A10-F-R-01-C-12 YUKEN Variable Piston Pump 16 MPa

Product Overview

The YUKEN A Series is a family of swash-plate variable displacement piston pumps designed for industrial hydraulic systems. YUKEN describes its A Series as low-noise, high-efficiency variable piston pumps and offers multiple control configurations, including pressure-compensator and proportional control.

The models in the original title should be standardized as:

• A10-F-R-01-C-12, corresponding to YUKEN A10-FR01C-12
• A10-FR01H-13, which is the closest officially documented model to the supplied A10-FRD1H-13
• A16-F-R-01-H-K-32
• A16-F-R-01-H-S-K-32

The YUKEN A16 model code identifies:

• F = flange mounting
• R = clockwise rotation
• 01 = pressure-compensator control
• H = 1.2–21 MPa pressure-adjustment range
• S = side ports
• K = parallel-key shaft
• 32 = design number.

For replacement applications, our engineering process matches the complete model code, mechanical interfaces, port orientation and controller characteristics, followed by 100% simulated working-condition testing.

Key Technical Advantages

1. Pressure-Compensated Variable Displacement

The 01 control is a pressure compensator. As system pressure approaches the compensator setting, the pump reduces effective displacement, preventing unnecessary full-flow operation at high pressure.

2. Low Noise and High Efficiency

YUKEN identifies low noise and high efficiency as key characteristics of its A Series swash-plate piston pumps.

3. Compact A10 Configuration

The A10 provides 10.0 cm³/rev displacement, 16 MPa rated pressure, 21 MPa maximum/intermittent pressure and a 600–1,800 rpm speed range, making it suitable for compact industrial hydraulic systems.

4. Higher-Flow A16 Configuration

A16 increases geometric displacement to 15.8 cm³/rev while retaining a 16 MPa rated pressure and 21 MPa maximum/intermittent pressure.

5. Multiple Pressure-Adjustment Ranges

The complete model code is critical because the adjustment range changes with the pressure code:

• A10 C: 2.0–16 MPa
• A10 H: 2.0–21 MPa
• A16 H: 1.2–21 MPa.

6. Axial-Port and Side-Port Versions

For A16:

A16-F-R-01-H-K-32
→ axial-port configuration

A16-F-R-01-H-S-K-32
→ side-port configuration

This distinction is important for direct replacement because port orientation affects hydraulic piping and installation space.

7. Precision Axial-Piston Rotating Group

Long-term pump efficiency and service life depend on close-tolerance interfaces between the cylinder block, pistons, slippers, swash plate, valve plate, bearings and seals.

For replacement manufacturing, matching external dimensions alone is therefore insufficient. Hydraulic performance must be verified under representative load conditions.

8. Controlled Shaft Alignment Requirements

YUKEN’s A16 installation guidance specifies flexible coupling and limits shaft misalignment to 0.1 mm TIR with angular error within 0.2°.

Application Areas

Typical applications for YUKEN A10 and A16 A Series pumps include:

• Hydraulic power units
• Machine tools
• Injection molding machinery
• Hydraulic presses
• Metal-forming equipment
• Industrial clamping systems
• Automation hydraulic circuits
• Compact hydraulic power packs
• Multi-actuator open-circuit hydraulic systems

The final application should always be checked against displacement, operating pressure, motor speed, pressure-compensator setting, port configuration and shaft interface.

Expert Maintenance Tips

1. Fill the Housing Before Start-Up

YUKEN installation guidance requires filling the pump housing with hydraulic oil before initial operation. Start-up should be performed with the delivery line unloaded while confirming proper oil intake.

2. Remove Entrained Air

Air inside the pump or hydraulic lines can cause abnormal vibration, noise and unstable pressure/flow. YUKEN specifically recommends thorough air bleeding during initial commissioning and after long periods of shutdown.

3. Maintain Shaft Alignment

For A16 installations:

• Shaft misalignment: ≤ 0.1 mm TIR
• Angular error: ≤ 0.2°
• Use a flexible coupling
• Do not impose bending or thrust loads on the pump shaft.

4. Protect the Suction Circuit

YUKEN specifies an inlet pressure range around −16.7 kPa to +50 kPa for the A16 configuration. Reservoir level, suction-line restriction and filter pressure loss should therefore be checked together.

5. Maintain Hydraulic Cleanliness

The A16 installation instructions specify cleanliness of ISO 4406 21/19/15 or NAS Class 10 or better and recommend approximately 100 μm / 150-mesh suction filtration and 10 μm or finer delivery/return filtration.

6. Maintain Proper Oil Viscosity and Temperature

For A16, YUKEN specifies:

• Viscosity: 20–400 mm²/s
• Recommended viscosity grade: ISO VG 32–46
• Temperature: 0–60°C.

7. Verify Port Orientation During Replacement

Do not treat the following as mechanically identical:

• A16-F-R-01-H-K-32: axial ports
• A16-F-R-01-H-S-K-32: side ports

The S code directly affects piping orientation and installation geometry.

8. Separate Rated Pressure From the Adjustment Range

For A16-H, the pressure-adjustment range reaches 21 MPa, while the rated pressure is 16 MPa. These are not interchangeable specifications and should remain separately identified in an engineering datasheet.
