Description

About HGP Series Twin-Stage High-Pressure Gear Pumps
The Dongxu HGP Series dual-pump high-pressure gear pumps feature a compact, coaxial dual-pump design. They incorporate an aluminum alloy pump housing paired with helical, low-noise gear sets. Each pump has a rated pressure of up to 16 MPa and provides independent dual-line oil supply. The front and rear pump housings can be customized with different displacement combinations as needed. These pumps are lightweight, low-noise, highly efficient, and highly reliable, and their standard flange and shaft extension designs ensure easy installation.

Key Features

Dual independent oil supply for flexible operation: The two pump units can provide independent flow and pressure to different circuits within the system, meeting the demands of multi-circuit hydraulic systems while reducing costs.
Helical-tooth design for quiet, high-pressure operation and stable performance: The smooth meshing of helical gears minimizes internal leakage under high-pressure conditions, ensuring reliable operation.
Lightweight and compact design for easy installation: Lightweight and with rapid heat dissipation, the overall dimensions are shorter than those of two separate single pumps.
Extensive range of specifications for strong adaptability: Supports various displacement combinations, including HGP-2A/3A and other specifications.
High cost-effectiveness and low maintenance costs: Simple structure with no complex or vulnerable components; maintenance-free design ensures a long service life.

Application

Construction Machinery: Main working circuits for skid-steer loaders, excavators, and forklifts + steering/brake auxiliary circuits.
Agricultural Machinery: Hydraulic lifting and steering dual-circuit systems for tractors and harvesters.
Hydraulic Power Units: Equipment with multiple actuators requiring dual oil supply lines, such as machine tools with dual circuits for clamping and feed.
Automation Equipment: Multi-station hydraulic equipment, with front and rear pumps providing independent flow control for different stations.

Packaging & Delivery
Protective Industrial Packaging: Each pump is carefully packaged in reinforced, moisture-proof materials to prevent surface damage and shaft corrosion during transit.
Global Fulfillment: Factory-direct dispatch with optimized logistics support, ensuring reliable and timely delivery to international destinations.
