DESCRIPTION
Reliable Hydraulic Oils have long service life and are recommended for hydraulic systems due to excellent lubrication characteristics and wide variety of circulation systems of industrial and automotives equipments. These are made from high viscosity index; chemically stable base stocks, which are further, fortified with antioxidants, anticorrosion, antiwear and antifoam additives. They meet the requirements of very high presser systems and also of systems where high pump speeds are encountered.
BENEFITS
Reliable Hydraulic oil grades possess the following characteristics: -
• Right viscosity to satisfy the demands of the hydraulic pump and the designed system.
• High viscosity index to restrict viscosity changes under operating conditions.
• Good film strength and antiwear properties to Minimise wear of pumps, valves, cylinders, pistons etc.
• Maximum demulsibility to allow entrained water to settle down.
• Excellent corrosion resistance to prevent rusting and corrosion of metal parts.
• Resistance to foaming to ensure prompt and efficient functioning.
• High chemical stability to ensure long and trouble free service life.
Hydraulic oil 32, 46, 68, 100, 150 meet the requirements of IS: 10522-1983 (Reaffirmed 1993) and these oils pass Vickers V-104C vane pump test.
APPLICATIONS
Reliable Hydraulic oils EP grades are recommended tor lubrication of industrial machinery and hydraulic systems fitted with wide variety of pumps operating under moderate conditions. These grades are also recommended for circulation, splash, bath and ring oiling systems. The adaptability of Reliable Hydraulic oil EP grades greatly reduces lubrication costs and ensure smooth and trouble free operation.
The recommended maximum bulk fluid temperature is approximately 80 oC. However continuous operation at this temperature may reduce service life of the oil. Reliable Hydraulic oil EP grades are not recommended for use in hydraulic systems containing silver and cadmium plated components.
