Diaphragm / Piston Pump

Piston pumps can operate without problems in environments with humid air currents and have no specific operating limitations.

DOVAC also offers versions with a protective housing and intake filter, which can be supplied as a mobile unit. The operating principle of piston pumps relies on a piston moving up and down in a cylinder. This piston is equipped with valves that suck in and blow out air. When used as compressors, they produce a pulsating airflow, so it may sometimes be necessary to connect them to a storage tank.
