This document describes Pump Guru, an intelligent pump controller that can control and protect direct start or star delta three phase submersible pumps from 0.75KW to 75KW. Pump Guru uses sensors to protect against dry run without needing probes in the well. It displays voltage, current, power usage, water levels and alarms to help prevent issues and plan maintenance. Additional features include timers, remote monitoring options, and protections for issues like phase loss or voltage problems. Pump Guru controllers are available for single or three phase pumps in metal or plastic enclosures.
