YUKEN Double hydraulic pump PV2R23、PV2R24

YUKEN PV2R23 and PV2R24 are high-performance double fixed-displacement hydraulic vane pumps, which are part of YUKEN’s renowned PV2R series. These double pumps are constructed by integrating two single PV2R series pumps in tandem within a single housing, driven by a common shaft, featuring a single suction port and two discharge ports that allow the output flow to be supplied to separate hydraulic circuits independentlysuperscript:3.

Designed primarily for hydraulic press applications, the PV2R23 and PV2R24 double pumps excel in scenarios requiring dual flow output, such as rapid advance/retreat (using large flow) and pressing/holding pressure (using small flow), which can achieve energy savings of 30% to 50% compared with single pumps, making them the preferred choice for various hydraulic machinery.

1. PV2R23 Double Hydraulic Pump

The PV2R23 double pump is engineered for large hydraulic presses (500–1000 tons) with its optimized displacement combination and stable performance. It maintains a maximum operating pressure of 21 MPa (210 bar) and a maximum rotational speed of 1800 r/min, ensuring reliable operation under high-pressure working conditionssuperscript:2.

Key specifications of the PV2R23 include a displacement combination range of 41–65 cm³/rev (small volume pump) and 52–116 cm³/rev (large volume pump), with a net weight of approximately 51 kg. Its core advantages lie in low noise (≤72 dB), high volumetric efficiency (≥97%), and strong pollution resistance, requiring only NAS 10-grade oil cleanliness for stable operationsuperscript:2>.

2. PV2R24 Double Hydraulic Pump

The PV2R24 double pump is tailored for extra-large hydraulic presses (1000–2000 tons), boasting a larger displacement range to meet the demand for high flow and high pressure. It also features a maximum operating pressure of 21 MPa (210 bar) and a maximum rotational speed of 1800 r/min, adapting to heavy-duty continuous operation scenariossuperscript:2.

For the PV2R24, the displacement combination ranges from 26–47 cm³/rev (small volume pump) to 136–237 cm³/rev (large volume pump), and it weighs around 78 kg. Similar to the PV2R23, it adopts a high-order equation stator curve, resulting in a flow pulsation of ≤±3% and high pressure holding precision, while its integrated chuck assembly enables easy maintenance by simply replacing the chucksuperscript:2>.

Common Core Advantages

• Dual independent oil supply: The double-pump structure realizes dual-circuit operation of rapid movement and pressure holding, greatly improving work efficiency and energy utilization.
• Compact design: Integrating two pumps into one housing saves installation space and is suitable for the integrated design of hydraulic presses.
• Stable and durable: High pressure resistance, low heat generation, and strong anti-pollution ability ensure long-term continuous operation in harsh industrial environments.
• Wide application: Widely used in hydraulic presses, bending machines, punching machines, and straightening machines, meeting the core working conditions of high pressure, low pulsation, and stable pressure holdingsuperscript:5>.
