Abstract
The present invention involves improvements in reciprocable pumps. In one aspect, applicable to single action pumps, a quick release mounting means is provided for attaching a fluid end piece to a power frame. The frame has a tapered opening for receiving a barrel portion of the fluid end therein. A wedge device of mateable taper with the opening connects the barrel securely to the frame. The wedge extends around the transverse outer periphery of the barrel portion. Another aspect of the invention involves providing axially rotatable intake or exhaust manifolds. In a multiplex pump, the manifold may be rotatable as a unit, or the section for each conduit may be separately rotatable. This feature permits easier handling when making repairs, especially on larger pumps. Finally, in pumps having non-vertical suction or discharge passages, the valve counterbores are tilted toward a vertical direction, but not more than an angle at which straight-line machining of the suction or discharge passage is still possible. The more nearly vertical alignment of the valves reduces wear during service. This feature is especially applicable to fluid ends having suction and discharge passages which a…
