YUKEN PV2R Series Double Vane Pump: Specifications & Introduction

1. Model Designation Explanation

• PV2R: Series identifier for double vane pumps.
• 13: Series number, indicating the basic structure and size (optional series: 12, 13, 23, 33, 14, 24, 34).
• 6: Nominal displacement of the small-volume pump (unit: ml/rev), with optional ranges varying by series.
• 40: Nominal displacement of the large-volume pump (unit: ml/rev), with different options for each series.
• A: Discharge port position of the small-volume pump (viewed from the shaft end); default is upward (A), other options include left 45° upward (E) etc.
• F: Discharge port position of the large-volume pump (viewed from the shaft end); common options are upward (A) and right 45° upward (F).
• 76: Design standard number, matching different installation and structural requirements.
• A: Suction port position (viewed from the shaft end); default is upward (A), with alternatives like downward (B) or left (L).
• R: Rotation direction; clockwise (R) is standard, counterclockwise (L) is available on request.
• L: Mounting type; foot mounting (L) or flange mounting (F) are optional.
• A: Seal type; standard seal for mineral oil, “A” indicates special seals for phosphate ester type fluids (omitted if not required).

3. Performance & Structural Features

• Integrated Compact Design: Two pumps share one housing and shaft, reducing installation space and simplifying pipeline layout.
• Stable Operation: Adopts double-acting vane structure, with centrifugal force and hydraulic pressure ensuring tight contact between vanes and stator, minimizing flow pulsation.
• Energy Efficiency: Fixed displacement design with high volumetric efficiency, reducing power loss and oil temperature rise, suitable for energy-saving hydraulic systems.
• Durable Construction: Made of high-strength cast iron, with precision-machined components and high-quality seals, extending service life in harsh working conditions.
• Customizable Configurations: Optional rotation direction, port positions, and seals to meet specific application needs; pipe flange kits are available for easy installation.
