is a short section of the main water pipeline This
is the upstream end of the short water pipeline section
This is the downstream
end of the short water pipeline section These
valves can be closed to isolate the injector Cam
fittings make it easy to move the injector to another
injection location or for off-season storage Motive
water flows from the main pipeline into the injector via
this hose Motive
water mixed with chemical exits from the injector and
flows back to the main pipeline via this hose Motive
water strainer protects clearances in the pump and venturi
against pipeline debris Reliable,
low maintenance centrifugal pump boosts water pressure
causing motive water to flow through the injector
An electric motor.
Electric motors are available for all supply voltages.
Engine-powered injectors are available for locations where
electricity is not available. Motive
water flows though this venturi, creating vacuum that
sucks liquid chemical into the flowing water. A check
valve in the venturi prevents water from backflowing into
the chemical tank. This
hose brings concentrated chemical into the injector from
the customer’s feed tank (tank not shown) This
strainer protects clearances in the concentrated chemical
pipework path This
flowmeter directly displays the flow rate of the flowing
concentrated chemical. The flowmeter eliminates the need
for a separate calibration tube on the injector.
This metering valve
lets the operator set the rate of injection This
valve prevents unwanted forward flow in the chemical line.
If water pressure is present, the valve opens and allows
the concentrated chemical to flow. If water pressure is
not present, the valve closes and blocks the flow.
frame is made of stainless steel for extended outdoor
use and resistance against corrosive environments. (The
