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 factory replacement, this part is manufactured to the same specifications as the original, ensuring a correct, trouble-free installation on your pump. Fitment covers a wide range of PT3-family configurations, including standard PT3 models, the PT3A 75mm/3-inch centrifugal variants, and PT3H pump assemblies. Sourcing a genuine Wacker Neuson part means you get the exact component engineered for your machine — no guesswork, no adaptation.
Key Features
- Genuine OEM Construction — Cast and finished to Wacker Neuson's original dimensional tolerances, maintaining the correct volute geometry and port alignment critical to pump efficiency.
- Direct Bolt-On Replacement — Matches original mounting patterns and port interfaces on PT3, PT3A, and PT3H pumps, allowing straightforward swap-out without machining or modification.
- Broad PT3-Family Coverage — Compatible across multiple PT3, PT3A, and PT3H configurations, including standard and 75mm/3-inch centrifugal trash pump variants.
- Maintains Pumping Performance — A correctly fitted housing seals the impeller chamber properly, preserving suction lift capacity and discharge pressure; a cracked or worn housing causes cavitation and loss of prime.
- Fluid-Contact Integrity — Designed to handle the abrasive slurries and debris-laden water that PT3-series trash pumps are built for, holding up under continuous field use.
The pump housing forms the main structural shell of the centrifugal pump's wet end, enclosing the impeller and creating the sealed volute chamber that converts impeller rotation into fluid pressure and flow. It also provides the inlet and outlet ports through which water and entrained solids pass during operation. When the housing is cracked, eroded, or damaged at its sealing faces, the pump loses the ability to maintain prime, resulting in reduced flow, loss of suction lift, and potential overloading of the engine or motor. Replacing a compromised housing with a genuine Wacker Neuson 5000178012 restores the pump's full self-priming capability and rated discharge performance.
