API 676 Rotary Lobe

  • API 676 Rotary Lobe SKU023

    Rotary Lobe Pumps are self-priming, valveless, positive displacement pumps. The even rotation of the rotor pair creates a vacuum on the priming side of the pump, which can be defined by the direction of rotation of the drive. This vacuum draws the liquid into the pump chamber. With further rotation, the pumped medium is conveyed past the pump wall into the pressure area. Up to six chamber charges are displaced with each drive rotation – depending on the rotor type. When the rotor is at a standstill, the pump seals off almost completely.
