  • Patent number: 12180980
    Abstract: In some implementations, a controller may monitor, in connection with a fluid pump driven by a motor that is controlled by a variable frequency drive and over a time period, a torque of the motor to obtain torque data, a speed of the motor to obtain speed data, and a pressure of the fluid pump to obtain pressure data. The controller may determine that the fluid pump is associated with a leak of a particular severity level based on the torque data indicating a deviation that satisfies a first threshold, the speed data indicating a deviation that satisfies a second threshold, and the pressure data indicating a deviation that satisfies a third threshold. The controller may perform at least one operation based on the particular severity level of the leak.

  • Patent number: 12038009
    Abstract: The water-conserving liquid ring vacuum pump system receives the output from a water ring vacuum pump, removes the air and contaminants from the water, and returns the clean water to the make-up water port on the pump, thereby saving most of the water that would normally be discarded. Friction in the pump also heats the water, so the system is designed to cool the water as well.
