Key Features
- Genuine OEM Construction: — Manufactured by Wacker Neuson to original design tolerances, ensuring the arm functions exactly as intended within the diaphragm pump mechanism.
- Direct Drop-In Replacement: — Engineered to match the original mounting points and geometry of the PDT2A, PDT2, and PDI2A(I) pump assemblies for a straightforward installation.
- Broad Diaphragm Pump Fitment: — Compatible across the PDT2A, PDT2, and PDI2A(I) model lines, covering a widely used range of Wacker Neuson diaphragm pump configurations.
- Restored Pump Action: — A correctly functioning arm maintains the precise mechanical motion that drives diaphragm displacement; a worn or damaged arm causes erratic pumping, reduced flow, or complete pump failure.
- OEM Part Number Assurance: — Ordering by Wacker Neuson part number 5000179879 ensures you receive the correct component for your pump model, eliminating guesswork during maintenance or repair.
The arm is a core mechanical linkage within a diaphragm pump, transferring motion from the drive mechanism to the diaphragm itself. This reciprocating action creates the pressure differential that draws fluid in and pushes it out through the pump. When the arm wears, bends, or fails, the diaphragm can no longer cycle correctly, resulting in loss of suction, reduced output, or complete pump stoppage — making timely replacement essential to keeping the pump operational.
