Product details
I. Product Overview
The Daikin V8A1RX-20 is a swashplate-type axial piston pump designed with a closed-circuit configuration, optimized for medium-to-high-pressure hydraulic systems. It achieves continuous fluid delivery through the reciprocating motion of multiple precision pistons, offering adjustable flow rates and rapid response characteristics. This makes it ideal for applications demanding high dynamic performance and energy efficiency.

V. Model Breakdown (Example: V8A1RX-20)
• V: Indicates the V series.
• 8: Displacement code (other options include 15, 23, 38, 50, 70, etc.).
• A: Control mode (e.g., A = pressure compensation; C = combination control; D = composite pressure control; SA = power matching control).
• 1: Pressure regulation range (e.g., 1 = 1.5–7 MPa; 2 = 1.5–14 MPa; 3 = 1.5–21 MPa; 4 = 1.5–25 MPa).
• R: Rotation direction (R = clockwise; L = counterclockwise).
• X: Port orientation (X = side ports; no marking = ports on both sides).
• 20: Design number.
