The Wacker Neuson Housing is a genuine OEM component designed for PT4A and PT4A(I) series self-priming centrifugal trash pumps. Sourced directly from Wacker Neuson, this housing is manufactured to the exact specifications of the original part, ensuring a correct, trouble-free installation without guesswork. It is confirmed to fit the PT4A and PT4A(I) models, making it a straightforward replacement when the original housing is damaged, cracked, or worn beyond service limits.
Key Features
- Genuine OEM Construction — Cast and machined to the same dimensional tolerances as the original, ensuring proper fluid containment and structural integrity under pump operating pressures.
- Direct Drop-In Replacement — Matches all mounting points, port locations, and mating surfaces of the factory housing for a clean, bolt-on installation.
- Confirmed PT4A and PT4A(I) Fitment — Verified compatible with PT4A and PT4A(I) trash pump configurations, covering multiple serial range variants within each series.
- Protects Internal Pump Components — The housing encases the impeller and volute, maintaining the pressure differential that drives flow; a cracked or compromised housing leads to immediate loss of prime and pump output.
- Wacker Neuson Authorized Part — Carries full OEM part number 5100044572 for straightforward cross-reference and parts documentation.
The pump housing is the structural shell that surrounds the impeller and forms the volute passage responsible for converting rotational energy into fluid flow and pressure. It also seals the wet end of the pump, maintaining the prime that allows the unit to draw and move high-volume liquid with entrained solids. When a housing cracks, chips, or develops a leak at its mating surfaces, the pump loses its ability to hold prime, output pressure drops sharply, and continued operation risks damage to the shaft seal and impeller. Replacing a failed housing with the correct OEM part restores the pump to full working capacity quickly.
