The double vane pumps are compose with two single PV2R series pumps, which were driving by one shaft and were assembled in parallel in one pump casing with one common inlet port and two outlet ports that conecting to two individual oil circuits.
A variety of flows can be obtained by different combination of two pumps. The power of double vane pumps is the power sum of two single vane pumps.

PV2R Series Duplex Vane Pump: Detailed Overview
ThePV2R Series Duplex Vane Pumpis a specialized hydraulic pump designed for applications requiringtwo independent flow circuitsin a single, compact unit. Below is a structured breakdown of its key features, applications, and advantages:
------
1. Key Features
• Dual-Pump Design (Duplex):
• Integratestwo independent vane pumpsinto a single housing.
• Each pump can operate at different pressures/flows (e.g., one for high-pressure circuits, another for low-pressure auxiliary functions).
• Fixed Displacement:
• Output flow is determined by displacement and rotational speed (non-adjustable during operation).
• Compact & Efficient:
• Shared shaft/housing reduces space requirements and simplifies piping.
• Low noise operation (vane pumps are quieter than gear pumps).
• Modular Configuration:
• Available in different displacement combinations (e.g., one pump at 16 cc/rev, another at 8 cc/rev).
• Optional priority flow valves for load-sensing applications.

2. Technical Specifications (Example: Yuken PV2R Series)
(Note: Specifics may vary by manufacturer; below is a typical range)
【表格】
Parameter Range
Displacement per Pump 8–146 cc/rev (varies by model)
Max. Operating Pressure 175–210 bar (2,538–3,046 psi)
Max. Speed 1,800–2,500 RPM
Port Size G1/2" to G1" (metric threads)
Mounting Flange, foot, or cartridge style
------
3. Applications
ThePV2R Duplex Vane Pumpis ideal for:
• Machine Tools:
• One pump for main hydraulic circuits (e.g., clamping, sliding tables).
• Another for lubrication or cooling systems.
• Plastic Injection Molding:
• Separate pumps for injection and clamping forces.
• Mobile Equipment:
• One pump for steering, another for auxiliary functions (e.g., lift arms).
• Test Stands & Presses:
• Independent control of multiple actuators.
------
4. Advantages Over Single Pumps
• Space-Saving: Two pumps in one housing reduce footprint.
• Cost-Effective: Lower piping and installation costs vs. two standalone pumps.
• Simplified Control: Shared drive reduces complexity in hydraulic circuits.
• Energy Efficiency: Independent pumps allow optimized flow for different loads.
------
5. Limitations
• Fixed Displacement: Flow cannot be adjusted dynamically (unlike variable displacement pumps).
• Pressure Limits: Lower max. pressure compared to piston pumps (typically up to 210 bar).
• Sensitivity to Contamination: Vane pumps require clean hydraulic fluid to prevent wear.
