drop-in replacement, ensuring correct fit and function across the wide range of compatible pump models listed above. Whether you're servicing a single unit or maintaining a fleet of trash pumps, this genuine OEM part keeps your equipment operating to original specification.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the knob functions and feels identical to the factory-installed part.
- Direct-Fit Replacement — Engineered to seat and secure exactly as the original, with no trimming, drilling, or modification needed for installation.
- Broad Pump Family Coverage — Compatible with PTS4V, PT2A, PT2B, PT2R, PT2Y, PT3A, PT3B, PT3V, PT3Y, PTS4V(I), PTK2, PTK3, and PTK4 trash pump models, covering 2-inch, 3-inch, and 4-inch discharge configurations.
- Maintains Operator Control — A correctly functioning knob provides secure, positive grip for adjustments and shutoffs; a worn or damaged knob can make critical pump controls difficult to operate under field conditions.
- Verified Part Number — Part number 5000030146 is confirmed against Wacker Neuson's official parts documentation, giving you confidence you're ordering the correct component the first time.
A knob serves as the operator interface for a specific control or adjustment point on the pump — typically used to open, close, or position a valve, throttle, or similar mechanism by hand. While small, this component plays a direct role in day-to-day pump operation; if the knob cracks, strips, or breaks free from its shaft, the operator loses the ability to make quick, accurate adjustments in the field. Replacing a worn or damaged knob promptly ensures that pump controls remain accessible, responsive, and safe to use throughout the job.
