The Wacker Neuson Shaft Seal is a genuine OEM component designed for the PT2 series 50mm/2in centrifugal trash pumps. As a direct OEM replacement, this shaft seal is sourced and manufactured to Wacker Neuson's original specifications, ensuring the correct material grade and dimensional fit for a leak-free installation. Verified fitment covers the PT2Y, PT2A, PT2B, PT2R, and PTK2 pump models, making it the right choice for a wide range of PT2 series applications. When it's time to restore pump integrity, part number is the factory-correct solution.
Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's original material and compression specifications, delivering consistent sealing performance under the pressure and fluid contact conditions typical of trash pump operation.
- Drop-In Pump Shaft Fit — Engineered to seat correctly on the pump shaft bore without modification, maintaining proper alignment between the impeller and pump housing.
- Broad PT2 Series Coverage — Confirmed fitment across PT2Y, PT2A, PT2B, PT2R, and PTK2 50mm/2in centrifugal trash pump models, including engine-equipped and bare-pump (PTK2) configurations.
- Prevents Fluid Intrusion and Shaft Damage — A serviceable shaft seal stops water and debris from migrating along the pump shaft into the bearing and engine compartment, protecting surrounding components from accelerated wear.
- Genuine Wacker Neuson OEM Part — Supplied as an authorized OEM replacement under part number 5000070786, ensuring full traceability and compatibility with Wacker Neuson's parts documentation.
The shaft seal on a centrifugal trash pump creates a dynamic barrier between the rotating pump shaft and the pump housing, preventing water, slurry, and debris from escaping along the shaft and reaching the engine or bearing assembly. Over time, continuous shaft rotation and exposure to abrasive fluids cause the seal lip to wear, leading to visible leaks around the shaft, loss of prime, and potential bearing failure if left unaddressed. Replacing a worn shaft seal with the correct OEM part restores the pump's fluid containment and protects the drivetrain components it surrounds.
