Solenoid pumps are one of the simplest types of pumps because they have very few moving parts. When current is applied to a solenoid pump, the electromagnetic core moves against a spring to slide a diaphragm into the discharge position. When current is removed, the diaphragm slides back into the suction position.Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers..
