ABSTRACT:
A reciprocating plunger pump is provided with a power section frame having open sides and vertical load-bearing walls spaced apart along the length of the frame. Separate, individually removable cradles are mounted on both sides of the frame directly to and extending between pairs of vertical walls. The cradles provide guides for linear reciprocating motion of main crossheads, which are attached to connecting rods driven by a rotating crankshaft. The cradles and the vertical walls are load-bearing so that the crankshaft may be rotated in either direction. The individually removable cradles provide easy access to both sides of the power section of the pump for inspection and maintenance of the power section components.
