A solenoid pump forfluid control
The SSDP (photo) is a miniature fixed-displacement solenoid pump said to be highly accurate and reliable with few moving parts, making it an ideal replacement for inferior and more-costly diaphragm and peristaltic pumps. The SSDP works like an automatic syringe. An internal diaphragm uses minimal power to draw media into the device when energized and expels and seals off flow when deactivated, eliminating the need for an external shut-off valve. This process is repeated to deliver the necessary amount of media based on the application requirement. The pump is capable of self-priming when located up to 3 m above its fluid reservoir. Manual priming is also possible. — Spartan Scientific, a div. of Canfield Industries, Youngstown, Ohio
