Parker PV Series Hydraulic Pumps
The Parker PV Series Hydraulic Pumps are high-performance swashplate-type axial piston variable displacement pumps designed by Parker Hannifin specifically for high-pressure, heavy-duty industrial applications. Below is a detailed introduction to this series of hydraulic pumps:
------
I. Key Features
1. High-Pressure Output:
• Rated operating pressure of 350 bar, with some models reaching up to 420 bar, meeting the demands of various high-pressure hydraulic systems.
2. Convenient Flow Adjustment:
• Utilizes a swashplate variable mechanism to adjust the pump's displacement by changing the swashplate angle, enabling stepless flow regulation.
3. High Volumetric Efficiency:
• Volumetric efficiency up to approximately 95%, with total efficiency around 90%, reducing energy loss and improving overall system efficiency.
4. Compact Structure:
• The pump body is robust and optimized through Finite Element Analysis (FEM), helping to reduce noise levels while minimizing size and weight for easy installation and maintenance.
5. Multiple Variable Control Forms:
• Offers various variable control options, such as standard pressure regulators and power regulators, facilitating adjustments according to actual needs.
6. Through-Shaft Drive Configuration:
• Supports single-pump and multi-pump series installations, enabling complex hydraulic system configurations.
7. Low-Noise Design:
• Adopts pre-compression volume technology combined with a 9-piston design to effectively reduce flow pulsation and noise levels, enhancing operational smoothness.

II. Technical Specifications
• Displacement Range: From 16 to 270 ml/rev, covering a wide range of flow requirements.
• Rated Operating Pressure: 350 bar, with some models reaching up to 420 bar.
• Minimum Operating Speed: 300 revolutions per minute, ensuring stable operation at low speeds.
• Case Drain Port Orientation: Typically requires the case drain port to be oriented upwards for optimal heat dissipation and lubrication.
------
III. Application Areas
The Parker PV Series Hydraulic Pumps are widely used in various industrial sectors requiring high-pressure, large-flow hydraulic systems, including but not limited to:
• Construction Machinery: Such as excavators and loaders, providing stable hydraulic power support.
• Metallurgical Industry: Used in hydraulic systems for blast furnaces and converters, meeting the demands of high-temperature, high-pressure working environments.
• Petrochemical Industry: Providing reliable hydraulic power in oil drilling, refining, and other processes.
• Shipbuilding: Utilized in hydraulic systems for ship steering gear and anchor winches, ensuring safe navigation.
• Injection Molding Machines and Die Casting Machines: Offering high-pressure, rapid hydraulic response to meet precision molding requirements.
