Overview
A urethane impeller spinning inside a slim aluminum body pushes water out through the top of the Tsurumi dewatering pump, routing it past the motor to cool it. Dual silicon carbide seal faces are built for long service in harsh conditions.
Its slim build drops into narrow caissons, and the stated lift handles deep holes. Without a float or relay listed, it runs only while powered, which suits attended work.
Who it's for
Suits construction and general dewatering where a crew monitors the pump and needs lift for deep holes. Unattended pits are better served by a model with an automatic switch.
Pros and cons
- Fits narrow caissons
- Strong listed lift height
- Long power cord
- Urethane wear parts
- No automatic switch listed
- Flow figure differs from the title
- Spec sheet wrongly calls it a diaphragm pump
Performance notes
Delivered flow falls as lift rises, so the listed flow applies near the surface and shrinks toward the maximum lift. Top discharge routes water around the motor for cooling, which allows continuous duty at low water levels and short dry runs.
