Solenoid Diaphragm Liquid Pumps

Diaphragm liquid pumps with solenoid drive are a great choice for customers who want superior flow rate control with the added flexibility to deliver single strokes. Solenoid Diaphragm Liquid Pumps from KNF also have an integrated valve function, which prevents uncontrolled flow of liquid in off-mode (NC-valve). Most impressive is the lifetime of these pumps - the linear drive delivers high performance for up to 10,000 hours (that's more than 250 million strokes)!
