High pressure vane pumps available from jbj Techniques Limited

Hydraulic Vane Pumps High Pressure Single Pump HD03 Series Hydraulic fluids: anti-wear petroleum base, synthetic fluid, water glycols and invert emulsions. Viscosity range / Viscosity index: with anti-wear petroleum base, from 10 to 2000 cSt. (10 to 108 cSt. recommended). Other fluids from 18 to 2000 c.St. (18 to 108 c.St. recomm.). Choose 30 c.St. for max lifetime. Viscosity index: 90° min. Filtration: to maintain contamination level to ISO 18/14 or NAS 1638 class 8. Filters: for the inlet, use strainer with mesh not less than 149 micron abs. (omit strainer with application requiring cold start or when using fire resistant fluids); for the return line - 25 micron abs. or better. Water contamination level: max 0.10% for mineral oil. With other fluids, max 0.05% Intermittent pressure: typically the working time permitted at such pressure is < 30% of the duty cycle. With duty cycles longer than 15 minutes, please contact the technical office of B&C. Minimum inlet pressure: (with mineral oil 10-65 c.St.): 0,8 bar abs. (3 psi abs.). In the biggest displacements of each series and with the highest speeds, is required an higher inlet pressure. Please consult the specific section for details. In case of tandem pump, supply the inlet port with the highest pressure requested among the pump stages. Operating temperature: with “antiwear petroleum base” the permitted temperature is: from -18 to +100° C; with water glycol and “water in oil emulsion”: from +10 to +50°C; with synthetic fluid: from -18 to +70°C; with rapeseed and esters: from -20 to + 70°C. During cold start the pumps should be operated at low speed and pressure until fluid warms up to an acceptable viscosity for full power operation. Drive: direct and coaxial by means of a flexible coupling. Low axial and radial loads allowed. Consult specific section for more detail. Fixed displacement vane pump, hydraulically balanced, with capacity determined by the type of cartridge used and the speed of rotation. The pump is available in 13 different displacements with flows from 16 to 150 l/min (from 4 to 40 gpm) at 1500 rpm and pressure 0 bar. 6
