Description
Drain abrasive sand slurry, bentonite drilling mud, and ground sediment from worksite trenches. The Tsurumi HSD2.55S Electric Submersible Pump unit provides extreme abrasion resistance in sandy wastewater. A 0.75-horsepower electric motor powers a high-chromium iron impeller. The 0.35-inch solids capacity prevents moving large river stone or heavy demolition debris.
High-chromium cast-iron forms the internal pump impeller and agitator, resisting erosion from silica sand. The ductile iron pump casing survives rough drops into concrete manholes. Silicon carbide mechanical seals run within an oil chamber featuring a patented oil lifter mechanism. Thermal motor cutoffs protect field windings against excessive electrical currents. Top-discharge geometry cools the motor housing.
Abrasive Slurry System Details
Drilling operators and utility crews clear abrasive silt without eroding internal pump components. High-chrome iron components outlast standard ductile iron during continuous sand pumping.
- Industrial 0.75-horsepower motor operates on standard single-phase 115-volt jobsite power
- High-chromium iron impeller resists severe erosion from abrasive silica sand slurry
- Integrated shaft agitator churns settled mud to keep suction strainers clear
- Patented oil lifter mechanism ensures seal lubrication during dry-run operation
- Anti-wicking cable entry blocks water intrusion through damaged power cord jackets
- Thermal overload protector prevents motor burnout during high mechanical loads
- Standard 2-inch discharge port attaches straight to contractor water discharge lines
Bench Dyno Operational Telemetry
Bench testing indicates the motor draws 7.2 Amps on 115-volt power under a 20-foot dynamic head. Water discharge measures 48 GPM through 50 feet of 2-inch lay-flat hose. Stator windings stabilize at 144°F during prolonged shallow pumping. Acoustic sensors record 57 dBA submerged and 64 dBA in open air.
Field Application Operator Boundaries
You swing this pump into deep sumps using a rope hitched to the top steel handle. The narrow diameter allows access inside tight pipe sleeves. Do not operate this unit without the intake strainer screen installed. Ingesting large rocks jams the high-chrome impeller and trips upstream circuit breakers.
- Inspect the shaft agitator for bound string or wire before starting operations
- Check mechanical seal oil levels once every 12 months of service
- Flush the pump volute with fresh water after pumping thick bentonite mud
