GPC4 Series High Pressure Gear Pumps GPC4 Multiple Gear Pumps
GPC4 Series high pressure gear pumps have the advantageous features of the axial flexible compensation and radial hydraulic balance. This series pumps can also be combined into multiple pumps to meet the special needs. GPC4 gear pumps can provide various kinds of mounting flanges, shaft ends and inlet & outlet oil connection with SAE and Chinese standards. They are widely used in the construction, walking machinery and other hydraulic systems.

Notes:
The maximum speed at rated pressure is defined by the maximum displacement. The minimum speed at rated pressure is defined by the minimum displacement. 2. Calculation of mass of double pump: 7.5+a1+a2; Calculation of mass of triple pump: 10.5+a1+a2+a3; calculating formula of mass of quadruple pump: 13.5+a1+a2+a3+a4;The weight is reduced by 0.5kg for flange cover SAE B and NO.2.; 3. Load of each kind of pump should not exceed the number in the table. (P: pressure, V: displacement) 4. The input power of each stage pump adds up to the total input power.
