Waterra D-16 Inertial Pump Foot Valve, Standard Flow
Waterra D-16 Foot Valve, Standard Flow
The Waterra D-16 Standard Flow Inertial Pump foot valve is made of acetal thermoplastic and has a 5/8 inch OD (16 mm). The D-16 is used with Waterra Standard Flow HDPE or LDPE Tubing (⅝” X ½”). The tapered male thread self taps into the polyethylene tubing making a semi-secure connection. If this valve is used in a deep monitoring well (> 50’), a stainless screw may be driven through the poly tubing and into the plastic valve’s threading to permanently attach the valve to the tubing.
Contains No PFAS.
A Waterra D-16 Inertial Pump can be operated by hand with the Waterra Lever Pump or with the use of a powered Waterra tubing actuator such as the Hydrolift-2. The Standard Flow Inertial Pump System is the most popular Waterra Inertial Pump. This system is best suited for use in 2 inch monitoring wells and can provide lifts of up to 150 feet. Flow rates are a function of pumping speed and lift requirements and can be as much as 1 gallon per minute.
The D-16 Foot Valve is designed for use in narrow diameter wells or 2” monitoring wells where access is restricted. The low cost, reliability and durability make the Waterra Inertial Pump an excellent choice as a dedicated monitoring well pump.
