The CP-20 volumetric barrel emptying system is designed for emptying 25L drums containing medium to high viscosity fluids, such as silicone, adhesives, grease, polymers that cannot flow by themselves. The system consists of an emptying pump (rotor), which regularly pumps highly shear sensitive products. This pump sucks the fluid with the help of a follower plate adapted to the diameter of the drum. The drum vacuum is then used to feed the product to the dosing systems.
