Simple, robust and reliable. The Perma Classic can be used in virtually any application with ambient temperatures from 0 ° C to + 40 ° C. Depending on the conditions of use, a lubricant volume of 120 cm³ in 1, 3, 6 or 12 months is issued.The reliable operation is based on an electrochemical reaction. The actuator screw is screwed into the lubrication system and the eyelet is removed. The gas generator generates a pressure of up to 4 bar, which moves the piston forward and brings lubricant to the lubrication point. The Perma Classic has an approval for explosion safety and can be used in the mining industry.
