Low-pressure feed systems, such as diaphragm pumps or pressure vessels, are used to supply the material into the positive displacement piston metering pumps. Pressure tanks can be mounted onto the machine chassis, or a remote bulk feed unit is available for feeding directly from 55-gallon drums.
The pumps are driven by a single air motor. A lever system connects the pumps and the drive. The pump for the A component is fixed to the lever system and shares the same stroke length as the drive motor. The pump for the B component is adjustable along a lever system providing a variable stroke length, which is used for the fine adjustment of the mixing ratio.
The ECONO-MIX is typically fitted with our standard two-component static mixing system that includes a twin snuffer valve combined with a disposable static mixer. The valve contains an infinitely adjustable “snuff back” effect to avoid dripping after metering has finished. Should mixed material be allowed to cure in the mixer, it can be replaced simply and inexpensively, thus avoiding a time-consuming, expensive, and environmentally damaging solvent flushing cycle.
Optionally, we can offer both dynamic mixers and/or dynamic static mixer valves where the material requires an aggressive blending cycle necessary to achieve its proper mix.
