The NEMO® SY
Progressing Cavity Pump is used for demanding applications
in every branch of industry around the globe. In bearing
block design with free shaft extension, this pump can be
run with any type of drive, such as servo motors, diesel
motors or hydraulic drives. The pump can also handle high-pressure
applications. Four rotor/stator geometries are available,
enabling the pump to be customized perfectly to your application
case. The NEMO® SY is suitable
for all branches of industry where low- to mid- viscosity
and/or shear-sensitive, abrasive or adhesive media must
be safely and gently conveyed.
