BV21 double pump 32 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 55 to 134 l/min (from 14 to 35 gpm) at 1200 rpm and 7 bar. General description Hydraulic fluids: antiwear high quality mineral oils or fire resistant fluid having same lubrication capacities of the mineral oil. 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),with water based fluids +15°C to +50°C. Drive: direct and coaxial by means of a flexible coupling.
