Standard Flow Foot Valves

The Standard Flow System is the most popular inertial pump. This system is best suited for 1” to 2” ID monitoring wells and can provide lifts of 150 to 200 feet. Flow rates can be as much as 1 gallon per minute.

The Standard Flow System is suitable for a variety of sampling environments. Optional tubing includes low density polyethylene (LDPE) (Canada only) and Teflon (FEP)

The most commonly used foot valve is the 1 inch OD, acetal thermoplastic D-25. Optional foot valves include the stainless steel 3/4" OD SS-19 and the 5/8" OD D-16 and SS-16. 

The Standard Flow System is frequently used because it offers the ability to develop new monitoring well installations and can remove even the most turbid groundwater with no detrimental effect to the pump. Once development is completed the same pump can be used to both purge and sample the well. Since the system is so affordable most customers choose to dedicate the inertial pump to the monitoring well thereby eliminating the need for decontamination.
