Specifications of YUKEN PV11R, PVL and PVR50 Vane Pumps

1. YUKEN PV11R Series Vane Pumps

The PV11R series is a new type of ultra-high pressure vane pump, which solves the problem of excessive wear of vanes and stators under high pressure through special lubrication methods and mechanical structures. It is widely used in various hydraulic systems requiring high pressure and stable performance.

1.1 Model Designation

Example: PV11R10-12-L-RAA-20

• PV11R: Series number
• 10/20: Nominal displacement series (PV11R10 and PV11R20)
• 12: Nominal displacement (cm³/rev)
• L: Foot mounting (F: Flange mounting)
• R: Clockwise rotation (viewed from the shaft end; counterclockwise is available on request)
• A: Discharge port position (upward, standard)
• A: Suction port position (standard)
• 20: Design number

1.2 Key Specifications

1.3 Additional Notes

• Hydraulic Fluid: Petroleum-based hydraulic oil (ISO VG32 or 46 is recommended); Phosphate ester fluid is available by adding “F-” before the model number (special fluororubber seal required).
• Typical Performance: Tested at viscosity 20 mm²/s (ISO VG32 equivalent) and oil temperature 50°C; Output flow and input power vary with shaft speed and operating pressure (see performance curves for details).
• Mounting: Foot mounting (L) and flange mounting (F) are available; Pipe flange components are not included and need to be ordered separately according to the model.

2. YUKEN PVL Series Vane Pumps

The PVL series single vane pumps are designed for small-sized machine tools that require relatively low pressure and small flow rates. They feature compact structure, stable operation and low noise, suitable for light-load hydraulic systems.

2.1 Model Designation

Example: PVL1-4-L-RA-K-31

• PVL1: Series number
• 4: Nominal displacement (cm³/rev)
• L: Foot mounting (F: Flange mounting)
• R: Clockwise rotation (viewed from the shaft end; counterclockwise is available on request)
• A: Discharge port position (upward, normal)
• K: Keyed shaft (V: Tang shaft)
• 31: Design number

2.2 Key Specifications

2.3 Additional Notes

• Hydraulic Fluid: Only petroleum-based hydraulic oil (R&O type or anti-wear type, equivalent to ISO VG32 or 46) is recommended; Maximum viscosity is restricted when starting the pump at low speed.
• Mounting: Foot mounting (L) and flange mounting (F) are available; Threaded connections are standard for ports.
• Shaft Type: Keyed shaft (K) and tang shaft (V) are optional; Design standards can be adjusted according to Japanese (JIS), European or North American standards on request.

3. YUKEN PVR50 Series Vane Pumps

The PVR50 series vane pumps are widely used as a hydraulic power source in various industrial fields. They combine stable performance, robust construction and a wide range of delivery rates, with low noise and low flow pulsation.

3.1 Model Designation

Example: F-PVR50-L-F-13-RAA-3180

• F: For phosphate ester type fluids (omit if not required)
• PVR50: Series number
• L: Foot mounting (F: Flange mounting)
• F: Flange pipe connection (T: Threaded connection; not available for 56 capacity)
• 13: Nominal delivery (cm³/rev)
• R: Clockwise rotation (L: Counterclockwise)
• A: Discharge port position (normal, upward)
• A: Suction port position
• 3180: Design number (30-39 are available, installation dimensions remain unchanged)

3.2 Key Specifications

3.3 Additional Notes

• Hydraulic Fluid: Suitable for various hydraulic fluids; Phosphate ester fluid is available by adding “F-” before the model number (special seals required, consult YUKEN for details).
• Typical Performance: Tested at viscosity 20 cst (ISO VG32, temperature 50°C); Output flow and input power vary with shaft speed and operating pressure (see performance curves for details).
• Applications: Widely used in light industry machinery (injection molding machines, blow molding machines, die-casting machines, shoe machines), forging machinery (pipe bending machines, hydraulic presses, bending machines), metallurgical machinery and port machinery.
• Shaft Type: Standard shaft is default; Special shaft is available for 51 and 56 capacity models on request.

General Notes

• All specifications are typical values; For detailed performance curves and installation dimensions, please refer to the official YUKEN product catalog or consult the manufacturer.
• The design number is subject to change, but the installation dimensions remain unchanged; For special requirements (such as counterclockwise rotation, special seals), please consult YUKEN before ordering.
• Regular maintenance (checking oil level, replacing oil filter and seals) is recommended to ensure the long-term stable operation of the pump.
