  • Patent number: 7407371
    Abstract: A centrifugal multistage stage pumps described herein. The centrifugal multistage pump includes a pump body having 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 and a hydraulic assembly disposed within the pump body and adapted to pressurize the fluid. The pump further includes a motor, a first circuit board inverter disposed within the pump body, a microcontroller disposed on the first circuit board inverter, a pressure transducer disposed within the pump body, a heat sink adjacent the first circuit board inverter, a control panel connected to the circuit board inverter and the microcontroller. The pump has a mounting system adapted for rotation of the pump body around the longitudinal axis. In addition, the pump includes software imbedded within the memory, wherein the software includes protection, monitoring and control the features of the pump.

  • Patent number: 7172704
    Abstract: A method for treating waste water fluid, wherein the method comprises the steps of macerating waste water fluid in a first tank forming a sheared fluid, filtering the sheared fluid to remove solids, forming unfiltered waste water and product water, flowing product water to the first tank when the waste water fluid level is below the product water manifold, flowing the product water to a second tank when the waste water fluid level covers the product water manifold, flowing product water in the second tank into a vented loop to a third tank, diluting fluid in the third tank with raw water from a raw water source forming de-chlorinated water; and removing the de-chlorinated water from the third tank.
