Tsurumi NK Submersible Pumps
Tsurumi NK Submersible Pumps are a highgrade pump that can be used efficiently in draining in civil engineering through to deepwell applications.
Maximum depth of submersion 25m.
Pumped water cools the motor and discharges as illustrated. The motor can be cooled even when pumping a small amount of water. The top discharge arrangement allows access into areas with space limitations.
Increased water-pressure resistance
An newly developed mechanical seal endures water pressure of up to 2,5 kgf/cm². This makes the pumps usable at greater depth, such as in deep wells, to say nothing of use at general construction sites.
