New Style Mechanical Seal Kit | Wacker PT3, PT3A - Threaded Impeller | 0117819, 5000117819

The Wacker Neuson Carbon/Ceramic Mechanical Seal is a genuine OEM component designed for the PT3, PT3A, PT3H, and PT3V series 75mm/3-inch self-priming centrifugal trash pumps. As a direct OEM replacement, this seal is manufactured to the same specifications as the original, ensuring a correct, leak-free fit within the pump housing. It covers an extensive range of PT3-family machine numbers, making it the go-to seal for technicians servicing this pump series. Stock this part on the shelf and eliminate guesswork when a pump shaft seal fails in the field.

Key Features

• Carbon/Ceramic Face Materials — The carbon-on-ceramic face pairing delivers low friction and high wear resistance, keeping the seal interface tight through continuous pump operation in abrasive slurry and debris-laden water.
• Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, this seal meets the exact dimensional and material tolerances specified for PT3-series pump assemblies.
• Direct Drop-In Replacement — Engineered to seat correctly in the existing pump volute housing without machining or adaptation, allowing a straightforward seal swap during routine pump service.
• Broad PT3 Family Coverage — Fits PT3, PT3A, PT3H, and PT3V pump variants across a wide range of machine configurations, consolidating your parts inventory around a single seal number.
• Prevents Shaft Leakage and Pump Damage — A compromised mechanical seal allows water to migrate along the drive shaft into the bearing housing, leading to bearing failure and impeller damage. Replacing with 5000117819 restores a proper fluid barrier and protects downstream drivetrain components.
• Fluid Containment Integrity — Maintaining a sound mechanical seal is essential on job sites where pump discharge fluids must be contained — a leaking seal can create slip hazards and environmental compliance issues.

The mechanical seal in a centrifugal trash pump sits at the interface between the rotating pump shaft and the stationary pump casing, creating a pressurized fluid barrier that prevents pumped water from escaping along the shaft. On PT3-series pumps, the carbon/ceramic face construction handles the friction and heat generated by continuous shaft rotation while resisting wear from fine particulates suspended in the pumped fluid. When the seal faces wear, score, or crack, the pump will begin to leak at the shaft, which — if left unaddressed — allows moisture to reach the shaft bearings and cause progressive mechanical failure throughout the pump assembly.
