Patent ID: 7407371

Claim:
A centrifugal multistage stage pump adapted to use between 10 and 60 volts of input DC power comprising: a. a pump body comprising a longitudinal axis, an inlet for receiving a fluid from a first location and an outlet for discharging a pressurized fluid to a second location; b. a hydraulic assembly disposed within the pump body and adapted to pressurize the fluid to form the pressurized fluid, wherein the hydraulic assembly comprises: i. a first diffuser comprising a first impeller; and ii. a second diffuser comprising a second impeller, wherein the pressurized fluid flows centrifugally from the first diffuser to the second diffuser; c. an induction motor operably connected to the first impeller and the second impeller; d. a first circuit board inverter disposed within the pump body; e. a microcontroller disposed on the first circuit board inverter, wherein the microcontroller comprises an operating system with memory and is adapted to control the induction motor; f. a pressure transducer disposed within the pump body; g. a heat sink adjacent the first circuit board inverter adapted for removing heat from the first circuit board inverter and transferring it to the pressurized fluid; h. a control panel operably connected to the first circuit board inverter and the microcontroller; i. a mounting system adapted for rotation of the pump body around the longitudinal axis; and j. software imbedded within the memory comprising: i. protection features adapted for emergency shutoff; ii. monitoring features adapted for monitoring pressure, temperature and power levels; and iii. control features adapted for control of motor speed, start and stop of motor.
