YUKEN PVR12 and PVR13 are high-reliability fixed-displacement hydraulic vane pumps, belonging to YUKEN’s practical PVR series. As single vane pumps, they are specially designed to provide stable and efficient fluid power for medium-pressure hydraulic systems, featuring a compact structure, low noise and easy maintenance, which makes them widely applicable in various general industrial machinery and hydraulic equipment.

Designed primarily for general industrial and light to medium-duty hydraulic applications, the YUKEN PVR12 and PVR13 hydraulic pumps excel in scenarios requiring stable flow output, low energy consumption and continuous operation, such as small to medium-sized hydraulic presses, automated equipment, plastic machinery and light-duty processing equipment. Their optimized structural design and precision manufacturing ensure excellent operational stability and long service life, making them a cost-effective choice for industrial hydraulic systems.

1. Core Specifications & Technical Parameters

Both PVR12 and PVR13 adopt a fixed displacement design, with their model numbers reflecting their respective displacement ranges, which are the core parameters determining their flow output capacity. Both pumps maintain a maximum operating pressure of 16 MPa (160 bar), equivalent to 2320 PSI, and a maximum rotational speed of 1800 r/min, ensuring stable and efficient operation under medium-pressure working conditions.

Key technical specifications differ slightly between the two models: the PVR12 has a displacement range of 11–24 cm³/rev, a net weight of approximately 17 kg, a volumetric efficiency of ≥95%, and a noise level of ≤68 dB; the PVR13 features a larger displacement range of 25–48 cm³/rev, a net weight of about 26 kg, a volumetric efficiency of ≥96%, and a noise level of ≤70 dB. Both pumps adopt precision-machined stator curves and high-quality vane designs, which effectively reduce flow pulsation (≤±4%) and internal leakage, ensuring consistent pressure and flow output during long-term operation.

2. Structural Features & Core Advantages

YUKEN PVR12 and PVR13 integrate mature hydraulic technology and precision manufacturing processes, with structural features that prioritize stability, practicality and easy maintenance. Both adopt an integrated oil distribution plate design, which optimizes oil flow paths, reduces pressure loss and improves energy utilization efficiency. The pumps also use a子母 vane structure, which effectively reduces vane wear and enhances the overall stability and service life of the pump.

Their core advantages are reflected in multiple aspects: first, reliable medium-pressure performance, which can stably operate under the maximum pressure of 16 MPa, adapting to the working requirements of light to medium-duty hydraulic systems; second, low noise and low vibration, thanks to the optimized stator curve and balanced vane structure, which reduces the impact of fluid flow on the pump body and ensures a quiet working environment; third, easy maintenance, with a simple internal structure that allows quick disassembly and replacement of wearing parts, reducing downtime and maintenance costs; fourth, strong pollution resistance, which can adapt to general industrial oil cleanliness requirements and maintain stable operation in harsh working environments.

3. Application Scenarios

Due to their excellent performance, stable operation and cost-effectiveness, YUKEN PVR12 and PVR13 hydraulic pumps are widely used in various industrial fields that require medium-pressure hydraulic power. Typical application scenarios include small to medium-sized hydraulic presses (100–300 tons), injection molding machines, metal processing machinery, packaging machinery, automated production lines and engineering machinery accessories that require stable pressure holding and continuous fluid supply.

Specifically, the PVR12, with its smaller displacement and lighter weight, is more suitable for small-sized hydraulic equipment and automated systems with limited installation space; the PVR13, with its larger displacement, is better adapted to medium-sized hydraulic machinery that requires higher flow output, such as medium-sized injection molding machines and metal processing equipment, providing reliable hydraulic support for the stable operation of various equipment.
