An electromagnet-based pump generates reciprocating motion by attracting the solenoid plunger when energized, which moves the diaphragm to deliver a pre-determined amount of fluid.

This type of pump is suitable when a wider range of control for discharge volume is required, or when complex control using external signals is necessary.

A Solenoid-Driven Metering Pump is a type of pump that utilizes an electromagnet as the driving power. When the pump is energized, the electromagnet attracts the solenoid plunger, which generates a reciprocating motion that moves the diaphragm to deliver a pre-determined amount of fluid. This type of pump is ideal for situations where a wider control band of discharge volume is required or when complex control using external signals is necessary.

Compared to Motor-Driven Metering Pumps, the Solenoid-Driven Metering Pump is faster, with a maximum of 300 strokes per minute, as compared to the TACMINA benchmark. It is capable of operation at a rate of once per minute, offering a control band of 300:1. The pump comes with an embedded controller that can be programmed to operate in a variety of ways. This makes it highly versatile and adaptable to different pumping needs. Furthermore, the Solenoid-Driven Metering Pump can be used with AC100 to 240 V (±10%) power supplies, allowing it to be safely stocked for use across various sites and applications without worrying about voltage fluctuations.
