• high efficiency

• high variety of shaft sealing systems

• easy serviceability

Advantages of the NEMO® SY Bearing Block 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 including the 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 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 Bearing Block with Free Shaft Extension
Large double bearing ensures a high level of shaft stability and thereby ideal conditions for a great variety of mechanical seals. The free shaft extension makes it possible to use any drive type including diesel and hydraulic drives.
