Air Operated Double Diaphragm pumps are positive displacement pumps that displace a set volume of fluid with each stroke, making them very efficient for accurate chemical dosing.
The air operated diaphragm pump is the most used type of diaphragm pump, having applications in many different industries. They operate by flexing diaphrams to increase and decrease volume in the chambers, alternately drawing fluid into the chamber, and expelling it into the outlet pipe.
These pumps are intrisicly safe, making them perfect for situations in which pumps are required to operate without an operators continued attention. Thair pneumatic control means that they are also ideal for operating in zone one areas. The pump is simply turned on or off by either closing the fluid discharge valve anywhere on the discharge line or by regulating the air supply.
