Polytrace offers a range of AODD pump controllers for both speed and batch control. Two speed controllers, one with 4 adjustable preset speeds and the other set via a 4 to 20 ma dc signal means a complete control offering.
The control function is applied via the solenoid valve in the air supply of the pump.When the valve is energized one side of the pump receives air hence when it is unenergized , the other side of the pumps receives air. A cycle is then defined as the emptying from both chambers of th3 pump once.
