Piston pumps D.V.P. Vacuum Technology
Piston pumps may be used in presence of moisture and have no particular restrictions on use. Versions (series ZA box) are also available with safety guard and intake filter for use as mobile units.
The operating principle of piston pumps and compressors is based on a piston that alternatively moves in a cylinder. The cylinder is equipped with valves that inhale air (when the piston goes down) and exhale it outside (when the piston rises). When its head is integral with the piston rod the piston is defined oscillating. Unlike membrane pumps, piston pumps chamber is not completely sealed and does not guarantee a perfect airtightness circuit.
The main application fields include: electromedical, suction cups conveyors, laboratory applications and construction.
