NEMO® Immersible Pumps BT

General

NEMO® Immersible Pumps are used to empty barrels, containers, tanks, sedimentation tanks, pits etc. and where space is restricted, there is a risk of cavitation or there is very low NPSH. The pumps are also used to empty containers holding materials that are hazardous to water or the environment for which standard emptying via a flange on the bottom of the container is not permitted.

Technique

Dependable conveyance with no overflow

1 Rotor
In wear- and corrosion-resistant designs.

2 Stator
Vulcanized into the tube with sealing on both sides in a variety of elastomers, plastics and metals. Stator inlet with hopper-shaped opening for improved feed of the product into the conveying chamber. The stator is oil-, acid- and alkali-resistant.

3 Drive Chain
Coupling rod and two gimbal joints for the transmission of power from the drive to the rotor.

4 Shaft Seals
