Description
Drain residual water from elevator shafts, basement sumps, and flooded building floors. The Tsurumi HSE2.4S Electric Submersible Pump unit clears standing water down to floor level. A 0.5-horsepower electric motor powers a semi-vortex urethane rubber impeller. The 0.28-inch solids clearance limits passage of gravel and thick building demolition rubble.
Corrosion-resistant aluminum alloy forms the motor frame, protected by a tough synthetic rubber outer casing. A semi-vortex urethane impeller resists severe abrasion from sand fines and concrete dust. Dual silicon carbide mechanical seals run inside an oil lifter chamber to survive dry running. Thermal motor cutoffs shut off power during high-temperature conditions. Top-discharge geometry cools the motor housing.
Low-Water Submersible System Specs
Restoration technicians clear shallow standing water without leaving deep puddles on concrete slabs. The internal oil lifter protects mechanical seals even if the pump runs dry.
- Continuous-duty 0.5-horsepower motor operates on standard single-phase 115-volt circuits
- Semi-vortex urethane impeller delivers 53 GPM maximum water discharge volume
- Automatic electronic water level sensor starts and stops the pump without float switches
- Internal oil lifter lubricates mechanical seals during shallow low-water conditions
- Silicon carbide mechanical faces resist abrasive wear from suspended silica sand
- Heavy 32-foot power cord features anti-wicking block to stop water shorts
- Standard 2-inch discharge port attaches straight to contractor lay-flat discharge lines
Bench Dyno Operational Telemetry
Dynamometer testing confirms the motor draws 5.4 Amps across 115-volt lines under a 15-foot dynamic discharge head. Pump output stabilizes at 38 GPM through 50 feet of 2-inch hose. Stator temperature reaches 142°F during extended low-water running. Acoustic telemetry records 56 dBA submerged and 63 dBA in open air.
Jobsite Operation Mechanical Realities
You lower this pump down narrow utility sumps using a rope hitched to the top steel handle. The compact cylindrical frame fits into tight 8-inch basins. Do not pick up or move this machine by the rubber power cable. Yanking the electrical cord pulls wires from internal terminals and causes electrical shocks.
- Inspect the rubber suction strainer for trapped leaves before lowering into water
- Check seal chamber lubricating oil clarity through the inspection port once a year
- Rinse the pump housing with fresh water after pumping abrasive concrete slurry
