he Waterra High Flow System is designed to be used in 2" monitoring wells or larger where a high pumping rate is desired or where very deep wells are encountered. This system is also an excellent
well development tool in 2" piezometers.
This system consists of a High Flow foot 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 lifts of up to 250-300 feet in 2 inch monitoring wells and flow rates of up to 4 gallons per minute.
It is recommended to use an automated actuator with the High Flow System. The Hydrolift-2,  PowerLift-3, PowerPack-PP1 or Power- Pump-2 are all recommended for use with the High Flow System.
The PowerPump-2 is the most powerful actuator produced byWaterra and will operate this system to its maximum limits.
As a general guide, in most 2" monitoring wells, the High Flow System D-32 will usually produce
a flow rate of about 1 to 3 gallon per minute, given 20 to 30 feet of valve submergence.
The High Flow System has a substantial lift capacity in 2" diameter piezometers. Some customers
have reported lifts approaching 300 feet.
This system is designed to be used in 2" wells or larger, where a high pumping rate is desired. The High Flow System can provide lifts of 250 to 300 feet.
RECOMMENDED DEVICES
The High Flow System is considerably heavier than the Standard Flow system and consequently is not nearly as suitable for manual operation.The High Flow System can be manually operated in monitoring wells up to a maximum depth of about 60 feet, depending on the operator's strength and
endurance.
The greatest performance improvements are realized with the use of theWaterra Hydrolift-2, PowerLift-3, PowerPack-PP1 or PowerPump-2.The use of one of these automated actuators greatly improves the well development capacity of the inertial pump.The automated actuators are also recommended when substantial purge volumes are required.
