  Working principle

(1)By the eccentric wheel (no. 1) rotates, three plungers (no.2) are alternately pushed.

(2) The plungers push three diaphragm by turns (no. 3).

(3)The diaphragms exert pressure to the liquid.

(4) The valve plates and valve seats (no. 4 and no. 5) of the pump make same function as one-way valve, making open-close working condition, and make liquid finish enter, pressand discharge from pump.
