Industrial Excellence
& Technical Mastery

Redefining fluid power through high-performance gear pump architectures.

As a global leader in double gear pump hydraulic systems, we specialize in the manufacturing of precision-engineered fluid power components. Our position in the general equipment manufacturing sector is defined by a commitment to zero-leakage technology and extreme durability, ensuring that every pump can withstand the harshest industrial environments while maintaining peak output.

The technical edge of our double gear pump hydraulic range lies in the synchronized dual-gear mechanism, which optimizes fluid displacement and minimizes pressure pulsation. By utilizing aerospace-grade alloys and advanced heat-treatment processes, we reduce friction and wear, resulting in an extended service life and significantly lower maintenance costs for end-users.

Frequently Asked
Questions

Expert answers to common technical and commercial inquiries.

01

What is the primary advantage of a double gear pump over a single gear pump?

The double gear pump design provides smoother flow with significantly lower pressure pulsations, reducing vibration and wear on the rest of the hydraulic circuit, while often offering higher volumetric efficiency.

02

Which fluids are compatible with your double gear pump hydraulic systems?

Our pumps are designed for hydraulic oils, lubricants, and various synthetic fluids. For corrosive or high-viscosity chemicals, we offer specialized alloy coatings to prevent erosion.

03

How do you ensure the longevity of the gear teeth?

We utilize advanced carburizing and induction hardening processes, creating a hard, wear-resistant outer shell and a tough, ductile core to handle shock loads.

04

Can these pumps be customized for specific flow rates?

Yes, we provide full OEM customization. By adjusting the gear diameter and width, we can tailor the displacement to meet your exact volumetric requirements.

05

What is the typical maintenance cycle for your pumps?

Depending on fluid cleanliness, most of our pumps only require seal inspections every 5,000 to 8,000 operating hours, thanks to our high-grade metallurgy.

06

Do you provide technical support for system integration?

Our engineering team provides full integration support, including flow calculations, mount design, and pressure valve configuration for your specific machinery.
