Very powerful 4 pole sand slurry pump Tsrurumi NKZ.
This series is especially suitable for pumping sandy sludge. The pump is Jacket cooled and can therefore operate at low water levels. 4-pole motor for exceptional durability and multiple applications. Solid cast iron pump and motor housing - far superior to aluminum designs. Spiral pump housing - excellent for pumping slurry or sand clog-free.
Powerful vortexing
Shaft-mounted agitator swirls the fluid and ensures that silt, sand and slurry are pumped with ease.
Jacket cooling
Flow of medium between motor housing and jacket, optimum cooling even in dry running and semi-submerged operation.
