Radially coupled pump systems for pressurizing fluid in closed loop systems

A pump system to pressurize a fluid within a closed loop transport bus, the pump system comprising:

• an electric motor including a rotor shaft and a stator, wherein the stator is to induce a first angular velocity of the rotor shaft;
• a pump including an impeller coupled to an impeller shaft, wherein the impeller shaft is to rotate at a second angular velocity, and wherein the pump is to increase a kinetic energy of the fluid;
• a driver wheel fixed to the rotor shaft, wherein the driver wheel is radially connected to a follower wheel;
• and
• a co-axial magnetic coupling to couple at least one of the follower wheel to the impeller shaft or the driver wheel to the rotor shaft, wherein the co-axial magnetic coupling includes an outer hub, an inner hub, and a barrier can, the barrier can to hermetically seal a portion of the pump system from the fluid.

A pump system to pressurize a fluid within a closed loop transport bus, the pump system comprising:

• means for rotating a driver wheel, wherein the means for rotating is to exert a first torque on the driver wheel, and wherein the means for rotating is to generate a first angular velocity of the driver wheel based on the first torque;
• means for accelerating a flow rate of the fluid, wherein the means for accelerating is to rotate an impeller shaft at a second angular velocity based on a second torque;
• means for converting the first torque of the driver wheel into the second torque of a follower wheel, wherein the means for converting is to generate the second angular velocity of the follower wheel based on the second torque;
• and
• means for connecting at least one of the follower wheel to the impeller shaft or the driver wheel to a rotor shaft, wherein the means for connecting is to hermetically seal a portion of the pump system from the fluid.
