Vacuum Pumps

The PVT400 is a dry aspirator which does not require auxiliary cooling since it has an air-injection system that permits continuous operation even with completely closed suction at a wide range of speeds. The lobe’s special profile and the sophisticated precision of the connection between the paddles permit high volumetric performance which is translated into smaller size for the same capacity and suction vacuum of up to 90%. The perfectly symmetrical and dynamically balanced lobes considerably reduce the vibrations transmitted to the supporting structure. The injection of external cold air contributes, together with the transfer of the gas by means of 6 distinct chambers, to reducing the pressure pulsations and therefore operation noise. The PVT400 satisfies all customer demands in terms of installation possibilities.
