Wacker Neuson 5100067176 Rotary Shaft Seal

The Wacker Neuson Rotary Shaft Seal is a genuine OEM rotary shaft seal designed for BPS1550B, BPS2050B, and A5000/160B series submersible pumps. Sourced directly from Wacker Neuson, this part carries the same material grade and dimensional spec as the seal originally installed at the factory. It fits both standard and "w" variants of the BPS1550B and BPS2050B, covering a broad range of configurations in the BPS series lineup. When your existing seal shows signs of leakage or wear, replacing it with part number restores the integrity of the shaft interface and keeps pump performance where it needs to be.

Key Features

• OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original compound and compression specification, ensuring the seal seats and loads correctly against the rotating shaft.
• Drop-In Replacement — Matches the exact bore diameter, outer diameter, and lip profile of the original, so installation follows the standard service procedure without modification.
• Broad BPS and A5000 Series Coverage — Confirmed fitment for BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B submersible pump models.
• Prevents Fluid Ingress and Shaft Wear — A healthy rotary shaft seal keeps water and abrasive particles away from internal bearings and the motor cavity; a worn seal accelerates shaft scoring and can lead to motor failure.
• Genuine OEM Part — Supplied under Wacker Neuson part number 5100067176, giving you full traceability and confidence in fitment accuracy before the part ships.

A rotary shaft seal forms a dynamic barrier between a spinning shaft and the stationary housing around it. In a submersible pump, it sits at the point where the drive shaft exits the motor and enters the pump casing, blocking water, slurry, and debris from migrating into the motor cavity along the shaft. As the seal wears, the lip loses its tension against the shaft surface, allowing fluid to bypass the barrier — leading to motor winding damage, bearing corrosion, and ultimately pump failure. Replacing the seal at the first sign of leakage is one of the most cost-effective ways to extend the service life of the pump.
