2.1 Description
The NEMO
®
pump is a progressing cavity
pump.
The main components which determine the
system discovered by Professor René Moineau
are a rotating part, called the rotor (R) and a
static part, called the stator (S).
The rotor is a helical screw with an extremely
large pitch, large thread depth and small centre
diameter with round cross-section for ½-
geometry and elliptical cross-section for
⅔-geometry. The stator has a two start or resp.
3 start thread and is double or resp. 1.5 the
pitch length of the rotor. This provides space
for the medium between the rotor and stator.
When the rotor turns round inside the stator
the medium moves continuously from the inlet
to the outlet.
The universal NEMO
®
pump system unifies
many positive characteristics of other pump
types:
L Like centrifugal pumps NEMO
®
pumps have
no suction or pressure valves, but do have a
stable flow rate in proportion to the number
of revolutions.
L Like piston pumps NEMO
®
pumps have a
suction capability of up to 8.5 m vacuum
metric.
L Like membrane and peristaltic pumps the
NEMO
®
pump can transport every type of
inhomogenous, gaseous and abrasive
media, as well as those that are not of a
liquid consistency or contain solids and/or
fibrous material.
L Like gear pumps and screw pumps the
NEMO
®
pump is capable of coping with high
medium viscosities.
L Like piston, membrane, gear or screw
pumps the NEMO
®
pump can perform
dosing operations.
