WOrKING prINCIpLe
pneumatic double membrane pumps for industrial pumping of
liquids and highly corrosive and aggressive acids.
Characterised by their high performance, high power and stur-
diness, which make them suitable for pumping liquids with high
viscosity, including in the presence of suspended solids. They
meet the working needs of the chemical, textile, food, ecologi-
cal, graphics, tanning, ceramics, electronics, galvanic, oil, paint,
biodiesel, urea pumping and other industries
The compressed air introduced by the pneumatic exchanger
behind one of the two diaphragms generates compression and
pushes the product into the delivery duct, at the same time, the
opposing diaphragm that is integral with the exchanger shaft
creates a vacuum and intakes the fluid.
Once the stroke has been completed, the pneumatic exchanger diverts the
compressed air behind the opposing diaphragm and the cycle is reversed.
