The Wacker Neuson Housing is a genuine OEM component designed for the PT3, PT3A, and PT3H series self-priming centrifugal trash pumps. As a direct Wacker Neuson OEM part, it is manufactured to the exact specifications of the original, ensuring a proper fit and correct hydraulic performance within the pump assembly. This Housing is confirmed compatible across multiple PT3-family configurations, including the PT3, PT3A, and PT3H models. Keep part number on hand for scheduled maintenance or unplanned pump repairs to get your equipment back in service quickly.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original hydraulic tolerances, ensuring the internal flow path and volute geometry match the design intent of your PT3-series pump.
- Direct Drop-In Replacement — Matches the original bolt pattern and port dimensions for straightforward installation without rework or adaptation.
- Broad PT3-Family Compatibility — Fits PT3, PT3A, and PT3H pump models across multiple build configurations, covering a wide range of 3-inch discharge trash pump variants.
- Protects Pump Efficiency — A cracked or worn housing causes pressure loss and reduced flow output; replacing it with the correct OEM part restores full priming and discharge performance.
- Verified Wacker Neuson Part Number — Sourced directly from Wacker Neuson's parts catalog under part number 5000178012, so you can order with confidence that you're receiving the correct component.
The pump housing forms the main structural and hydraulic body of a centrifugal trash pump, enclosing the impeller and directing fluid flow from the inlet through the volute to the discharge port. It is responsible for maintaining the internal pressure needed to prime the pump and sustain consistent flow rates when handling water, slurry, or debris-laden fluids on the jobsite. When the housing is cracked, corroded, or damaged, the pump loses its ability to build suction, resulting in poor priming, reduced output, or complete pump failure — making timely replacement critical to keeping the unit operational.
