General

Rotary Lobe Pumps are self-priming, valveless, positive displacement pumps

Design features

  • Self-priming, valve-less, positive displacement pump
  • Designed with two shafts with parallel axes
  • The shafts move relatively to one another thanks to external timing gear
  • The displacers (=rotors) roll off each other with minimum axial and radial clearance
  • In every position, the rotors and casing close the suction chamber against the pressure chamber
  • Gentle, low-pulsation pumping
  • For viscous, abrasive or shear-sensitive media or media containing solids
  • All metallurgies available
  • Design to NORSOK and customer specifications available
