ABSTRACT:
A self-contained liquid manifold attachable to a drive mechanism for a reciprocable pump, the manifold having a pumping cylinder, pressure transducer, pressure control mechanism, drain valve and control mechanism attached thereto, and liquid delivery outlets all forming a part thereof. The manifold and its associated components are removable from the reciprocable drive mechanism by detaching two fasteners. The pressure transducer and control mechanism includes a piston and cylinder removably indexed in a manifold bore, and an electrical switch in an adjacent housing with a ball bearing on the piston and a push rod resting on the ball bearing, the other push rod end constrained by a ball and spring combination.
