Air operated diaphragm pumps are very common in many industry sectors. They are used for pumping a wide variety of fluids, including high viscosity ones. The diaphragm pumps are ideal for pumping chemicals, petrochemicals, waste water, solvents or substances containing solids reaching a few millimetres.
They are suitable for applications where the pump must be partly or fully submerged in the fluid that is being pumped (then, the air outlet must be extended above the fluid level) or for use in potentially explosive environments (ATEX). The diaphragm pump can run dry without any damage e.g. when one of the lines is blocked.
The fluid outlet pressure of the pump is the same as the air inlet pressure.
The body is made of polypropylene, aluminium or stainless steel. The membrane is available in: EPDM, NBR, PTFE + HYTREL®, HYTREL®, SANTOPRENE ™.
!Remember, that all diaphragm pumps presented can only be used for fluids with a flash point above +55° C.
