The Wacker Neuson Weight is a genuine OEM component designed for the PDT2 and PDI2 series 50mm/2in diaphragm trash pumps. Sourced directly from Wacker Neuson, this part carries the same specifications as the original, ensuring it integrates correctly with your pump's internal assembly. Confirmed fitment spans the PDT2A, PDT2B, PDI2A, PDT2, and PDI2 model families. Keep a verified OEM replacement on hand so your pump returns to full operation without guesswork.
Key Features
- Genuine OEM Construction: — Manufactured to the exact mass and dimensional tolerances specified by Wacker Neuson, ensuring the weight performs its role in the diaphragm pump mechanism without variation.
- Direct Internal Fit: — Engineered to seat and secure exactly as the original within the pump assembly, allowing straightforward installation against existing mounting points.
- Broad PDT2/PDI2 Series Coverage: — Compatible with PDT2A, PDT2B, PDI2A, PDT2, and PDI2 models across multiple machine numbers in the 50mm/2in diaphragm trash pump family.
- Maintains Consistent Pump Stroke Dynamics: — The correct weight ensures the diaphragm cycles at the intended rate and force; an incorrect or worn weight can cause irregular flow, reduced output, or accelerated diaphragm wear.
- Verified Part Number Traceability: — OEM part number 5000074409 matches Wacker Neuson's own parts documentation, so you can confirm the correct component before placing your order.
The weight in a diaphragm pump works in conjunction with the reciprocating mechanism to control the stroke of the diaphragm — the flexible membrane that creates the suction and discharge action moving fluid through the pump. By providing the correct inertial mass at the right point in the drivetrain, the weight helps regulate stroke timing and force, directly influencing flow rate and pumping efficiency. When the weight is missing, damaged, or substituted with an incorrect part, the diaphragm can cycle unevenly, leading to reduced discharge performance, premature diaphragm fatigue, or pump failure under load.
