Detailed specifications of YUKEN PV2R series single vane pump
1. The range of core specifications and parameters
YUKEN PV2R series single vane pumps cover a displacement of 6.1 mL/rev to 237 mL/rev, forming a product matrix suitable for all scenarios of low, medium and high pressure.Typical model parameters are as follows：
Model classification Displacement range (mL/rev) Maximum pressure (MPa) Speed range (rpm) Weight range (kg)
PV2R1 series   6.1-23.0    21 (some models 16)     600 – 1800     8 – 11.2
PV2R2 series   25.4-74.5     21 (some models 16)     600 – 1800     15.5 – 19.8
PV2R3 series   51.5-153.0     21 (some models 16)    600 – 1800     30.9 – 40.9
PV2R4 series   125.0-237.0     17 (special model)      600 – 1800     68.5 – 93.5
Key note：
Pressure level: The maximum pressure of the standard model is 21 MPa, and the maximum pressure of some models (such as the PV2R4A series) is 17 MPa due to design optimization.
Speed matching: The speed range of all models is 600-1800 rpm, and it is necessary to ensure that it matches the speed of the drive motor.
Weight difference: The weight increases significantly with the increase of displacement, and the weight of the PV2R4 series base-mounted type can reach 93.5 kg.
2. Model naming rules and extensions
YUKEN PV2R series models adopt a standardized naming system, taking PV2R1-23-F-RAA-43 as an example：
PV2R1: Series number, indicating a single vane pump.
23: Nominal displacement code (unit: mL/rev).
F: Installation type (F is flange installation, L is base installation).
R: Direction of rotation (R is clockwise, L is counterclockwise).
A: The position of the output port (A is above, B is below, R is on the right, and L is on the left).
43: Design number, distinguish between different design versions.
Extended model example：
PV2R1-19-L-RAA-41: Displacement 19 mL/rev, base installation, rotating clockwise, above the output port.
PV2R3-76-F-RAAA-31: Displacement 76 mL/rev, flange installation, clockwise rotation, above the output port, design number 31.
3. Core performance characteristics
High-voltage and efficient design
The high-order equation curve stator and arc-shaped blade are used to reduce pressure and flow pulsation, and the life of the stator and blade is increased by more than 30%.
Some models (such as PV2R1-44FX) support extreme pressure of 350 bar, which is suitable for high-pressure scenarios such as injection molding machines and die-casting machines.
Wear resistance and long life
The surface of the key components (stator, blade) is treated with manganese phosphate film, and the life of the shaft seal group is up to 8,000 hours, and the life of the distribution disc is up to 12,000 hours.
High-quality materials (such as stainless steel and special alloys) are suitable for harsh working conditions (such as ship steering gear systems).
Low noise and energy saving
The volumetric efficiency is up to 92%, and the mechanical efficiency is optimized to reduce the driving power requirement and reduce heat generation.
The noise reduction design makes the operating noise lower than industry standards and is suitable for indoor machinery (such as CNC machine tools).
4. typical application scenarios
Industrial machinery field
Injection molding machine: PV2R1-19/23 provides stable high pressure for the mold closing unit and is suitable for small and medium-sized to large-scale systems.
Metal cutting machine tools: drive hydraulic chucks, sliding tables and other actuators to ensure high-precision machining.
Construction machinery field
Concrete conveying pump: provides continuous high pressure to ensure smooth conveying.
Crane: drive the luffing and rotating mechanism to achieve precise hoisting of heavy objects.
Shipbuilding industry
Servo system: provides stable hydraulic power to ensure the accuracy of heading control.
Windlass: Maintain sufficient tension in harsh sea conditions.
5. Selection suggestions
Traffic demand matching
Small system (flow rate ≤10 L/min): choose PV2R1-6/8/10.
Medium-sized system (flow rate 10-50 L/min): choose PV2R1-14/17/19/23 or PV2R2-26/33.
Large-scale system (flow rate>50 L/min): choose PV2R3-52/76/94 or PV2R4-136/153.
Pressure level confirmation
Confirm the highest pressure of the system, and give priority to pumps with sufficient pressure resistance (such as PV2R1-44FX for high pressure conditions).
Installation method selection
Flange installation (F) saves space and is suitable for compact equipment; base installation (L) has higher stability and is suitable for heavy equipment.
Cost optimization
Single pump system: PV2R1 series has a 30% lower maintenance cost, which is suitable for budget-sensitive projects.
Dual pump system: If complex hydraulic action is required, PV2R12 dual pumps (such as PV2R12-19/23) can be considered to save space and cost.
