HGP Series External Gear Pumps (Double Pump/Tandem Pump)
Request a Quote
The double high-pressure gear pump utilizes a dual-pump integrated design. It features a high-grade aluminum alloy body, equipped with oilless bearings and Viton oil seals, offering resistance to high temperatures, high speeds, high pressures, and high torque, making it suitable for extreme working conditions.
- Ultra-high efficiency: Total efficiency of over 95%, significantly reducing energy consumption and optimizing system operating costs.
- Compact integration: Can directly integrate with hydraulic motors, saving space, simplifying system design, and facilitating installation and maintenance.
- Dual-pump collaborative operation: Integrates two independent pump bodies, capable of simultaneously providing stable flow to multiple hydraulic circuits, optimizing system efficiency.
- High-pressure output: Supports pressures of up to 250 bar or higher, meeting demanding power requirements.
- Precise flow distribution: Ensures uniform, continuous fluid delivery, adapting to the precise control needs of multi-circuit hydraulic systems.
- Flexible adaptability: Supports various media, including high-viscosity oils, lubricants, and chemical fluids.
