2.3 PV2R Double Vane Pump Characteristics
-
Combined by two single pumps (Common models: PV2R12, PV2R23, PV2R34)
-
Dual independent oil circuits, two pumps can work under different pressure separately
-
Max pressure follows matched single pump; Total flow = Flow of front pump + Flow of rear pump

5. Core Calculation Formulas for Pump Selection
-
Theoretical Flow Rate Q(Theoretical) = Displacement(cc/rev) × Speed(r/min) ÷ 1000 (L/min)
-
Actual Output Flow Rate Q(Actual) = Q(Theoretical) × Volumetric Efficiency (Vane pump standard: 0.85 ~ 0.92)
-
Required Motor Power P(kW) = Working Pressure(MPa) × Actual Flow(L/min) ÷ 60 ÷ Overall Efficiency (0.75~0.85)
6. Suffix Code Definition for Full Series Pumps
-
Special Seal: M = Water-glycol medium seal; P = Fluorine rubber seal for phosphate ester medium
-
Port Orientation: A/AA/AB/AR stands for outlet port upward / right / left
-
Shaft Type: Standard key shaft as default; spline shaft for customized model
-
Version Code: 41/43/60 represent internal structure upgrade versions.
