PV2R1-25-L-RAA-43 Hydraulic Vane Oil Pump
Q1: What do the letters and numbers in the model PV2R1-25-L-RAA-43 stand for?
It is the specification code of a single-unit fixed-displacement vane pump in the PV2R series, with clear meanings for each part:
- PV2R1: Indicates the basic series of the pump, a Type 1 sub-series in the PV2R family, commonly used in medium and small displacement hydraulic systems.
- 25: Represents the pump displacement, 25CC/Rev, meaning the pump delivers 25 cubic centimeters of hydraulic oil per revolution.
- L: Denotes two key settings—counterclockwise rotation (viewed from the shaft end) and a specific oil outlet position configuration.
- RAA: An auxiliary code related to installation and interfaces, usually corresponding to standard flange mounting and conventional inlet/outlet position matching.
- 43: A manufacturer-defined suffix code, typically used to distinguish minor product specifications, production batches, or adapted specific working condition standards.
Q2: What are the core performance parameters of this hydraulic pump?
As a standard model in the PV2R series, its core parameters are suitable for general industrial scenarios:
- Rated displacement: 25CC/Rev, with output flow proportional to rotational speed.
- Maximum working pressure: Up to 175bar, and up to 210kgf/cm² (approximately 20.6MPa) for some adapted working conditions.
- 무게: About 12kg, facilitating equipment integration and installation.
- Equipped with special alloy bearings for strong axial load capacity and automatic clearance compensation, maintaining high volumetric efficiency under high pressure.
Q3: What structural and performance advantages does it have?
This model inherits the core advantages of the PV2R series, adapting to high-intensity industrial working conditions:
- Easy maintenance: The cartridge assembly is simple to disassemble and assemble, requiring no complex tools for later inspection and repair, reducing maintenance costs.
- Stable operation: Adopts a double-acting vane structure to optimize vane force, ensuring stable output under high pressure with low operating noise.
- Long service life: Special alloy bearings significantly improve axial load capacity, extending service life by 30% under high pressure compared to ordinary vane pumps.
- Flexible adaptation: Rotation direction can be switched flexibly, and inlet/outlet positions can be selected on demand to match the installation layout of different equipment.
Q4: In which fields is this hydraulic pump commonly used?
With balanced performance, its applications cover multiple industrial and mechanical fields:
- Rubber and plastic machinery: Driving hydraulic actuators of rubber vulcanizing machines and plastic injection molding machines.
- Machine tools: Providing power for hydraulic clamping and feed systems of lathes, milling machines, 등.
- General hydraulic units: Used in fixed hydraulic power stations to supply power for hydraulic circuits of small construction machinery and light industry machinery.
- Other fields: Also adaptable to auxiliary hydraulic systems of forging machinery and transportation machinery to control the smooth movement of components.
Q5: What are the characteristics of the pump’s material and core structure?
Material and structural design focus on durability and efficiency:
- The main body is made of cast iron, and key components such as vanes and bushings are made of alloy steel or copper alloy, balancing strength and wear resistance.
- The core structure includes floating pressure side plates that automatically compensate for axial clearance, avoiding leakage under high pressure and maintaining volumetric efficiency. The double-acting vane design ensures uniform force distribution, reducing pulsation and noise during operation.
Q6: Can this model replace other similar products?
Yes, it has strong interchangeability. This model can directly replace Yuken’s PV2R1 series products of the same specification, with consistent installation dimensions and interface specifications as the original factory. In addition, PV2R1-25 specification pumps produced by multiple domestic manufacturers can also be interchanged with this model, meeting users’ needs for cost control or emergency replacement.
Q7: What precautions should be taken when purchasing and using it?
Pay attention to adaptability and maintenance details to ensure stable operation:
- During model selection, confirm that the working pressure and rotational speed of the equipment’s hydraulic system are within the pump’s rated range to avoid overpressure operation.
- During installation, match the corresponding rotation direction and inlet/outlet positions to prevent pump damage caused by reverse connection.
- Use suitable hydraulic oil in daily use, replace the filter element regularly, and avoid impurities entering the pump body to wear vanes and side plates.
- This product usually comes with a 1-year warranty. Technical support via video is available after-sales. For faults, it is recommended to contact the manufacturer first for maintenance guidance.
