56 Fixed displacement vane pump, hydraulically balanced, with capacity determined by the cartridges used and the speed of rotation. The pump is available in several versions with rated capacities from 87 to 195 l/min (from 23 to 52 gpm) at 1200 rpm and 7 bar. General description Hydraulic fluids: mineral oils, phosphate ester based fluids. Viscosity range (with mineral oil) : from 13 to 860 cSt. (13 to 54 cSt. recommended) . Filtration: for the inlet - 149 micron abs., for the return line - 25 micron abs. or better (with synthetic fluids: for the return line - 10 micron abs. or better) . Inlet pressure: (with mineral oil) : from -0,17 to +1,4 bar (-2.5 to + 20 psi) Operating temperature: with mineral oil -10°C +70°C (+30°C to +60°C recommended) . Drive: direct and coaxial by means of a flexible coupling.
