Variable vane pump manufacturers and suppliers Model : vdp-sf-12 Delivery at no load (l/min) : 1800rpm:12¡¢1500rpm:10 Pressure adjusting range (kgf/cm2) : 0 to 70 Shaft speed (rpm) : max:1800 ¡¢min:800 Pressure (kgf/cm2) : 70 Weight (kg) flange : 5 cooling circulating pump has build-in pressure setting, maintaining pressure at 3kg/cm2, protect pipe line of cooling system. rapid testes proven , to combine with proper cooler , it performed better cooling efficiency then cooling variable vane pump`s drain by air. aluminum alloy exterior of the cooling pump, with heat-absorbing strong , fast heat dissipation characteristics. by reduce size of reservoir , it could save space and volume of hydraulic oil.At the end , it saved cost. Mounting indusdruction 1.The rotation of vcm-sf pump is clockwise when viewed from the shaft end. 2.The drain pipe id directly connected to the oil tank and the positon must be below the level of oil. 3.Keep the suction pressure within 0.3 bar at the suction port. 4.Pressure adjusting scrow is turned clockwise to increase pressure and counterclockwise to increase flow and counterclockwise to decrease pressure. 5.Flow adjusting screw is turned clockwise to increase flow and counterclockwise to decrease flow. 6.For proper alignment of pump and electric motor shaft , the eccentricity between then must be kept within 0.05 mm and the eccentric angle error between them must be kept within 1¡ã. 7.When pressure is under 70 bar the viscosity os oil must be within 30-50 cst , when pressure is over 70 bar the viscosity of oil must be within 50-70 cst , at the temperature of 40¡ã. 8.When first time operation , the pump should be at no-load state-on delivery side and be repeated on and off the electric motor a number of times to make sure the air have been bled out of the system. Weight (kg) flange : 5 Packing:inside with a small box packaging, outside with a wooden box packaging
