<p>A mud pump is provided that includes a frame and a motor mounted on the frame to rotate an eccentric shaft having substantially circular eccentric lobes. Each lobe is rotatably mounted in a slide. Each slide is slidably mounted in a slide frame. A piston rod is operatively coupled between one or both sides of each slide frame and a pump module. As the eccentric shaft turns, each lobe causes the slide to move up and down within the slide frame and the slide frame to move side to side. As the slide frame moves side to side, each piston rod operates a pump module. The outputs of each pump module can be coupled to a common manifold.</p> |
