The model SD7200 consists of two primary subsystems: A pump drive module and a fluid delivery module.
The pump drive module is 100% pneumatically operated to minimise explosion hazards associated with solvent dispensing. Plant line air is coupled to the dispenser with a standard quick disconnect fitting. A dual acting air cylinder is controlled by an air bearing, pneumatically piloted control valve. This bi-directional valve is speed controlled by a precision integral regulator to allow repeatable metering of solvent.The fluid delivery module consists of a primary reservoir, a positive displacement pump, a secondary reservoir and a solvent applicator. Solvent is transported from the primary reservoir to the secondary reservoir by a fully submerged piston pump. This pump is actuated by the pump drive module described above. The solvent is then gravity fed from the secondary reservoir into the application area. A solvent film is uniformly applied to the desired component by transfer from non-clogging porous materials contained in the applicator.
