The Basic Components Of LSR Dosing system

Distribution of high viscosity LSR materials requires the use of pressure plate pumps and associated components. The pressure plate pump is provided by a pneumatic, electric or hydraulic driven cylinder, which passes through the pressure plate into the material container and pressurizes the silicone under the pressure plate. The pressure forces the viscous silicone into the flow channel at the center of the pressure disc and out through the lower rigid body of the pump. The sealing ring on the pressure plate effectively prevents material leakage and prevents contaminants from entering the container.
A&B and other component hoses carry material from the metering pump to the manifold assembly. The manifold is equipped with a check valve for each materials to prevent backflow, which can leave vulcanized rubber in the hose. Check valves also isolate manifold pressure from individual pump pressure, which is useful in monitoring pump performance.
A static mixer should be included in the system. Although the injected screw has some mixing effect, it is best to mix well before the material enters the screw. The third and fourth materials may also require additional mixing.
The water-cooled jacket can be used for all components in the mixed material flow.
