This 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. The generator-style frame is made of stainless steel for extended outdoor use and resistance against corrosive environments.
