The Wacker Neuson PT3 Housing is a genuine OEM component designed for the PT3, PT3A, and PT3H series 3-inch self-priming centrifugal trash pumps. As a direct OEM replacement, this housing is manufactured to the same specifications as the original part, ensuring a correct, trouble-free installation. It is compatible across a wide range of PT3 pump configurations, including the PT3A 75mm/3-inch centrifugal trash pump and the PT3H variants. Verify your machine number against the fitment list to confirm compatibility before ordering.
Key Features
- Genuine OEM Construction: — Manufactured to the same structural and dimensional tolerances as the original pump housing, maintaining correct volute geometry and port alignment for consistent flow performance.
- Direct-Fit Replacement: — Mounts to the existing pump assembly using the original bolt pattern and port configuration, requiring no modification to surrounding components.
- Broad PT3 Series Compatibility: — Confirmed fitment across PT3, PT3A, and PT3H pump models, covering multiple machine numbers within the Wacker Neuson 3-inch trash pump lineup.
- Restores Full Pump Output: — A cracked, worn, or damaged pump housing leads to pressure loss and reduced priming ability; replacing it with part 5000178012 restores the pump's rated discharge performance.
- Pressure-Integrity Design: — The housing must maintain a sealed fluid path under continuous pumping load; OEM material and wall-thickness specifications ensure it can withstand the operating pressures these pumps are built to handle.
The pump housing forms the main structural shell of the centrifugal pump, enclosing the impeller and directing water flow from the inlet port through the volute and out the discharge. It must maintain a leak-free seal under constant hydraulic pressure while withstanding the abrasion caused by debris-laden water passing through the pump. When a housing cracks, corrodes, or becomes physically damaged, the pump loses prime and discharge pressure, making it unable to move water effectively — often halting dewatering operations entirely.
