A multi-plunger reciprocating pump comprising a generally horizontally extending crankshaft and a plurality of generally horizontally extending cylinders alternately disposed at least generally above and below the centerline of the crankshaft. An oil pan is detachably mounted in the crankshaft housing below the crankshaft, whereby the oil pan is readily removable to facilitate axial removal of the crankshaft; and the crossheads connecting the crankshaft driven connecting rods to the piston rods are slidably mounted by bearing shoes adapted to be rotated 90 DEG for facilitating access thereto. Also, the suction and discharge valves for the cylinders are readily accessible without disconnection of any of the piping or manifolds of the pump.
