The piston dispensing system is used to transfer materials that in our case we classify as unsuitable for pumping with gear pumps, mostly materials with very high or low viscosity. The dispensing section is built of two separate modules, configured according to individual user requirements. The operation of the entire system is based on suction and discharge of the medium in one cycle of the actuator. When the actuator retracts, the material is suctioned into the cylinder, while when the actuator is pushed out, the material is pumped into the mixing head. The actuator position sensors used enable process control to ensure high dispensing accuracy.
