Working Principle

Pneumatic double diaphragm pumps field of the transferal of liquids and that is a market leader specialized in the production of industrial pumps for highly corrosive and aggressive environments. Diaphragm pumps are characterized by exceptional performance, power and strength, making them ideal for pumping liquids with high apparent viscosity even if containing suspended solids.

All products are scrupulously tested to meet the harshest working conditions of the chemical, textile, food, ecologic, graphic, tanning, ceramics, electronic, galvanic, oil production, petrochemical, paints, biodiesel industries and many others.


How it works

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.
