Vane Pumps Double Pump HQ22 Series 23 #DriveLineHarmony www.jbj.co.uk/vane-pumps.html P1 P2 S Technical caracteristics (P1 and P2 sections) General description Fixed displacement vane pump, hydrau- lically balanced, with capacity determi- ned by the type of cartridge used and the speed of rotation. The pump is avai- lable in several versions with rated capa- city from 52 to 131 l/min (from 14 to 35 gpm) at 1000 rpm and 7 bar pressure. Hydraulic fluids: antiwear high quality mineral oils or fluid based on phosphate ester. Viscosity range: (with mineral oil) : from 13 to 860 cSt. (13 to 54 cSt. recommended). Filtration: for the inlet - not less than 149 micron abs., for the return line - 25 micron abs. or smaller (with synthetic fluids: for the return line - 10 micron abs. or smaller). 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.
