Abstract
A mud pump is provided that includes a pump shaft having substantially circular eccentric lobes. Each lobe is rotatably mounted in a connecting rod that, in turn, moves a slide in a horizontal and linearly manner. A pony rod operatively couples a pump fluid end module to one or both sides of each slide frame and a pump fluid end module. As the pump shaft turns, each lobe causes the slide to move side to side. As the slide moves side to side, each pony rod operates a pump fluid end module whose outputs can be coupled to a common manifold.

A mud pump, comprising:
- a) a frame;
- b) at least one pump fluid end module disposed on the frame, the at least one pump fluid end module comprising an inlet port and an outlet port;
- c) a pump shaft rotatably disposed in the frame for receiving rotational power from a motor, the pump shaft having at least one substantially circular eccentric lobe disposed thereon, a center of the at least one substantially circular eccentric lobe displaced or offset from a longitudinal axis of the pump shaft;
- d) at least one slide disposed in the frame, the at least one slide operatively configured to move linearly side-to-side within the frame, the at least one slide further comprising a pair of substantially parallel spaced-apart sidewalls;
- e) at least one pony rod assembly operatively coupling the at least one slide to the at least one pump fluid end module;
- f) a connecting rod comprising first and second ends operatively coupling the pump shaft to the at least one slide, the connecting rod disposed between the pair of substantially parallel spaced-apart sidewalls of the at least one slide such that the connecting rod is pivotable relative to the pair of substantially parallel spaced-apart sidewalls of the at least one slide, the first end of the connecting rod rotatably disposed on the at least one substantially circular eccentric lobe, the second end of the connecting rod rotatably pinned to the pair of substantially parallel spaced-apart sidewalls of the at least one slide whereby rotation of the pump shaft causes the at least one slide to move linearly side-to-side that, in turn, causes the at least one pony rod assembly to operate the at least one pump fluid end module;
- and
- g) a support mechanism disposed beneath and operatively coupled to the at least one slide.

- and
- i) a support mechanism disposed beneath and operatively coupled to the at least one slide.
