α-Power Series Metering Pump

Flow rate adjustment methods

Manual adjustment:change the stroke length through handwheel

■Adjust flow rate is available either during running or at standstill

■Minimum adjustment scale is 1%

Electric actuated stroke controller: receive external control signal to adjust the stroke length

■Power source: 220V-50Hz-single phase

■Input signal: 4-20mA simulated signal

■Output signal: 4-20mA/1-5V simulated signal, used for record display and control system

Frequency conversion controller: receive external control signal to adjust the stroke speed

■Power supply: 220V-50Hz-single phase or 380V-50Hz-three phase

■Input signal: 4-20mA simulated signal

α-Power Series Data Sheet
