Description
Pump heavy drilling mud, thick sludge, and raw muck out of utility trenches. The Wacker Neuson PDT2A 2 Inch gasoline diaphragm pump handles thick slurry without binding. A 118cc Honda GX120 gas engine drives a reinforced synthetic diaphragm. Diaphragm pump mechanics produce pulsing fluid flow that shakes unanchored discharge hoses.
Rugged die-cast aluminum forms the pump volute and casing to reduce worksite transit weight. A commercial 118cc Honda GX120 engine links to an oil-bathed spur gear transmission. The heavy-duty thermoplastic diaphragm sweeps inside the chamber to draw viscous sludge. Neoprene flapper check valves pass semi-solids up to 1.5-inch diameter without jamming. Tubular steel frames protect components.
Diaphragm Slurry System Specs
Excavation crews clear thick mud slurries that bind conventional centrifugal trash pumps. Positive displacement diaphragm action moves slow-flowing mud without loss of priming vacuum.
- Commercial 118cc Honda engine provides dependable shaft torque across continuous shifts
- Positive displacement diaphragm moves 50 GPM of viscous mud and heavy sludge
- Neoprene flapper valves pass suspended semi-solids up to 1.5-inch diameter without clogging
- Die-cast aluminum casing cuts unit weight for fast jobsite transport and loading
- Oil-lubricated spur gear reduction converts high engine RPM to slow diaphragm cycles
- Standard 2-inch NPT suction and discharge ports connect straight to contractor hoses
- Pneumatic transport wheels permit fast movement across muddy construction terrain
Engine Dyno Slurry Telemetry
Dynamometer bench testing demonstrates the Honda engine holds 3400 RPM under continuous 15-foot suction lift conditions. Fluid discharge stabilizes at 48 GPM through 25 feet of 2-inch suction hose. Gearbox oil temperature stabilizes at 144°F after 3 hours of continuous sludge pumping. Fuel consumption registers 0.32 GPH. Acoustic output measures 84 dBA at 5 meters.
Operational Boundaries Field Realities
You roll this balanced cart across construction sites using the folding steel handle. The large pneumatic wheels navigate rough trench spoil piles without sinking. Do not start this pump with closed discharge valves. Positive displacement pressure dead-heading tears the synthetic rubber diaphragm within three strokes.
- Inspect flapper valves for trapped rocks if suction vacuum levels begin dropping
- Check the gear drive oil level through the inspection plug once a month
- Flush internal pump chambers with clean water after pumping thick concrete slurry
Commercial Warranty Terms Manifest
Wacker Neuson covers this diaphragm pump with a 2-Year limited commercial warranty. The carton contains the diaphragm trash pump, steel cart with wheels, 2-inch hose couplings, and comprehensive operational guide.
