A pump includes a liquid housing having a liquid chamber with a piston/diaphragm assembly arranged therein that responds to a suction stroke and draws liquid into the liquid chamber, and responds to a pressure stroke and provides liquid from the liquid chamber; and a gas housing having a slide valve assembly separating first and second gas chambers. The slide valve assembly responds to a suction-to-pressure-force at the suction stroke conclusion, changes from a suction-to-pressure stroke state, provides gas from the first to second gas chamber through the slide valve assembly, and provides the pressure stroke so liquid passes from the liquid chamber; and responds to a pressure-to-suction-force at the pressure stroke conclusion, changes from the pressure-to-suction stroke state, provides gas from the second chamber through the slide valve assembly, and provides the suction stroke so liquid is drawn into the liquid chamber.

An electrochemical pump adopts a hybrid pulse to intermittently activate an electrochemical reaction. The abovementioned electrochemical pump can save power effectively to prolong the lifetime of the electrochemical pump. In addition, an electrochemical pump increases the bonding strength between electrodes and a substrate by covering edges of the electrodes with an insulating layer to avoid electrode delamination caused by high-power electrochemical reactions. A delivery device using the abovementioned electrochemical pump is also disclosed.
