German BONDIOLI & PAVESI pumps, BONDIOLI & PAVESI models, BONDIOLI & PAVESI prices

BONDIOLI & PAVESI pumps are rotary pumps that rely on the change and movement of the working volume formed between the pump cylinder and the meshing gears to transport liquid or increase its pressure. Two enclosed spaces are formed by two gears, the pump body, and the front and rear covers. When the gears rotate, the volume of the space on the disengaging side increases from small to large, creating a vacuum that draws in the liquid. The volume of the space on the meshing side decreases from large to small, squeezing the liquid into the pipeline. The suction chamber and the discharge chamber are separated by the meshing line of the two gears. The pressure at the outlet of the gear pump depends entirely on the resistance at the pump outlet.
