The Wacker Neuson Lip Seal is a genuine OEM component designed for the PDT2, PDT3, PDI2, and PDI3 series diaphragm trash pumps. Sourced directly from Wacker Neuson, this lip seal meets the exact material and dimensional specifications of the original part — ensuring a proper sealing interface within the pump assembly. It fits both the standard diaphragm (PDT) and inline diaphragm (PDI) configurations in 50mm/2-inch and 75mm/3-inch discharge sizes. When the factory-matched seal is in place, you can count on consistent fluid containment and full pump performance across the entire PDT and PDI lineup.
Key Features
- OEM Sealing Material Match — Manufactured to the original compound and hardness specification, ensuring correct lip compression and fluid containment under pump operating pressures.
- Drop-In Fitment for PDT and PDI Pumps — Seats directly into the original bore without modification, maintaining the sealing geometry the pump housing was engineered around.
- Broad Series Coverage — Fits PDT2, PDT2A, PDT3, PDT3A, PDI2, PDI2A, PDI3, and PDI3A diaphragm trash pumps in both 50mm/2-inch and 75mm/3-inch discharge configurations.
- Prevents Fluid Bypass and Leakage — A worn or hardened lip seal allows fluid to migrate past the shaft or housing interface, causing loss of prime, reduced output, and contamination of surrounding components.
- Fuel and Fluid System Integrity — Correct lip seal specification is critical in pump assemblies where fluid contact with mechanical components can cause accelerated wear or unsafe operating conditions.
A lip seal creates a dynamic, flexible barrier between rotating or reciprocating components and the pump housing, preventing fluid from escaping the wet end of the pump while keeping contaminants out of the mechanical assembly. In diaphragm trash pumps like the PDT and PDI series, maintaining this seal is essential to sustaining prime and achieving rated flow — a degraded or improperly sized seal will allow bypass, leading to reduced discharge pressure and potential dry-running of internal components. Replacing a worn lip seal at the first sign of leakage protects the broader pump assembly and restores full pumping capacity.
