RENOLIN B 68 HVI PLUS - 20L - Fuchs - Hydraulic Oil - 1697020
Premium, high viscosity index hydraulic oil.Superior additives provide improved ageing resistance, corrosion protection and wear protection.
The function of hydraulic oil pumps can often be improved irrespective of the machinery driven, because they are isolated from the variables found at the workplace. A major factor in the performance of hydraulic systems is the fluid medium. This absorbs a relatively large amount of energy when the pump is started up because of the high internal resistance of hydraulic oil.
Excessive friction also occurs if the oil’s viscosity is too low and this leads to wear. Such conditions can cause breakdowns. FUCHS has developed a series of so-called “low friction” oils, which reduce energy consumption and wear when hydraulic pumps are started up.
These products also improve reliability and eliminate breakdowns caused by insufficient or excess viscosity, both problems associated with normal HLP hydraulic oils.

Application Excellent viscosity – temperature behaviour The manufacturers of hydraulic equipment publish threshold values for start up, minimum and optimum viscosity in their operating handbooks. The high viscosity of normal hydraulic oils consumes large amounts of energy when systems are started up and the time required for the oil to reach its operating viscosity is very long. Another problem with normal hydraulic oil is that insufficient viscosity at high operating temperatures can cause wear in bearings and pumps. The RENOLIN B HVI PLUS series of oils reduce these start up problems and form stable, protecting films at high operating temperatures which increases the reliability and service life of hydraulic systems. This superior high temperature viscosity also improves sealing and reduces leaks to a minimum. Excellent oxidation stability and resistance to ageing Oil temperatures of over 80°C can occur in highpressure systems, especially if the volume of the tank is small. Insufficient oxidation stability can lead to the formation of damaging by products, which acidify the oil. This in turn causes polymerisation, which increases the viscosity of the oil and leaves lacquer-like deposits on valves and control units. The RENOLIN B HVI PLUS series of oils are based on high-grade special raffinates and contain additives, which improve their resistance to ageing. As these are long-life characteristics, they also increase the service life of the products.
