The GOLGASOR (GGS) is a small, reliable, and robust propulsion system designed for the dense-phase conveying of powders and granules. Its simple and compact geometries make it adaptable to various situations, ensuring the effectiveness and efficiency of dense-phase conveying even in tight spaces where other systems cannot be installed. With minimal dimensions and an operating pressure always below 2 bar, the GOLGASOR propulsion system does not fall under the pressure vessel category subject to certifications mandated by the PED directive. The simple and efficient feeding system ensures a reduced price and extraordinary ease of use
