Tsurumi NKZ Submersible Pumps provide very smooth passage of sandy earth and slime. A forcibly cooled motor ensures long and continuous pump operations exposed to air
Forced agitation
The agitator installed on the motor shaft extension forcibly agitates the fluid for easy and efficient transmission of sludge and slurry.
All pumps in this series provide very smooth passage of sandy earth and slime. A forcibly cooled motor ensures long and continuous pump operations exposed to the air. 4-pole motor used to achieve excellent durabiltiy and versatility. By offering a cast iron pump body durability is increased over standard aluminium body pumps. Spiral structure, marvelously facilitates the passage of sand, soil, sludge, or slime, without clogging.
