Description
Drain excavation ditches, sump basins, and elevator shafts automatically. The Wacker Neuson PSA2 800 2in Automatic submersible pump clears standing water without manual switch monitoring. An integrated electronic sensor activates pump cycles upon liquid contact. The pump cannot pass solids exceeding 0.24-inch diameter without risking impeller jams.
Lightweight aluminum alloy forms the motor frame, encased in an impact-resistant synthetic rubber jacket. A semi-vortex urethane rubber impeller resists abrasive scoring from suspended concrete fines. Dual silicon carbide mechanical seals operate within an internal oil chamber for run-dry defense. The electronic level sensor mounts straight to the housing without mechanical float arms. Top-discharge geometry cools motor windings.
Automatic Dewatering System Specs
Restoration technicians clear groundwater from basements without constant supervision. The solid-state electronic sensor starts the motor when water touches the sensor probe.
- Continuous-duty 1.0-horsepower motor operates on standard single-phase 110-volt circuits
- Semi-vortex urethane impeller delivers 82 GPM maximum water discharge volume
- Solid-state electronic level sensor starts and stops pumping without mechanical floats
- Silicon carbide mechanical seals run inside an oil chamber for dry-run protection
- Top-discharge water cooling keeps motor windings safe during low water levels
- Heavy 32-foot rubber power cord includes strain relief to prevent electrical shorts
- Standard 2-inch discharge fitting attaches straight to flat contractor lay-flat hose
Electric Motor Load Telemetry
Bench testing demonstrates the motor draws 9.4 Amps across 115-volt power under a 25-foot dynamic discharge head. Pump output stabilizes at 64 GPM through 50 feet of 2-inch lay-flat hose. Motor stator temperature reaches 148°F during shallow low-water operation. Acoustic sensors record 58 dBA underwater and 66 dBA above the water line.
Jobsite Operation Mechanical Realities
You lower this pump into manholes using a dedicated steel lifting rope attached to the handle. The slender cylindrical frame fits down narrow 8-inch inspection casings. Do not lift or suspend this pump by the rubber electrical cable. Pulling the power cord pulls internal lead wires from terminals and causes shock hazards.
- Inspect the cast-iron strainer base for compacted silt before lowering into water
- Check oil bath clarity in the mechanical seal chamber once every 6 months
- Wash the exterior pump housing with clean water after pumping acidic runoff
Factory Warranty Coverage Roster
Wacker Neuson covers this submersible pump with a 2-Year limited commercial warranty. The shipping carton contains the submersible de-watering pump, 32-foot power cord, 2-inch hose discharge adapter, and technical service manual.
