WELCO CALIBER HLP grades are premium quality lubricating oils formulated with high quality base stock and carefully selected additives. WELCO CALIBER HLP grades offer outstanding high viscosity index, anti-wear properties, excellent oxidation stability and a high FZG rating. the product is zinc free and ash less. The use of WELCO CALIBER HLP fluids results in improved energy efficiency.

WELCO CALIBER HLP is a high-performance hydraulic fluid based severely hydro treated base stocks. The unique anti wear additive system. The additive system is thermally stable and resists hydrolysis in the combined presence of thermal, mechanical and chemical stress.

Used in hydraulic systems, enclosed gear boxes, chain drives, compressors, vacuum pumps, mining machinery, machine tools, circulating oiling systems etc., wherein oil is recirculated and used for extensive periods. Specially recommended for sophisticated high performance electro-hydraulic or numerically controlled systems. It is also recommended as a control fluid for certain governor systems where silver/ cadmium coated surfaces call for fluids which are zinc free. It is also used in hydraulic systems in aluminium processing/ rolling where zinc based hydraulic oils can form surface stains. It is recommended for all applications where strict environment concerns restrict use of products containing zinc & other metals.

WELCO CALIBER HLP SERIES are specially formulated for use in hydraulic system employing high performance pumps. These oils possess excellent oxidation, demulsibility characteristics & high FZG rating. The product is further fortified with rust and foam inhibitors.

WELCO CALIBER HLP SERIES oils have a long service life and are recommended for hydraulic systems due to excellent lubrication characteristics and a wide variety of circulation systems of industrial and automotive equipment. These oils are also used for compressor crankcase lubrication but are not used for lubrication of rem for a high-pressure hydraulic system.
