The Wacker Neuson Weight is a genuine OEM component designed for the PDT3A, PDI3A, PDT3, PD3B, and PDI3 series 75mm/3in diaphragm trash pumps. Sourced directly from Wacker Neuson, this part meets the exact specifications required to keep your pump operating as intended. It is a direct-fit replacement for all listed pump models, including both standard and inline diaphragm configurations across the 3-inch pump family.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original design tolerances, ensuring the weight delivers the correct mass and balance characteristics specific to diaphragm pump operation.
- Direct-Fit Replacement: — Engineered to install in the same position as the original, with no rework or adaptation needed during reassembly of the pump diaphragm assembly.
- Broad Model Compatibility: — Fits the PDT3A, PDI3A, PDT3, PD3B, and PDI3 series 75mm/3in diaphragm trash pumps, covering both standard and inline pump configurations.
- Diaphragm Stroke Integrity: — A correctly weighted component maintains consistent diaphragm cycling, supporting steady flow rates and preventing irregular pump action that can lead to premature diaphragm wear.
- Verified Part Number: — Part number 5000051300 is confirmed against Wacker Neuson's parts documentation for the listed 3-inch diaphragm pump series, supporting confident ordering.
The weight in a diaphragm pump plays a key role in regulating the reciprocating motion of the diaphragm assembly. By providing the correct inertial mass within the drive mechanism, it helps maintain a consistent stroke cycle, which directly affects the pump's ability to move fluid smoothly and at the correct rate. When this component is worn, damaged, or missing, the diaphragm stroke can become uneven or erratic, reducing pumping efficiency and accelerating wear on surrounding components such as the diaphragm itself and the valve flaps. Replacing a failed weight with the correct OEM part restores proper pump rhythm and protects the broader assembly from secondary damage.
