Wacker Neuson 5000117819 Carbon/Ceramic Mechanical Seal

The Wacker Neuson Carbon/Ceramic Mechanical Seal is a genuine OEM component designed for the PT3 series 75mm/3-inch self-priming centrifugal trash pumps, including PT3, PT3A, PT3H, and PT3V models. As a direct OEM replacement, this seal is manufactured to the same specifications as the original, ensuring a correct fit and consistent sealing performance across the full PT3 family. Whether you are servicing a PT3A, PT3H, or PT3V variant, part number is the authorized replacement that restores your pump to proper operating condition. Keep a spare on hand for planned maintenance or emergency repairs to avoid unplanned downtime on the job.

Key Features

• Carbon/Ceramic Material Pairing — Hard-wearing ceramic seat combined with a carbon rotating face delivers low-friction sealing performance suited to continuous pump operation in abrasive slurry and dirty water conditions.
• Genuine OEM Part — Sourced directly from Wacker Neuson and manufactured to original engineering tolerances, so sealing face geometry and spring compression match the pump housing exactly as designed.
• Broad PT3 Series Compatibility — Confirmed fitment across PT3, PT3A, PT3H, and PT3V models, covering the full range of Wacker Neuson 75mm/3-inch centrifugal trash pump configurations.
• Prevents Pump Leakage at the Shaft — A correctly seated mechanical seal isolates the pumped fluid from the bearing housing and engine, preventing shaft leakage that leads to bearing failure and engine contamination.
• Drop-In Service Replacement — Installs in the same mechanical seal pocket as the original, with matching drive lugs and seat bore dimensions — no machining or adaptation needed during a standard pump service.

The mechanical seal in a centrifugal trash pump sits at the point where the impeller shaft passes through the pump volute. Its job is to maintain a watertight barrier between the wet end of the pump and the dry bearing and engine assembly. It does this through two precision-lapped sealing faces — one stationary, one rotating with the shaft — held in contact by a spring. When the carbon or ceramic faces wear, chip, or lose their spring tension, the seal fails and water begins to leak along the shaft, which quickly damages bearings and contaminates engine oil. Replacing the 5000117819 Carbon/Ceramic Mechanical Seal at the first sign of shaft weeping restores the pump's integrity and protects the drivetrain from secondary damage.
