NEMO® Rotor/Stator Geometries

NEMO® Pumps belong to the group of positive displacement pumps. This pump group is based on the geometric fit between the rotating element (rotor) and the stationary element (stator) of the pump.

Pumping action is achieved by the rotor turning eccentrically within the stator.

All four pump geometries have the same outer dimensions. This modular design allows for all other components to be identical. When a change in flow rate or pressure is required, NEMO® Pumps can be adapted by simply changing the rotor and stator

  


S-Geometry (standard):

  • Multiple stages
  • Pressures up to 1000 PSI
  • Used where lower internal velocities are required
  • Flow Rate: 100%


L-Geometry:

  • Twice the volume per cavity
  • Greater volumetric efficiency
  • Lower circumferential velocity
  • Flow Rate: 200%

For S and L Geometries, NEMO® offers a solid ceramic rotor, the NEMO CERATEC®, with a 2 year guarantee.


D-Geometry:

  • Multiple stages
  • 2/3 the volume per cavity
  • High dosing accuracy
  • Compact dimensions
  • Pulsation-free conveyance
  • Flow Rate: 150%


P-Geometry:

  • Greater volumetric efficiency
  • 2/3 the volume per cavity
  • High dosing accuracy
  • Compact dimensions
  • Pulsation-free conveyance
  • Long service life
  • Flow Rate: 300%
