ABSTRACT OF THE DISCLOSURE A reciprocating, pneumatically operated pump apparatus is described for use in a post-mix syrup dispensing operation which comprises a fail-safe pump reversing system which includes a valve actuating member for reversing the valve mechanism which controls the reciprocating pump action. An overcenter, snap- acting mechanism is provided to preclude the valve actuating member from sticking in a central position. The snap-acting mechanism is configured to substantially preclude bearing load in a direction transversely of the direction of movement of the valve actuating member. The pump housing is molded plastic with all fluid passages and pump connections formed therein, to minimize the number of external connections. The output valves of the pump are positioned at the highest point in the discharge sections of the piston chamber to minimize the accumulation of air bubbles.
