Abstract
A reciprocating pump includes a fluid section that includes fluid-displacing members and a power section that includes crossheads coupled to a respective fluid-displacing member. The power section actuates the fluid section by actuating the crossheads through respective crosshead bores formed through the power section. The power section also includes structural members, pairs of support plates, and pairs of arcuate crosshead sections secured in place between the structural members against a respective pair of support plates. Each pair of the arcuate guide sections comprises a top section and a bottom section that form a portion of a respective crosshead bore. Each pair of the arcuate crosshead guide sections are also secured in place using clamping segments secured to edges of windows of the structural members by bolts extending through interior passages of the clamping segments and having threads that mate with threaded holes extending into the edges of the windows.
