TheParker P3 Series Hydraulic Pumpis a high-performance axial piston variable displacement pump specifically designed by Parker Hannifin for mobile machinery and mobile hydraulic systems. Below is a detailed introduction to its key features:
------
I. Key Features
1. High-Pressure Performance:
• Rated Pressure: 320 bar (some models up to 350 bar).
• Peak Pressure: 370 bar.
• Capable of stable operation under high-pressure conditions, meeting the demands of heavy-duty construction machinery.
2. Compact Design:
• Small size and lightweight, suitable for installation in space-constrained mobile equipment.
• Flat pump body design eliminates the need for offset gearboxes, facilitating installation in narrow spaces.
3. Low Noise and Vibration:
• Unique pressure pulsation chamber design reduces outlet pressure fluctuations by up to 50%.
• Lowers noise levels by 5–8 dB, providing a quiet and efficient working environment.
4. High Self-Priming Capability:
• High self-priming speed, suitable for applications requiring self-priming and operation at high altitudes.
• The P3 series incorporates a built-in suction port pressurization device to enhance the pump's self-priming ability and operational efficiency.
5. Multiple Control Options:
• Offers load-sensing, pressure limiters, power control, and other control methods to meet diverse application requirements.
• Supports modular controllers for easy conversion and integration.
6. Easy Installation and Maintenance:
• Complies with SAE and ISO standards for mounting flanges and ports, facilitating integration with existing systems.
• Multiple housing drain port designs accommodate various installation orientations.
• Modular design simplifies troubleshooting and component replacement.
