The Power Pro ESP pump by QED combines the two common types of electric groundwater sampling pumps on the market today, the high-powered pump and the disposable pump, into one unit. QED has developed this electric pump for low-flow sampling with low power consumption and smart sensor capabilities. A green light indicates when the pump has hit water and numbered hash marks on the cable allow for easy measuring past the water line. The sensor also works in reverse to provide run-dry protection. When the sensor no longer detects water, it stops the pump and automatically restarts it when the water level recovers.
