The Low Flow System is designed to be used in small diameter piezometers (usually 1″ ID to 0.75″ ID). It can provide flow rates of up to 1/2 gallon per minute and can lift water from up to 100 feet. It is available with either acetal plastic or stainless steel foot valves and HDPE, LLDPE or FEP tubing. The Low Flow System is also useful for sampling in damaged or obstructed monitoring wells.
