Claw pumps D.V.P. Vacuum Technology

The new PA.155 Claw pumps create air volume and transfer it through the intake duct to the outlet duct by means of the rotation of two claw shaped rotors in a moulded chamber.

The dry running contactless rotation of the rotors is synchronized by gerars without any lubricant present, thus avoiding any residue generated by friction or rubbing during rotation.

The gear wheels are lubricated with oil and are enclosed in two compartments separated from the rotation chamber by gaskets.

Claw pumps guarantee low operating costs thanks to moderate energy consumption and high efficiency. Maintenance is minimized and the level of performance is durable thanks to the lack of friction between the moving rotors. The standard equipment of our new PA.155 Claw pumps includes shock mounts and vacuum control valve.
