Nov. 14, 2017 – The Power Pro ESP pump combines the benefits of the two common types of electric ground water sampling pumps on the market today – the high-powered pump and the disposable pump – into one efficient unit.
The pump, which is made by Q.E.D. Environmental Systems, a subsidiary of Graco Inc., is an all-in-one system with controls integrated directly into the cable reel.
High-powered pumps offer strength, with substantial depth capability, but need a heavy, bulky generator to run, the company said in a press release. Disposable pumps are lightweight and easy to move, but are not as powerful and can be expensive to repair or replace over time.
QED pioneered the methodology of low-flow sampling and used this expertise to develop an electric pump for low-flow sampling with low power consumption and smart-sensor capabilities.
With other electric ground water sampling pumps, it is often necessary to measure the cable and tubing before lowering the pump to achieve the proper depth. The Power Pro ESP pump eliminates this inconvenience with its in-water sensor. 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.
