The Wacker Neuson Housing is a genuine OEM component designed for the PDT2, PDT2A, PDT2B, PDI2, and PDI2A series 50mm (2-inch) diaphragm trash pumps. As a direct OEM part, the is manufactured to the same specifications as the original, ensuring a correct, hassle-free installation on your pump. This housing is a critical structural component shared across multiple PDT2 and PDI2 variants, making it a versatile stock item for dealers and operators running these machines in the field.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original dimensional and material specifications for the pump housing, ensuring correct wall thickness, port alignment, and sealing surfaces that aftermarket alternatives may not replicate.
- Drop-In Replacement: — Matches the original mounting bolt pattern and port configuration on PDT2 and PDI2 family pumps, allowing the housing to seat and seal properly without rework or machining.
- Broad PDT2 and PDI2 Fitment: — Confirmed fit across PDT2, PDT2A, PDT2B, PDI2, and PDI2A inline and standard diaphragm trash pump configurations, covering a wide range of 50mm pump serial ranges.
- Structural Integrity Under Pressure: — A sound pump housing maintains the sealed fluid path needed for consistent suction and discharge performance; a cracked or damaged housing leads to pressure loss, priming failure, and fluid ingress into internal components.
- Fluid Containment and Pump Longevity: — Proper housing integrity prevents abrasive slurry and debris from contacting internal diaphragm and valve components, directly extending the service life of the pump's wetted parts.
The housing is the primary structural enclosure of the pump's fluid chamber, forming the sealed cavity in which the diaphragm flexes to move water, slurry, and debris from the suction port to the discharge port. It also serves as the mounting interface for the diaphragm, valve assemblies, and pump body, meaning its dimensional accuracy is essential for maintaining proper compression and alignment of all internal components. When the housing is cracked, worn, or warped, the pump loses its ability to hold prime, discharge flow becomes erratic, and continued operation risks damage to the diaphragm and check valves.
