Advantages
of the NEMO® BY 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
-
easy serviceability

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 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.
