B1 single pump Fixed displacement vane pump, hydraulically balanced, with capacity determined by the type of ring used and the speed of rotation. The pump is available in eight different displacements, from 3.29 cc to 22.8 cc. General description Hydraulic fluids: mineral oils, phosphate ester based fluids, water emulsions in oil, water-glycol 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 +0,35 bar (-2.5 + 5 psi) , (with synthetic fluids and water-in-oil emulsion) : from -0,10 to +0,35 bar (-1.5 + 5 psi) Operating temperature: with mineral oil -10°C to +70°C (+30°C to +60°C recommended),with water based fluids +15°C to +50°C. Drive: direct and coaxial by means of a flexible coupling.
