A Solenoid-Driven Metering Pump is suitable when a wider control band of discharge volume is required or when complex control using external signals is required. The Solenoid-Driven Metering Pump has a maximum of 300 strokes/min (TACMINA benchmark), which means that it is 2 to 4 times faster than Motor-Driven Metering Pumps, and is capable of operation at a rate of once per minute (a control band of 300:1). It has an embedded controller and can be programmed to operate in a variety of ways..
