Description
1. Product Overview
1.1 Single Vane Pumps
The PV2R series single vane pumps are high-pressure, high-performance hydraulic components specifically developed for low-noise operation. They cover a wide range of geometric displacements from 5.8 cm³/rev to 237.0 cm³/rev, making them suitable for various applications such as injection moulding machines. The integral driving parts are integrated into a cartridge kit, enabling easy replacement and maintenance without disassembling the entire pump.
1.2 Double Vane Pumps
The PV2R series double vane pumps consist of two single PV2R series pumps combined in tandem within a single housing, driven by a common shaft. They are equipped with one suction port and two discharge ports, allowing the output flow to be supplied to separate hydraulic circuits simultaneously, thus optimizing system efficiency and integration.

3.2 Fluid Compatibility
-
Petroleum-based oils: Anti-wear type, R&O type
-
Water-containing fluids: Water glycols, water-in-oil emulsions
-
Synthetic fluids: Phosphate esters (requires F- prefix for special seals)
3.3 Key Notes on Parameters
-
For pressure above 16 MPa (160 kgf/cm²), the shaft speed must be raised over 1450 r/min.
-
When using phosphate ester or water-containing fluids, the maximum speed is limited to 1200 r/min.
-
For PV2R3-116 at speeds above 1700 r/min, the suction pressure is limited to 0 MPa.
-
For PV2R4-237 at speeds above 1700 r/min, the suction pressure is limited to 0.013 MPa (0.13 kgf/cm²).
4. Installation & Accessories
4.1 Mounting Types
Two mounting options are available: foot mounting (code L) and flange mounting (code F), compatible with standard installation dimensions for industrial hydraulic systems.
4.2 Pipe Flange Kits
Pipe flange kits are sold separately. Select the appropriate kit based on the pump model and connection type (threaded, socket welding, butt welding).

Note: For socket welding flanges, the operating pressure must be reduced due to flange strength limitations. Confirm the max. allowable pressure before use.
5. General Precautions
-
Anti-clockwise rotation pumps are available on request. Contact YUKEN for detailed specifications.
-
The maximum viscosity is limited when starting at low speeds. Refer to the “Hydraulic Fluids” section in EIC-N-1001 for details.
-
Use fluororubber seals (indicated by F- prefix) when handling phosphate ester fluids to ensure compatibility and durability.
-
Typical pump characteristics are tested at a viscosity of 20 mm²/s (100 SSU) with ISO VG 32 oil at 50°C (122°F).
6. Design Standards
Compliant with Japanese Industrial Standard (JIS), European design standards, and North American design standards, ensuring global applicability and interchangeability.
