Diaphragm pumps are robust and safe to run dry. They are characterized by gentle pumping of low-viscosity to highly viscous and powdery products. The low-shear mode of operation is particularly ideal for media with fragile or abrasive solids content. Easy handling and high operational reliability save time and resources.
Compared to electric diaphragm pumps, air-operated diaphragm pumps offer additional advantages. They can also be used without a power supply and very easily in ATEX areas.
The function of the diaphragm pump is based on the oscillating movement of a flexible diaphragm, which is driven by an eccentric or compressed air. This movement generates suction and pressure cycles. Ball or flap valves control the product flow. During one cycle the diaphragm sucks in the medium, during the next it expels it. The continuous change generates a flow rate.
The double diaphragm design results in less pulsation. Pulsation dampers can be used to additionally counteract this and ensure a more even flow rate.
