3 R /08.97 Fixed Displacement Motor 2FM (2FM) echnical Data Hydraulic fluid We request that before starting a project detailed information about the choice of pressure fluids and application conditions are taken from our catalogue sheets R (petroleum oil), R (environmentally acceptable hydraulic fluids) and R (fire resistance fluids, HF). When using HF- or environmentally acceptable hydraulic fluids possible limitations for the technical data have to be taken into consideration. If necessary please consult us or your fluid supplier (please indicate type of the hydraulic fluid used for your application on the order sheet). Operating viscosity range In order to optain optimum efficiency and service life, we recommend that the operating viscosity (at operating temperature) be selected from within the range: Optimum operating viscosity ν opt = SUS ( mm 2 /s) referred to the loop temperature (closed circuit) or reservoir temperature (open circuit). Viscosity limits he limiting values for viscosity are as follows: Sizes ν min = 42 SUS (5 mm 2 /s) short term at a max. perm. temperature of t max = 240 F (115 C) ν max = 7400 SUS (1600 mm 2 /s) short term on cold start (t min = -40 F / C) Sizes ν min = 60 SUS (10 mm 2 /s) short term at a max. perm. leakage oil temp. of t max = 195 F (90 C) ν max = 4600 SUS (1000 mm 2 /s) short term on cold start (t min = -13 F / -25 C) Please note that the max. fluid temperature is also not exceeded in certain areas (for instance bearing area). t temperatures of -13 F up to -40 F (-25 C up to -40 C) special measures may be required for certain installation positions. Please contact us for further information.

Notes on the selection of the hydraulic fluid In order to select the correct fluid, it is necessary to know the operating temperature in the loop (closed circuit) or the reservoir temperature (open circuit) in relation to the ambient temperature. he hydraulic fluid should be selected so that within the operating temperature range, the operating viscosity lies within the optimum range (ν opt ) (see shaded section of the selection diagram). We recommend that the highest possible viscosity range should be chosen in each case. Example: t an ambient temperature of X, the operating temperature (closed circuit: loop temperature; open circuit: reservoir temperature) is 140 F (60 C). Within the optimum operating viscosity range (ν opt ; shaded area), this corresponds to viscosity grades VG 46 or VG 68. VG 68 should be selected. Important: he leakage oil (case drain oil) temperature is influenced by pressure and motor speed and is always higher than the circuit temperature or the reservoir temperature. However, at no point in the system may the temperature exceed 240 F (115 C) for sizes or 195 F (90 C) for sizes If it is not possible to comply with the above conditions because of extreme operating parameters or high ambient temperature, please consult us. Filtration he finer the filtration the better the achieved purity grade of the pressure fluid and the longer the life of the axial piston unit. o ensure the functioning of the axial piston unit a minimum purity grade of: 9 to NS to SE 18/15 to ISO/DIS 4406 is necessary. t very high temperatures of the hydraulic fluid (195 F to max. 240 F / 90 C to max. 115 C, not permissible for sizes !) at least cleanless class 8 to NS to SE 17/14 to ISO/DIS 4406 is necessary. If above mentioned grades cannot be maintained please consult us. Direction of flow clockwise rotation to counter-clockwise rotation to Speed range here is no limitation on minimum speed n min. If uniformity of rotation is required, however, speed n min should not be allowed to fall below 50 rpm. See table on page 7 for max. permissible speeds. Installation position ny installation position possible. he motor housing must be filled with fluid prior the commissioning, and must remain full whenever it is operating. For extensive information on installation postition, please consult our data sheet R before completing your design work. Symbol, Service line ports Drain port 4

It must then be noted that only a port plate with ports at side is then available (port plate 52). he flushing and boost pressure relief valve has a fixed setting of 230 psi / 16 bar (the setting of the primary boost pressure relief valve must be noted) and is used to safeguard the minimum boost pressure. fixed flow of fluid is taken via an orifice from the low pressure side of the circuit and fed into the motor housing. his flow is then passed back to reservoir with the case drain fluid. Fluid thus removed from the closed circuit must be made up by means of the boost pump. Different orifice sizes may be used to select varying flows of flushing fluid. Flows (at low pressure p = 365 psi / 25 bar) * Size Flow Orifice No. 45, 56, gpm (3,5 L/min) / , gpm (5 L/min) / , gpm (8 L/min) / , gpm (10 L/min) / gpm (10 L/min) * Standard flushing volumes (for sizes flushing volumes of gpm / 3,5-10 L/min can be supplied. If a flushing volume different from the standard flushing volume is required, please indicate the requested orifice in clear text when ordering). 2 1 () () Long-Life bearings (L) (sizes ) (for high life expectancy and use of HF-fluids) he outer dimensions of the axial piston motors are identical to standard design (without long life bearings). he change from standard design to long life bearing system is possible.
