AR Axial Piston Pumps

Product Overview

AR Axial Piston Pumps (YUKEN AR series) is a swashplate type variable displacement axial piston pump, designed for medium pressure compact hydraulic system. It converts rotary mechanical power into hydraulic energy, serving as the compact power source for small and medium industrial Machine. Famous for lightweight, small footprint and low noise, this pump adopts pressure compensator control, automatically adjusting output flow to stabilize system pressure. It is widely used in machine tools, plastic machinery and small hydraulic power units.

Technical Specifications

- Main models: AR16, AR22

- Displacement: AR16:15.8 cm³/rev; AR22:22.2 cm³/rev

- Nominal pressure: 160 bar

- Peak pressure: 210 bar

- Control type: Pressure compensator control (01 type)

- Speed range: 600 ~1800 rpm

- Mounting: Flange mounting; port options: axial port / side port

- Rotation direction: Standard clockwise (R), optional counter-clockwise (L)

- Weight: AR16 approx.9.8kg; AR22 approx.12.5kg

Working Principle

Driven by the motor, the shaft drives cylinder block and piston assembly to rotate. Pistons slide on the inclined swashplate and generate reciprocating axial movement to finish oil suction and oil discharge. When system pressure rises to the preset value, the pressure compensator acts to reduce swashplate tilt angle, lower pump displacement and cut flow, maintaining constant pressure for the hydraulic system. If system pressure drops, the swashplate angle increases automatically to recover output flow.

Key Features

1. Compact & lightweight design, smaller size and lighter weight compared with traditional A series piston pumps

2. Optimized swashplate bearing structure, low noise operation, 1~2dB quieter than old models

3. Built-in pressure compensator, stable pressure holding, energy saving when standby

4. Simple structure, easy installation and maintenance, can directly couple with hydraulic motor

5. Two port layout selections (axial / side port), flexible arrangement for limited-space Machine

6. High volumetric efficiency, stable performance for continuous medium-pressure working cycle

Application

- Machine tools: CNC lathe, machining center, bending machine

- Plastic machinery: small injection molding machine

- Industrial equipment: small hydraulic power pack, press, die casting auxiliary equipment

- Other compact hydraulic system requiring stable medium pressure power supply
