Overview
A construction excavation, trench or caisson gets a slim submersible dewatering pump that drops into narrow openings. Water exits through the top of the pump, a layout that helps cool the motor as it runs.
Tsurumi builds it for jobsite abuse, with urethane wear parts, dual silicon carbide seals and extended dry-run capability. No automatic float switch is listed, so it is controlled by hand rather than cycling on water level.
Who it's for
Contractors, rental yards and crews dewatering excavations and caissons get a slim, high-flow pump. Homeowners wanting an automatic basement sump pump should look for a model with a listed float switch.
Pros and cons
- Slim body fits narrow caissons
- Strong flow and lift
- Urethane impeller and wear plates
- Dual silicon carbide seals
- No float switch listed
- Discharge hose not included
Performance notes
Flow and lift come from the motor driving a urethane impeller, with output falling as lift height rises toward the listed maximum. Top discharge routes water past the motor for cooling, which allows continuous duty at low water levels. Dual silicon carbide seal faces are there for durability and longevity.
