  • Publication number: 20180180042
    Abstract: A fully submergible dual-action cryogenic pump has a housing configured to receive a liquid into the interior compartment when submerged in the liquid. The housing includes an interior compartment having an inner peripheral surface, a first end, and a second end. A free piston having a first end, a second end, and an outer peripheral surface is contained within the interior compartment. A first compression chamber is formed between the first end of the free piston and the first end of the interior compartment. A second compression chamber is formed between the second end of the free piston and the second end of the interior compartment. An electromagnetic drive is configured to reciprocate the free piston. A sealing area is formed by the outer peripheral surface of the free piston sealing with the inner peripheral surface of the interior compartment.

  • Publication number: 20180180035
    Abstract: A pumping system is disclosed for use in pressurizing a cryogenic fluid. The pumping system has a motor, an arm reciprocated by the motor, and a reciprocating pump configured to be submerged in a liquid. The pump includes a piston. The pumping system also has a rod mechanically coupled to the piston and a magnetic coupling configured to reciprocate the rod in response to the reciprocation of the arm. The magnetic coupling includes an outer magnetic portion associated with the arm and an inner magnetic portion associated with the rod.

  • Publication number: 20150377419
    Abstract: A method of controlling a liquefied natural gas system is provided. The method includes providing a first pump in association with a tank. The method includes connecting a second pump downstream of the first pump through a supply line. The method further includes providing a valve assembly in a return line provided downstream of the second pump. The method includes connecting an adjustable restrictor in the return line, the adjustable restrictor positioned downstream of the valve assembly. The method further includes cooling the second pump by operating the valve assembly in an open configuration to fluidly connect the adjustable restrictor and the second pump. The method also includes providing a flow of the liquefied natural gas to the second pump for controlling an operating temperature of the second pump. The method includes selectively operating the adjustable restrictor to control a suction pressure associated with the second pump.
