YUKEN A16-F-R Piston Pump

Overview

The YUKEN A16-F-R is a flagship small-displacement model in the A Series variable piston pump family, specifically engineered for medium and small-sized industrial equipment requiring precise flow control and compact installation. Leveraging YUKEN’s 60+ years of hydraulic engineering expertise, this pump integrates flange-mounted design, clockwise rotation, and high-efficiency variable displacement technology to deliver reliable fluid power solutions for light industrial and automated production scenarios. Its optimized compact structure and low-noise performance make it an ideal choice for space-constrained machinery.

Core Technical Specifications

1. Displacement & Flow Performance

• Displacement: 16 cm³/rev (optimized for medium-flow precision applications)
• Rated Flow: 28.8 L/min (at 1800 rpm, rated pressure)
• Maximum Flow: 57.6 L/min (at 3600 rpm, peak operating speed)
• Flow Adjustment Range: 0～57.6 L/min (stepless regulation via swashplate angle control for on-demand oil supply)

2. Pressure & Speed Capabilities

• Maximum Working Pressure: Up to 21 MPa (varies by pressure range code: B=7 MPa / C=16 MPa / H=21 MPa)
• Adjustable Pressure Range: 1.2～21 MPa (model-dependent, precise matching for light to medium load cycles)
• Rated Speed: 1800 rpm
• Operating Speed Range: 600～3600 rpm (supports rapid actuation and low-speed pressure holding)
• Overload Capacity: Withstands 110% of maximum pressure for 3-minute cycles (enhanced structural integrity for intermittent heavy loads)

3. Efficiency & Energy Saving

• Volumetric Efficiency: ≥98% (tested at 16 MPa, 1800 rpm)
• Total Efficiency: ≥90% (15%～20% energy savings compared to conventional fixed-displacement pumps)
• Variable Displacement Mechanism: Adaptive swashplate design eliminates throttling losses, reducing power consumption in partial-load operations.

4. Noise & Temperature Control

• Low Noise Level: ≤57.3 dB(A) (at 1800 rpm, rated pressure) – industry-leading for small-displacement pumps
• Heat Generation: Oil temperature rise ≤35℃ under continuous operation (25% lower than standard small pumps), minimizing cooling system requirements.

Control Modes & Adaptability

1. Control Options

• Pressure Compensation Control (Type 01): Standard configuration with external pilot pressure signal (0.3～3.5 MPa) for stepless pressure adjustment, response time ≤0.4 seconds
• Electromagnetic Dual-Pressure Control (Optional Type 02): DC24V signal-driven high-low pressure switching (PL/PH) for automated small-scale production lines
• Standard Model Configuration: A16-F-R-01-B-K-60 / A16-F-R-01-C-K-60 (flange mounting, clockwise rotation, pressure compensation control, flat key shaft extension)

2. Installation Flexibility

• Mounting Type: Flange (F) installation as standard (optional base (L) mounting available)
• Rotation Direction: Clockwise (R) rotation (standard); counterclockwise (L) rotation available on request
• Port Position: Side (S) interface as standard for convenient pipeline layout
• Shaft Extension: Flat key (K) design ensures stable power transmission in medium-torque applications
• Dimensions: Compact footprint (compatible with A Series mounting standards) for space-constrained equipment.
