Double acting pump design utilizing two rotating discs

A pump, comprising:

• a shaft;
• two parallel rotating discs mounted on the shaft, wherein each rotating disc is configured to rotate with the shaft, and wherein each portion of a first of the two rotating discs maintains a fixed distance from a corresponding portion of a second of the two rotating discs during rotation of the two rotating discs with the shaft;
• two outer housings and two outer housing covers, wherein each outer housing combines with an outer housing cover to form a sealed chamber, wherein one of the two parallel rotating disc is within each sealed chamber, and
• at least one double acting fluid end arranged in a radial pattern between the two parallel rotating discs wherein the radial pattern is defined as a measured distance away from a center of the shaft, and
• wherein each double acting fluid end comprises:
• a block, each block including a void;
• each block including a piston located within the void of the block,
• the piston configured to translate from a first position to a second position within the void;
• a first housing connected to the block, the first housing having a suction side and a discharge side, the first housing configured to channel a fluid;
• a second housing connected to the block, the second housing having a suction side and a discharge side, the second housing configured to channel the fluid;
• at least a first suction check valve and a first discharge check valve located in the first housing;
• at least a second suction check valve and a second discharge check valve located in the second housing;
• wherein the sealed chambers are arranged on the shaft such that their outer housing covers face each other;
• and
• wherein each piston extends through the two outer housing covers and between the two rotating discs.

A pump, comprising:

• a shaft;
• two parallel rotating discs mounted on the shaft, wherein each rotating disc has an internal bore that includes a spline, wherein each rotating disc engages the shaft at the respective spline so as to rotate with the shaft, and wherein each portion of a first of the two rotating discs maintains a fixed distance from a corresponding portion of a second of the two rotating discs during rotation of the two rotating discs with the shaft;
• two outer housings and two outer housing covers, wherein each outer housing combines with an outer housing cover to form a sealed chamber, wherein one rotating disc is within each sealed chamber;
• a thrust bearing mounted between each rotating disc and its respective outer housing and configured to support loads developed during rotation of the respective rotating disc;
• and
• at least one double acting fluid end arranged in a radial pattern between the two parallel rotating discs, wherein the radial pattern is defined as a measured distance away from a center of the shaft, and
• wherein each double acting fluid end comprises:
• a block, each block including a void;
• each block including a piston located within the void of the block,
• the piston configured to translate from a first position to a second position within the void;
• a first housing connected to the block, the first housing having a suction side and a discharge side, the first housing configured to channel a fluid;
• a second housing connected to the block, the second housing having a suction side and a discharge side, the second housing configured to channel the fluid;
• at least a first suction check valve and a first discharge check valve located in the first housing;
• at least a second suction check valve and a second discharge check valve located in the second housing;
• wherein the sealed chambers are arranged on the shaft such that their outer housing covers face each other;
• and
• wherein each piston extends through the two outer housing covers and between the two rotating discs.
