SEIVIO Gealub L188 screw vacuum pump gearbox grease is made of fully synthetic base oil, compound soap machine thickener, and anti-oxidation, anti-wear and other additives through a special process. It is a special high-performance grease customized for the synchronous gearbox, the core transmission component of the screw vacuum pump. It solves the pain points of precise synchronization, low volatile pollution and long-term lubrication under high vacuum and high-speed meshing conditions, and directly determines the ultimate vacuum degree, operating stability and overall machine life of the pump.
