The Börger Rotary Lobe Pump

operating principle

• Self-priming, valveless, 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, solid, abrasive or shear-sensitive media
