YUKEN Double hydraulic pump PV2R23、PV2R24
YUKEN Double Vane Pump PV2R23 and PV2R24 Series: Models & Parameters
1. Overview
YUKEN PV2R23 and PV2R24 series double vane pumps are composed of two single PV2R series vane pumps integrated in a single housing, driven by a common shaft. They are designed with a single suction port and two discharge ports, which can supply output flow to separate hydraulic circuits respectively. These pumps feature high operating pressure, low noise, and easy maintenance, widely applicable to various hydraulic systems such as injection molding machines and industrial machinery.
2. Model Designation
The model designation of YUKEN PV2R23 and PV2R24 series double vane pumps follows a unified standard, and the specific meaning is as follows (taking a typical model as an example):
Example: PV2R23-* -* -F-RAAA-31/3190

4. Additional Technical Parameters
4.1 Suction Pressure Requirement
The minimum suction pressure of the pump is related to the shaft speed and displacement. For PV2R23 series pumps with a large-volume pump displacement of 116 cm³/rev, the minimum suction pressure is -20 kPa when the shaft speed is less than 1700 r/min, and 0 kPa when the shaft speed is 1700 – 1800 r/min. For PV2R23 series pumps with a large-volume pump displacement of 76 or 94 cm³/rev, the minimum suction pressure is -20 kPa when the shaft speed is less than 1700 r/min, and -6.7 kPa when the shaft speed is 1700 – 1800 r/min.
4.2 Hydraulic Fluid Requirements
-
Recommended hydraulic fluid: Petroleum-based oils, water-containing fluids, or phosphate esters (special seals required for phosphate esters).
-
Maximum viscosity: 200 mm²/s (910 SSU) at a shaft speed of 950 r/min; 100 mm²/s (455 SSU) at a shaft speed of 600 r/min.
4.3 Pipe Connection Specifications
The pipe connection types for PV2R23 series include RC threaded connection (Type A), socket welding (Type B), and butt welding (Type C). The specific connection specifications are as follows:
-
Suction port: F5-24-A/B-10
-
Large-volume pump discharge port: F5-10-*-10
-
Small-volume pump discharge port: F5-06-*-10
5. Product Features
-
High Performance: Maximum operating pressure up to 210 bar, capable of meeting the requirements of high-pressure hydraulic systems.
-
Low Noise: Optimized structural design ensures low noise operation, suitable for noise-sensitive working environments.
-
Easy Maintenance: The integral driving parts are combined into a cartridge kit, which can be easily replaced when maintenance is needed.
-
Versatile Application: With a wide range of displacements, it can be applied to various hydraulic systems such as injection molding machines, machine tools, and engineering machinery.
6. Notes
-
The parameters in this document are standard values. For special working conditions (such as extreme temperature, special hydraulic fluid), please consult YUKEN for customized solutions.
-
When using phosphate esters as hydraulic fluid, a prefix “F-” must be added to the model number to indicate the use of special fluororubber seals.
-
The pump should be operated within the specified shaft speed and pressure range to avoid damage to the pump body and accessories.
