The Wacker Neuson is a genuine OEM Grease Fitting designed for the PDT2, PDT3, PDI2, and PDI3 series diaphragm trash pumps. Sourced directly from Wacker Neuson, this fitting carries the exact specifications required for proper lubrication point compatibility across the full range of 50mm/2-inch and 75mm/3-inch diaphragm pump models. Fitment covers a broad selection of PDT and PDI variants, including inline and standard configurations in both A and B sub-series. Keeping the correct OEM fitting in place ensures the lubrication system performs as intended and protects pump components from premature wear.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's exact thread pitch and seating geometry, ensuring a secure, leak-free connection at every grease point.
- Direct-Fit Replacement — Matches the original fitting profile, threading directly into existing ports without rework or adapter hardware.
- Broad PDT and PDI Compatibility — Fits PDT2, PDT2A, PDT2B, PDT3, PDT3A, PDI2, PDI2A, PDI3, and PDI3A diaphragm trash pump series in both 50mm/2-inch and 75mm/3-inch discharge sizes.
- Lubrication Integrity — A correctly seated grease fitting allows controlled grease delivery to pump bearings and moving assemblies, preventing dry running and component seizure.
- Verified OEM Part Number — Part number 5002005636 cross-references directly to Wacker Neuson's parts catalog, confirming you receive the right component for your specific pump model.
A grease fitting — sometimes called a Zerk fitting — is the access point through which grease is injected into a machine's lubrication passages using a grease gun. On diaphragm trash pumps like the Wacker Neuson PDT and PDI series, these fittings serve bearing housings and pivot points that require periodic lubrication to function correctly. When a fitting is damaged, stripped, or missing, grease cannot reach critical internal surfaces, accelerating wear on bearings and drive components and ultimately leading to pump failure. Replacing a worn or compromised fitting promptly restores the lubrication pathway and keeps the pump operating through demanding fluid-transfer applications.
