PV2R12 Duplex Vane Pump Specifications
I. Core Performance Parameters
Displacement
Single Pump Displacement: Typically 50cc/rev (12cc/rev for some models, subject to confirmation based on specific model).
Dual Pump Displacement: When the two pumps operate in combination, the displacement is double that of a single pump, i.e., 100cc/rev (or adjusted depending on model).
Optional Displacement Range: The PV2R12 series offers single pump displacements from 6cc/rev to 237cc/rev, and dual pumps up to 362cc/rev.
Pressure Range
Rated Pressure: 12MPa (35MPa for some models, subject to design confirmation).
Maximum Pressure: Up to 350bar (approximately 35MPa), with some models offering maximum pressures of 41.4MPa or 18MPa (selectable based on application requirements).
Pressure Compatibility: Suitable for hydraulic systems requiring high-pressure output, such as injection molding machines and die-casting machines. Speed Range
Maximum speed: 3000 rpm (actual speed may vary due to factors such as the motor and hydraulic system).
Used speed range: 500-1800 rpm (depending on system requirements).
II. Structure and Drive Parameters
Drive Mode
Standard configuration: Electric motor drive (internal combustion engine drive option available upon request).
Rotation Direction: Clockwise (F) or Counterclockwise (L), identified by the model suffix.
Mounting and Connection
Mounting method: Flange (F) or foot-mounted (L), supporting various oil inlet and outlet positions. Connection Dimensions: Pipe sizes (PT) vary depending on the model, offering options such as 1/2″, 3/4″, and 1″.
External Dimensions: Typical installation dimensions are 300mm × 300mm × 300mm (depending on the model).
III. Environmental and Media Parameters
Applicable Media
Hydraulic Fluid: Mineral or synthetic oil (add “F” to the model number when using phosphate ester hydraulic fluid).
Lubricant: Suitable for hydraulic systems requiring lubrication.
Operating Environment
Temperature Range: -20°C to +80°C (-5°C to +60°C for some models). +45°C (depending on the environment).
Humidity Requirement: Relative Humidity ≤ 95% (non-condensing).
IV. Reliability and Efficiency Parameters
Lifespan and Reliability
Blade Life: ≥ 100,000 hours (affected by operating environment and maintenance).
Mean Time Between Failures: ≥ 5,000 hours (guaranteed by high-efficiency design).
Efficiency Indicators
Volume Efficiency: ≥ 90% (ratio of actual displacement to theoretical displacement).
Mechanical Efficiency: ≥ 90% (ratio of output power to input power).
V. Noise and Weight Parameters
Noise Level: Low Noise Design: Operating noise ≤ 70 decibels (≤ 75 decibels for some models, depending on the application scenario).
Weight
Single pump weight: Approximately 35 kg (25 kg or 46 kg for some models, depending on configuration).
Dual pump weight: Approximately 70 kg (100 kg for some models, depending on model).
VI. Models and Customization Options
Model Identification Rules
Example: PV2R12-XX-XX-F/L-REAA-43
“PV2R12”: Series identifier.
“XX-XX”: Large Pump and small pump displacement (e.g., 10-41 indicates a large pump with 10cc/rev and a small pump with 41cc/rev).
“F/L”: Rotation direction (clockwise/counterclockwise).
“REAA”: Mounting and connection method (e.g., flange type, suction port orientation, etc.).
“43”: Other configuration identifiers (e.g., outlet direction, special customization, etc.).
Customization Options
Displacement Adjustment: Non-standard displacements available upon request.
Rotation Direction: Custom counterclockwise rotation pumps are supported.
Special Media: Suitable for special media such as water-glycol and water-in-oil emulsions.
