The Wacker Neuson Nut is a genuine OEM component designed for the PT3 series 75mm/3in centrifugal trash pumps. As a factory-sourced part, it meets the exact specifications set by Wacker Neuson, ensuring a correct fit within the pump assembly. Compatible models include the PT3Y, PT3V, PT3A, PTK3, and PT3B — covering the full range of 3-inch centrifugal trash pump configurations in the PT3 lineup.

Key Features
- Genuine OEM Specification — Manufactured to Wacker Neuson's exact thread pitch and material grade, ensuring the nut seats and torques correctly within the pump assembly without risk of stripping or misfit.
- Drop-In Replacement — Engineered to the same dimensions as the original hardware, this nut installs directly into existing mounting points on PT3 series pumps with no rework needed.
- Broad PT3 Series Coverage — Fits the PT3Y, PT3V, PT3A, PTK3, and PT3B models, making it a single-part solution across the 75mm/3in centrifugal trash pump family.
- Maintains Pump Integrity — A correctly fastened nut keeps critical pump components securely in place under continuous vibration and high-flow operation, preventing loosening that can lead to leaks or component damage.
- Verified Wacker Neuson Part Number — Sourced and listed under OEM part number 5000077808, so you can order with confidence that you are receiving the correct hardware for your machine.
A nut may be a small piece of hardware, but in a high-vibration, high-flow application like a centrifugal trash pump, the integrity of every fastener matters. On PT3 series pumps, nuts are used throughout the assembly to secure housings, impeller components, and structural connections that must remain tight during continuous pumping operation. When a nut becomes corroded, stripped, or lost, the fastening point it holds can work loose — leading to misalignment, fluid leaks, or accelerated wear on surrounding components. Replacing worn or damaged hardware with the correct OEM part keeps the pump running as intended and helps protect the surrounding components it secures.
