High Seizure Resistance Hydraulic Vane Pump For Geological Drilling Equipment
Features:
Features:
1.To adopt balanced hydraulic for the struction of intra-vane and ten-vane design, higher presure,top to 21Mpa.
2.To adopt floating structure for side plate,it will do a compensation for end-face clearance by automatic,so that even the pump under high pressure it can maintain a high volumetric effciency.
3.The side plate is made of dual-metal material, it improved the seizure resistance,and so that the life of pump will be longer.
