Servo system HLP 150N is an oil which gives good film strength.It has excellent anti-wear properties which minimises the wear in pumps, rings, valves, pistons.As it has high viscosity Index,it restricts the viscosity change under continuous operating conditions. It also gives resistance to foaming which results in better performance.It is generally used in hydraulic systems, compressors, pumps, circulation oiling systems, enclosed gearboxes etc.It fulfills the requirements of DIN 51524 HLP (Part 2) and Cincinnati Machines and Vickers Vane pump test.
