The operating cycles of the diaphragm pump can be controlled with a electric solenoid control valve. When the valve spool is tightened, one diaphragm is pressurized with compressed air, the other when the voltage drops. By alternating applying or dropping the control voltage, the pump is kept in motion. Via the frequency and the number of electromagnetic impulses, the flow rate or the batch can be optionally set. If necessary, the pump stops "precisely".
Pump control via electric impulses
For remote control of the pump via SPS, relay and switch
Ideal for batching and simple metering applications
