NEMO® BT Immersible Pumps With Bracket or Flanges

The ideal solution for emptying containers, sewage tanks or pits in confined spaces

NEMO® BT immersible pumps with hanging bracket for crane suspension or dome cover flanges are used for the low-pulsation emptying or conveying out of open or closed barrels, tanks, clarifiers, pits and similar containers.

They are also ideally suited for the use under limited space conditions, where there is  danger of cavitation or a very low NPSH value. In addition, the pumps equipped with a bracket for crane suspension are used for emptying containers with water- and environmentally hazardous substances where the usual emptying through a flange at the bottom of the container is not permitted. Moreover, the NEMO® BT is insensitive to sand content in the medium being conveyed and impresses with its very high pumping speed as well as exact dosing accuracy.

1 Rotor
In wear- and corrosion-resistant designs, even as wear free ceramic rotor NEMO CERATEC®.

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
Standard with single-acting, bi-directional, wear-resistant mechanical seal. Upon request, with single- or double-acting mechanical seals in various designs and from various manufacturers, cartridge and special seals as well as packed glands.

5 Suction and discharge housing
Flange and threaded connections in accordance with DIN and international standards. Materials in cast iron, steel, chrome-nickel-steel rubberized; special materials upon request.

6 Block construction
The drive is flanged directly to the lantern of the pump, resulting in compact dimensions, low total weight, constant axial heights irrespective of the construction type and size of the drive, and ease of maintenance and serviceability as well as high efficiency.

NEMO® BT immersible pumps with dome cover flange are used for low-pulsation emptying of closed barrels and similar containers.
