Systems and devices for pumping and controlling high temperature fluids

A pump comprising:

• pump components comprising:
• a pump body made at least in part by a first brittle material;
• a first plate;
• a second plate comprising:
• a fluid inlet;
• and
• a fluid outlet;
• and
• a fluid connection adapter attached to the second plate, the fluid connection adapter being made of a brittle material and comprising:
• a first thread configured to be attached to the fluid inlet or fluid outlet, the first thread being hollow;
• and
• a second thread comprising:
• an aperture configured to receive the end of a pipe having a graphite ferrule that is configured to expand radially to form a seal between the pipe and the second thread in response to an axial force;
• and
• threading configured to receive a nut;
• wherein the pump body comprises:
• a closed face having an aperture for receiving a shaft;
• an open face;
• and
• a chamber disposed between the closed face and the open face, the chamber having a first side, a second side, and housing at least a first gear;
• wherein the first plate is positioned externally to the closed face of the pump body, and having an aperture for receiving a shaft;
• wherein the second plate is attached to the pump body at the open face such that the chamber is enclosed, and the fluid inlet is in communication with the first side of the chamber and the fluid outlet is in communication with the second side of the chamber;
• and
• wherein the pump is configured to operate at temperatures between 500° C. and 3000° C.

A pump and motor system comprising:

• a pump comprising:
• pump components comprising:
• a pump body made at least in part by a first brittle material;
• a first plate;
• a second plate comprising:
• a fluid inlet;
• and
• a fluid outlet;
• wherein the pump body comprises:
• a closed face having an aperture for receiving a shaft;
• an open face;
• and
• a chamber disposed between the closed face and the open face, the chamber having a first side, a second side, and housing at least a first gear;
• wherein the first plate is positioned externally to the closed face of the pump body, and having an aperture for receiving a shaft;
• wherein the second plate is attached to the pump body at the open face such that the chamber is enclosed, and the fluid inlet is in communication with the first side of the chamber and the fluid outlet is in communication with the second side of the chamber;
• and
• wherein the pump is configured to operate at temperatures between 500° C. and 3000° C.;
• and
• a motor configured to operate at temperatures between 0° C. and 300° C.;
• an insulating shaft that mechanically connects the pump to the motor;
• a motor shaft attached to the motor;
• the insulating shaft positioned between a pump shaft and the motor shaft, the insulating shaft comprising a second coupler configured to rotatably engage a first coupler of the pump shaft;
• a flexible joint that attaches the insulating shaft to the motor shaft;
• and
• a bearing mount comprising a plate with an aperture configured to support the insulating shaft, wherein the bearing mount enables insulating shaft to be angularly flexible but axially constrained;
• wherein the first gear is attached to a pump shaft extending out of a body of the pump, and the pump shaft terminates in the first coupler;
• and
• wherein the pump is distanced from the motor such as to thermally isolate the pump from the motor such that the motor operates in its temperature range while the pump simultaneously operates in its temperature range.
