For particular uses, such as harmful substances needing a leakage free solution, SABI proposes a single or double diaphragm type hydraulic end.

The capacity range varies from few ml/h up to 4,500 lt/h with a pressure of 250 bar.

The diaphragms are hydraulically driven.

The diaphragm hydraulic solution can be provided with following accessories:

  • pressure gauge or pressure switch for the rupture detection of one of the two diaphragms, to prevent that the pumped fluid comes into contact with the ambient;
  • valve of automatic recovery of the hydraulic circuit fluid, lost through the safety valve;
  • incorporated over-pressure valve.
