HYDRAULIC MOTORS HYDRAULIC FLUIDS RECOMMENDATIONS HYDRAULIC FLUIDS We recommend the use of hydraulic oils with anti-wear additives (ISO HM or HV) and minimum viscosity index of 95. Once normal working temperature is reached, oil viscosity must be at least 44 cSt, preferably in the range from 50 to 80 Hydraulic oils meeting Denison MF-O, Vickers M-2952-S I - Pay particular attention if you use HE type oils (ecological fluid) because them can influence the motor seals compatibility, the motor performance and life. Please ask us for advice in case of HE type oils usage. Mineral hydraulic oils...

HYDRAULIC MOTORS GENERAL INFORMATION ON FLOW If several motors or cylinders are operate from a single pump without any means of controlling their individual flows only the motor or cylinder with the lowest pressure requirement would start its work cycle. The motor or cylinder with the next lower pressure requirement would only start when the first unit has completed its work cycle. This mode of operation is normally undesiderable, the total pump flow must therefore be divided into a series of partial flows. This can be obtained Throttles or flow regulation valves in each motor or cylinder...

HYDRAULIC MOTORS Italgroup can provide balancing valves directly assembled on italgroup flow dividers. These valves are assembled together by the utilization of steel pipes supplied by italgroup to minimize the piping and fitting problems (see the next pages INSTALLATION CIRCUIT The use of flow dividers is not complicate if the hydraulic circuit has an appropriate design. Additional installation operations are not necessary. See even the internal pressure drop paragraph for more details. Flow divider application to control three cylinders In some special conditions, for example when the...
