Water Quality Testing Equipment > Low Flow Sampling Pumps
 
Also See Our Proactive 12 Volt Electric Submersible Pumps - (Click To Left)
 
Low flow pumps are designed for sampling environmental monitoring wells without disturbing the water too much. By keeping the velocity of the water in the well low, there is a better chance of obtaining a more representative sample. We have a few different low flow pumps for sale and some for rental. The Grundfos RedifloII 2 inch pump is one of the more popular models as it can pump from depths of almost 300' the rate of flow is variable. If you are not going too deep we have 12 volt models that can hook up to your car battery.
