  • Operating principle - Rotary lobe pumps | Boerger

    2021-3-1 · Rotary lobe pumps deliver a defined volume of fluid for each cycle of operation (i.e., each turn of the lobes). The only factor, aside from slip (mentioned later), that determines the amount of fluid being pumped is the speed at which the lobes turn (i.e., the pump’s operating speed, not the motor’s RPMs).
