For mobile and stationary application

Lutz horizontal eccentric screw pumps are suitable for pumping aqueous to highly viscous Newtonian and non-Newtonian media. The pumps are suitable for abrasive, solids containing and shear sensitive media, as well as for neutral, aggressive and easy fl ammable liquids under high delivery pressure.


  • By positioning outside of the container it is possible to pump liquid out of the stacked containers - or containers which are not accessible from the top
  • Due to the compact construction height, emptying at limited room height is possible
  • Easy handling of heavy pumps
  • No physical strain due to lifting
  • Easy replacement of wearing parts by the new rotor/stator combination
  • Fluid transfer is possible in either direction of rotation
  • By replacing the rotor/stator unit, an easy change of size is possible
  • Also available in PURE design

Easy change of size

  • A change between different stator materials is possible with keeping the same stator sleeve.
  • A conversion from 25.1 to 75.1 is possible by replacing the stator sleeve.
  • Outer tube and shaft always have the same length and are compatible with each rotor/stator unit.
  • By replacing stator, rotor and stator sleeve, a conversion to any rotor/stator combination is possible.

Optional with stainless steel trolley with normal or conductive wheels. In conjunction with a flow meter and operating unit, a mobile filling station is created.
