  • Patent number: 10533549
    Abstract: The bilge pump safety system comprises a bilge pump, a primary switch, a monitor switch, and a control system. The primary switch is a first float switch that controls the operation of the bilge pump based on the level of liquid accumulated in the bilge that is protected by the bilge pump. The monitor switch is a second float switch installed within the bilge such that the monitor switch mimics the operation of the primary switch. By mimic is meant that: 1) when the primary switch is closed the monitor switch is closed; and, 2) when the primary switch is open the monitor switch is open. The control system simultaneously monitors the status of both the primary switch and the monitor switch. In situations where the operation of the monitor switch does not mimic the primary switch, the control system generates a message to an appropriate authority.

  • Patent number: 10533570
    Abstract: An opposing impeller arrangement, for using in an opposed impeller pump, features a combination of a stage 1 impeller arrangement and a stage 2 impeller arrangement having opposing impellers and different impeller and wear ring arrangements. The stage 1 impeller arrangement may include a stage 1 impeller and a stage 1 wear ring, and be configured to receive an input fluid flow and a pump stage 1 fluid flow. The stage 2 impeller arrangement may include a stage 2 impeller and a stage 2 wear ring configured to receive the pump stage 1 fluid flow and provide a pump stage 2 fluid flow, and may also include a stage 2 wear ring undercut configured between the stage 2 impeller and the stage 2 wear ring to offset generated axial thrust in the opposing impeller pump, based upon the different impeller and wear ring arrangements.

  • Patent number: 10533571
    Abstract: A system having a variable diameter impeller device that is operable for reducing an energy consumption of a rotating fluid or gas pump by increasing the impeller diameter as a speed of the rotating fluid or gas pump increases and decreasing the impeller diameter as the speed decreases. An extendable vane arrangement is configured to move along an elongated curved or sloping slot, the movement along the elongated curved or sloping slot is operable for increasing and decreasing a diameter of the impeller device. A spring arrangement having a first end and a second end extends and retracts to dynamically increase or decrease a diameter of the impeller device.

  • Patent number: 10533578
    Abstract: A well pump assembly includes a centrifugal pump having a housing with a cylindrical internal side wall. Upper and lower diffusers are located in the housing. A metal-to-metal seal seals an upper end portion of the lower diffuser to the lower end portion of the upper diffuser. The seal also has an outer surface that frictionally engages the internal side wall of the housing. The seal is energized in response to an axial force exerted between the upper and lower diffusers. One version has a metal seal ring located in mating recesses on the outer walls of the diffusers. Another version includes an inner lip on one of the end portions of the diffusers that extends within and deflects an outer lip on the other of the end portions of the diffusers.

  • Patent number: 10533582
    Abstract: An energy storage and regeneration system that converts irregular, non-constant, and variable input power to regular, constant, and controlled output power using hydraulics whereby the irregular input power is used to pump hydraulic fluid into an accumulator array where it is stored pressurized. Energy is released in a controlled fashion using a hydraulic motor operated by the pressurized hydraulic fluid from the accumulator array, in accordance with the specified power demand. One or more power units may be deployed depending on the amount of energy required at the output. Each power unit includes a hydraulic motor and associated floating accumulator assembly whose internal pressure is controlled to maintain a substantially constant pressure differential across its associated motor.
