High Flow Foot Valves D32
The High Flow System is designed to be used in 2 inch wells or larger where a high pumping rate is desired. This system is also an excellent well development tool in 2 inch piezometers.
Product Description
Consisting of a High Flow valve, either the 1.25" OD, acetal plastic D-32 or the stainless steel SS-32 and a length of 1" OD High Flow tubing usually constructed from HDPE, the High Flow system can provide lift of up to 250-300 feet in 2 inch monitoring wells and flow rates of up to 4 gallons perminute.
recommended devices
The increased weight of the High Flow System makes manual operation difficult beyond 60 feet and use of the Waterra Hydrolift II or PowerPump 2 is strongly recommended.
well development
This system can also be adapted for well development by installing a SBD-25 Surge Block to the D-32 footvalve. This device causes the pump to simultaneously surge and pump, removing fine material from the well and well screen.
