YUKEN PV2R1-12 and PV2R1-17 are high-performance single-stage vane pumps independently developed by Yuken Industry Co., Ltd., a well-known Japanese hydraulic equipment manufacturer. As core products of the PV2R1 series, these two pumps inherit the series’ advantages of high pressure resistance, low noise, high reliability and stable performance, and are widely used in various hydraulic systems that require precise and efficient power supply, playing an irreplaceable role in precision machining, light and heavy industry fields.

Product Core Parameters

Both PV2R1-12 and PV2R1-17 belong to the same series, so they share most structural and performance characteristics, but differ mainly in geometric displacement, which leads to slight differences in output flow and applicable load scenarios. The specific parameters are as follows:

• YUKEN PV2R1-12 Vane Pump: The geometric displacement is 12.2 cm³/rev (0.744 cu.in./rev). The maximum operating pressure can reach 21 MPa (3050 psi) when using anti-wear petroleum base oils, ensuring stable oil supply under medium and low load conditions. The shaft speed ranges from 600 r/min to 1800 r/min (recommended speed is 1200 r/min), and the volumetric efficiency is not less than 92%, which effectively reduces energy loss and improves the overall efficiency of the hydraulic system.
• YUKEN PV2R1-17 Vane Pump: Its geometric displacement is 16.6 cm³/rev (1.013 cu.in./rev), slightly larger than that of the PV2R1-12. It also has a maximum operating pressure of 21 MPa (3050 psi) for anti-wear petroleum base oils, with a shaft speed range of 600-1800 r/min. The higher displacement enables it to provide larger output flow, making it more suitable for hydraulic systems that require higher flow demand under the same pressure conditions.

Both pumps are suitable for a variety of hydraulic media, including anti-wear petroleum base oils, R&O type oils, water glycols and synthetic fluids, with a medium temperature range of -10°C to 80°C, adapting to different working environment requirements.

Structural Features & Core Advantages

The two vane pumps adopt advanced structural design and high-quality materials, integrating performance and durability, and their core advantages are reflected in the following aspects:

1. Low Noise Operation: Adopting arc vane structure and high-order equation stator curve design, the pressure and flow pulsation are effectively optimized, and the operating noise is controlled below 70 dB(A), which meets the quiet environment requirements of precision equipment such as machine tools.
2. High Pressure & High Efficiency: With a maximum operating pressure of 21 MPa, they can adapt to high-load working scenarios. The volumetric efficiency of not less than 92% ensures stable oil supply, reduces energy loss, and improves the energy-saving performance of the entire hydraulic system.
3. Long Service Life & High Reliability: The stator and vanes are treated with special surface technology, which increases their service life by 30% and reduces maintenance frequency. The aluminum alloy material used in the pump body has explosion-proof performance, enabling the pump to work stably in complex working conditions.
4. Easy Maintenance: The integrated driving components of the pumps are configured as a kit and can be supplied as a cartridge assembly, which facilitates the quick replacement of driving parts, shortens maintenance time and reduces maintenance costs.
5. Compact Structure: The overall design is compact and lightweight, which is convenient for installation in limited space, and the flange installation method is optional, further improving the flexibility of equipment matching.

Application Scenarios

Due to their excellent performance and flexible parameter matching, YUKEN PV2R1-12 and PV2R1-17 vane pumps are widely used in various fields that require stable hydraulic power supply, mainly including:

• Precision Machining Equipment: They are widely used in CNC machine tools and grinders. For example, they provide stable hydraulic power for the spindle and feed system of CNC machine tools to ensure the accuracy of milling, drilling and other processing; in grinders, they drive the砂轮 feed and workpiece clamping to ensure the surface processing accuracy of workpieces.
• Light Industry Machinery: Suitable for injection molding machines, die-casting machines, bending machines, shearing machines and other equipment, providing stable power for the hydraulic system of the equipment to ensure the smooth progress of production operations.
• Other Industrial Fields: It can also be applied to hydraulic systems of leather machinery, forging machinery and other equipment, adapting to different working conditions and load requirements, and providing reliable hydraulic support for industrial production.

Summary

YUKEN PV2R1-12 and PV2R1-17 vane pumps are high-quality hydraulic power components that combine high performance, reliability and economy. The PV2R1-12 is suitable for hydraulic systems with small flow demand and light to medium load, while the PV2R1-17 is more suitable for systems with larger flow demand under the same pressure. Both pumps have the advantages of low noise, high efficiency, long service life and easy maintenance, which can effectively improve the stability and efficiency of hydraulic systems, and are the preferred products for hydraulic system upgrading and matching in various industries.
