Pump system

A pump, comprising,

• a pump housing defining an interior volume having a fluid end section and a power end section;
• and
• a plunger assembly disposed in the pump housing, the plunger assembly comprising:
• a crosshead disposed within a pump housing and movable along a plurality of rods;
• a plunger extending between the fluid end section and the power end section;
• and
• a sleeve at least partially surrounding the plunger and an end of the crosshead, wherein the sleeve fluidly isolates the power end section from the fluid end section.

A pump system, comprising:

• a first pump having a first fluid end and a first power end;
• a second pump having a second fluid end and a second power end, wherein the first pump is positioned adjacent the second pump such that the first power end abuts the second power end, wherein the first pump and second pump having a total length less than or equal to a roadway width restriction, and wherein the first pump and the second pump each comprise:
• a pump housing defining an interior volume having a fluid end section and a power end section;
• and
• a plunger assembly disposed in the pump housing, wherein the plunger assembly comprises:
• a crosshead disposed in the pump housing and movable along a plurality of rods;
• a plunger extending between the fluid end section and the power end section;
• and
• a sleeve at least partially surrounding the plunger and an end of the crosshead, wherein the sleeve fluidly isolates the power end section from the fluid end section.

A crosshead for use in a pump assembly, comprising:

• an elongated body having a first opening that is parallel to a second opening;
• and
• a plurality of fluid passages formed in the elongated body, the plurality of fluid passages, comprising:
• a first fluid passage in communication with a fluid source;
• a second fluid passage in communication with the first fluid passage, the second fluid passage configured to deliver fluid from the first fluid passage to the first opening;
• and
• a third fluid passage in fluid communication with the first fluid passage, the third fluid passage configured to deliver fluid from the first fluid passage to the second opening.

A crosshead for use in a pump assembly, comprising:

• an elongated body having a first opening that is parallel to a second opening, wherein the first opening is formed at a top of the elongated body and the second opening formed at a bottom of the elongated body, and wherein the first and second openings having equal diameters;
• and
• a plurality of fluid passages configured to deliver fluid to the first opening and the second opening, wherein the plurality of fluid passages is formed in the elongated body, the plurality of fluid passages comprises:
• a first fluid passage in communication with a fluid source;
• a second fluid passage in communication with the first fluid passage, the second fluid passage configured to deliver fluid from the first fluid passage to the first opening;
• and
• a third fluid passage in fluid communication with the first fluid passage, the third fluid passage configured to deliver fluid from the first fluid passage to the second opening.
