The PAR 20F&PAR 200F systems are specifically designed to handle various high viscosity materials, utilizing reliable and mature technology to quantitatively and accurately supply single component materials in a wide range of applications. The PAR 20F&PAR 200F equipment uses piston rods and built-in sealed pressure plates to directly extract materials from the raw material barrel. In addition, these devices can also be connected to automation systems to achieve fully automatic or semi-automatic applications.
