II. Key Features
1. Material & Construction
• Three-piece cast iron design: The pump body, end cover, and gears are all made of cast iron, ensuring durability under high-pressure and high-load conditions. The fully disassemblable structure simplifies maintenance and reduces long-term costs.
• Modular port configurations: Supports multiple port and mounting flange options for flexible integration into various hydraulic systems.
2. Performance Specifications
• Pressure range: Rated pressure up to2,500 psi (172 bar), with some models reaching3,500 psi (241 bar), surpassing standard gear pump capabilities.
• Flow rate & speed: Flow rates range from39–48 gpm (148–182 L/min), with a maximum rotational speed of2,400 rpm, meeting the rapid actuation demands of heavy equipment.
• Temperature tolerance: Operates in hydraulic oil temperatures from-20°C to 80°C, adapting to extreme environments.
3. Critical Components
• High-pressure shaft seals: Utilizes Taiwanese-brand high-pressure seals to prevent leaks and extend service life.
• Pressure-balanced thrust plate: Balances axial forces to reduce wear and improve efficiency.
• Heavy-duty roller bearings: Features U.S.-branded bearings for long-lasting performance, even in rugged dump truck applications.
4. Safety & Control
• Integrated relief valve: Factory-set to2,000 psi or 2,500 psito prevent system overpressure and ensure equipment safety.
• Manual/pneumatic control options: Supports cab-mounted manual control or optional pneumatic shift control for enhanced operational flexibility.
