The Wacker Neuson Housing is a genuine OEM component designed for the PDT3, PDT3A, PDI3, PDI3A, and PD3B series 75mm/3in diaphragm trash pumps. Sourced directly from Wacker Neuson, this housing is manufactured to the same standards as the original part it replaces, ensuring a correct, consistent fit within the pump assembly. Compatible across a broad range of 3-inch diaphragm pump configurations — including both standard and inline models — this is a straightforward service replacement that keeps your pump operating as designed. Always verify your machine's model number and serial number before ordering to confirm compatibility.
Key Features
- Genuine OEM Structural Integrity — Manufactured by Wacker Neuson to match the original housing dimensions, port alignment, and material grade, ensuring the pump body maintains its designed flow characteristics.
- Direct Drop-In Replacement — Engineered to align with existing mounting points, diaphragm interfaces, and valve seat positions on compatible 3-inch diaphragm pump models — no redrilling or modification to surrounding components.
- Broad PDT3 / PDI3 Family Coverage — Fits multiple PDT3, PDT3A, PDI3, PDI3A, and PD3B pump variants, making part 5000051304 a practical stock item for fleets running these 75mm diaphragm pumps.
- Restored Pump Performance — A cracked, worn, or damaged housing compromises pressure containment and fluid routing; replacing it with a correctly spec'd OEM unit restores full pumping capacity and suction efficiency.
- Fluid-Path Integrity — As the primary structural enclosure for the pump's internal wetted components, a sound housing is essential to maintaining leak-free operation when handling trash-laden or abrasive fluids.
The housing is the main structural body of the diaphragm pump, enclosing and supporting the internal components — including the diaphragm, check valves, and fluid ports — that work together to move liquid through the pump. It forms the sealed fluid path between the inlet and outlet, so any cracking, warping, or erosion of the housing directly affects the pump's ability to maintain pressure and prime. When the housing is compromised, the pump may lose suction, leak fluid, or fail to deliver consistent flow — making timely replacement critical to keeping the unit productive on site.
