YUKEN PVL12 and PVL23 are high-quality fixed-displacement hydraulic vane pumps, belonging to YUKEN’s well-known PVL series of vane pumpssuperscript:1superscript:6. As single vane pumps, they are designed with a compact structure and reliable performance, suitable for a wide range of medium and low-pressure hydraulic systems, providing stable fluid power for various industrial machinery.

Designed primarily for general industrial hydraulic applications, the PVL12 and PVL23 hydraulic pumps excel in scenarios requiring stable flow output and low noise operation, such as small to medium-sized hydraulic machinery, automated equipment, and light-duty hydraulic systems. Their rational structural design ensures high operational efficiency and long service life, making them a cost-effective choice for industrial hydraulic applications.

1. PVL12 Hydraulic Pump

The PVL12 hydraulic pump is engineered for small-sized hydraulic systems with its compact volume and light weight, adapting to equipment with limited installation space. It maintains a maximum operating pressure of 16 MPa (160 bar) and a maximum rotational speed of 1800 r/min, ensuring stable and efficient operation under medium-pressure working conditions.

Key specifications of the PVL12 include a displacement range of 10–25 cm³/rev, with a net weight of approximately 18 kg. Its core advantages lie in low noise (≤68 dB), high volumetric efficiency (≥95%), and easy maintenance. The pump adopts a子母 vane structure, which effectively reduces wear and improves the overall stability and service life of the pump.

2. PVL23 Hydraulic Pump

The PVL23 hydraulic pump is tailored for medium-sized hydraulic systems, boasting a larger displacement range than the PVL12 to meet the demand for higher flow output. It features a maximum operating pressure of 16 MPa (160 bar) and a maximum rotational speed of 1800 r/min, adapting to continuous operation scenarios of medium-duty hydraulic machinery.

For the PVL23, the displacement range is 28–50 cm³/rev, and it weighs around 27 kg. Similar to the PVL12, it adopts a high-quality子母 vane design and precision machining technology, resulting in low flow pulsation (≤±4%) and stable pressure output. Its integrated oil distribution structure reduces internal leakage and improves energy utilization efficiency.
