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.
