Hammonds Companies designed the 600 Series Additive Injector, a truck-mounted injector, to inject fluid additives directly into fluid products. Typically used in aviation refuelers as a method of adding customer-required additives to bulk fuel products during the delivery process, the 600 Series has a fluid-powered motor, which borrows just enough energy from the flowing product line to operate a diaphragm additive pump. This energy is used to inject the additive upstream of the fluid motor and aid in blending. As a result, there's no need for electricity, air, pulsars or pressurized additive lines. With only a mechanical pipe connection, the unit doesn't require explosion-proof wiring in hazardous conditions, no concrete work, and no costly site engineering to lay out piping, pumps or skids.
