Abstract
A mounting assembly mounts a fluid end unit to a power end unit and includes first and second end members, and a coupling. A first end of the first end member is a threaded shaft configured to be received in a mounting aperture of a power end unit. A first end of the second end member is a threaded shaft configured to be received in a mounting aperture of a fluid end unit corresponding to the mounting aperture of the power end unit. The coupling couples and extends the first end member and the second end member and may be removed therefrom without changing a relative position of the second end member to the first end member.

A mounting assembly for mounting a fluid end unit of a pump to a power end unit of the pump, the mounting assembly comprising:
- a first end member extending between a first end and a second end, the first end of the first end member being a threaded shaft configured to be received in a mounting aperture of a power end unit to couple the first end member thereto;
- a second end member extending between a first end and a second end, the first end of the second end member being a threaded shaft configured to be received in a mounting aperture of a fluid end unit corresponding to the mounting aperture of the power end unit to couple the second end member thereto;
- and
- a coupling configured to removably couple to and extend between the second end of the first end member and the second end of the second end member.
A connector for mounting a fluid end unit of a pump to a power end unit of the pump, the connector comprising:
- a first member having a first threaded shaft and a second threaded shaft, the first threaded shaft being configured to couple to the power end unit, and the second threaded shaft being coaxial with and extending away from the first threaded shaft;
- a second member having a first threaded shaft and a second threaded shaft, the first threaded shaft being configured to couple to the fluid end unit, and the second threaded shaft being coaxial with and extending away from the first threaded shaft;
- and
- a cylindrical connector having a first connector member and a second connector member that each form approximately one half of the cylindrical connector and which cooperatively define a first threaded bore at a first axial end of the connector for coupling to the second threaded shaft of the first member, and cooperatively define a second threaded bore at a second axial end of the connector for coupling to the second threaded shaft of the second member;
- wherein the connector is configured to extend laterally from the power end unit to support the fluid end unit.
A pump comprising:
- a power end unit comprising a first structural member and a first reciprocating member, the power end unit being configured to output mechanical energy by reciprocally moving the first reciprocating member relative to the structural member, and the first structural member including a plurality of first mounting locations;
- a fluid end unit comprising a second structural member and a second reciprocating member configured to be moved reciprocally by the first reciprocating member relative to the second structural member, the fluid end unit being configured to pump a liquid via the second reciprocating member, and the second structural member including a plurality of second mounting locations that are each aligned with an associated one of the first mounting locations;
- and
- a mounting system that mounts the fluid end unit to the power end by coupling the first structural member to the second structural member, wherein the mounting system includes a plurality of mounting assemblies that each comprise:
- a first end member removably coupled to the first structure at one of the first mounting locations;
- a second end member removably coupled to the second structure at the second mounting location associated with the first mounting location;
- and
- a coupling including a first end and a second end, the first end being removably coupled to the first end member, and the second end being removably coupled to the second end member.
