Description
De-water flooded foundation footings, retention ponds, and utility manholes on schedule. The Wacker Neuson PS3 Single-Phase Submersible pump clears massive liquid volumes across harsh construction jobsites. A 1.0-horsepower electric motor turns a semi-vortex impeller. The pump cannot pass solid rocks larger than 0.25-inch diameter without risking impeller jams.
Ductile iron forms the pump casing and bottom strainer, resisting rough jobsite abrasion. The silicon carbide dual mechanical seals run in an oil bath to endure prolonged dry running conditions. Thermal motor protection shuts down electrical feed during high-temperature events. A top-discharge design cools the motor housing with pumped water. Solid stainless steel motor shafts resist shaft deflection.
Submersible De-Watering Specs Overview
Excavation crews clear stormwater from jobsite trenches without priming delays. Continuous top discharge design permits pumping down to shallow water levels without overheating.
- Electric 1.0-horsepower motor operates on standard single-phase 110-volt jobsite power
- Semi-vortex cast-iron impeller delivers 84 GPM maximum water discharge volume
- 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
- Rugged ductile iron strainer base blocks gravel larger than 0.25-inch diameter
- Tough 32-foot rubber power cord includes strain relief to prevent electrical shorts
- Standard 3-inch discharge fitting attaches straight to flat contractor lay-flat hose
Electric Motor Load Telemetry
Bench testing demonstrates the motor draws 9.6 Amps across 115-volt power under a 25-foot dynamic discharge head. Pump output stabilizes at 62 GPM through 50 feet of 3-inch lay-flat hose. Motor stator temperature reaches 152°F during shallow low-water operation. Acoustic sensors record 58 dBA underwater and 66 dBA above the water line.
Worksite Performance Practical Notes
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
Commercial Warranty Manifest Terms
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, 3-inch hose discharge adapter, and technical service manual.
