The Wacker Neuson Gear is a genuine OEM component designed for the PDT and PDI series diaphragm trash pumps, including 50mm/2-inch and 75mm/3-inch models. As a direct factory replacement, this gear is manufactured to the exact tolerances required to maintain correct drive engagement within the pump mechanism. It is confirmed for use across the PDT2, PDT2A, PDT2B, PDT3, PDT3A, PDI2, PDI2A, PDI3, PDI3A, and PD3B series pumps, making it a widely applicable service part for Wacker Neuson diaphragm pump fleets.
Key Features
- OEM-Spec Tooth Geometry — Manufactured to Wacker Neuson's exact tooth profile and pitch specifications, ensuring correct mesh engagement and smooth power transfer within the pump drive train.
- Direct Drop-In Replacement — Mounts to the original shaft position and interfaces with mating drive components without modification, restoring factory drive function immediately upon installation.
- Broad PDT and PDI Series Coverage — Confirmed fitment across 2-inch and 3-inch diaphragm trash pump models in the PDT2, PDT3, PDI2, PDI3, and PD3B families, covering a wide range of Wacker Neuson pump configurations.
- Restore Full Pump Output — A worn or damaged gear disrupts diaphragm actuation timing and reduces pumping efficiency; replacing it with a correctly sized OEM gear restores rated flow and discharge performance.
- Genuine Wacker Neuson Part — Sourced directly through authorized Wacker Neuson supply channels, carrying part number 5000051332 for straightforward verification against your machine's parts manual.
The gear in a diaphragm pump drive assembly transmits rotational motion from the engine or motor to the eccentric mechanism that actuates the diaphragm. As the gear turns, it drives the reciprocating action that creates the suction and discharge strokes responsible for moving fluid through the pump. When this gear wears, chips, or loses proper mesh with its mating component, the diaphragm stroke becomes inconsistent or stops entirely — resulting in reduced flow, loss of prime, or complete pump failure. Replacing a damaged gear promptly keeps the pump operating at its rated capacity and prevents downstream damage to other drive components.
