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 density polyethylene (HDPE) tubing, the High Flow system can provide lift of up to 90m in 2 inch (50mm) monitoring wells and flow rates of up to 15 lpm.
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.
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.
