Abstract
A control unit for a solenoid pump, the solenoid pump including: an inlet port, an outlet port, and a first through-bore connecting the inlet and outlet ports; a plunger disposed within the first through-bore and including a second through-bore; a spring arranged to urge the plunger toward the outlet port; a solenoid coil disposed about a portion of the plunger and arranged to displace the plunger toward the inlet port in response to direct current coil power applied to the solenoid coil, the control unit including a microcontroller operatively arranged to control the solenoid coil, a first transistor operatively arranged to receive an external signal and communicate the signal to the microcontroller to control the solenoid coil, and a second transistor, arranged between the microcontroller and the solenoid coil, the second transistor operatively arranged to energize and de-energize the solenoid coil in response to the microcontroller.
