The Wacker Neuson Oil Seal is a genuine OEM component designed for the PDT2A, PDT2, PDT3A, PDT3, PDI2A(I), PDI3A, and PDI3A(I) series diaphragm pumps. Sourced directly from Wacker Neuson, this seal meets the exact material and dimensional specifications of the original part installed at the factory. It fits across both the PDT and PDI diaphragm pump families, covering the full range of 2-inch and 3-inch discharge configurations in this line. If your pump is showing signs of fluid weeping, oil contamination, or seal degradation, part number is the correct direct replacement to restore proper operation.
Key Features
- OEM-Grade Sealing Material — Manufactured to the same compound and compression tolerances as the original, ensuring a consistent fluid-tight barrier under pump operating pressures.
- Drop-In Replacement — Matches the original seal profile and bore dimensions on PDT and PDI series pumps, seating correctly into the existing housing without rework.
- Broad Diaphragm Pump Coverage — A single part number covers PDT2A, PDT2, PDT3A, PDT3, PDI2A(I), PDI3A, and PDI3A(I) models, simplifying parts sourcing across your pump fleet.
- Prevents Oil Migration and Cross-Contamination — A sound oil seal keeps lubricating oil contained within its designated cavity, protecting diaphragm components from oil contamination and maintaining pump output efficiency.
- Fuel and Fluid System Integrity — Maintaining an intact oil seal is essential to preventing hazardous fluid leaks and keeping the pump running within its intended operating parameters.
An oil seal serves as the barrier between rotating or reciprocating shaft surfaces and the fluid or lubricant cavities within a pump. In diaphragm pumps like the PDT and PDI series, the oil seal prevents lubricating oil from migrating past the shaft into other chambers, which would compromise both lubrication effectiveness and pump output. When an oil seal wears, hardens, or becomes damaged, the result is typically visible leakage, accelerated internal wear, and eventual loss of pumping performance — making timely replacement critical to keeping the unit in service.
