NEMO® BT Immersible Pumps are used for emptying barrels, tanks, and pits. They are also used where space is limited and the danger of cavitation may be present. In addition, these pumps are suitable for emptying barrels containing materials hazardous to water and the environment.

Features of the NEMO® BT Immersible Pump:

  • compact design

  • high pressure stability

  • low-pulsation conveyance

  • high suction capability

NEMO® BT Immersible Pump offers you:

  • immersion depths of up to 15,000 mm

  • low life cycle costs

  • high efficiency

  • high variety of shaft sealing systems

  • easy serviceability

Advantages of the NEMO® BT Immersible Pump

  • can be operated under high conveying pressures and at high capacities

  • capable of pumping a great variety of substances

  • capacities can be adjusted proportionally

  • four different geometries for adjusting to the given application

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 funnel-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 of varied 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; also 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.
