Product Catalog | Hydraulic Gear Pumps

In our gear pump product catalog, we offer a wide selection of high-efficiency and durable hydraulic gear pumps designed for construction machinery, agricultural equipment, mining machines, and industrial systems. These gear pumps utilize advanced technology to ensure smooth and stable fluid delivery, providing excellent wear resistance and high efficiency. They are ideal for transporting high-viscosity fluids and precise flow control in demanding applications.

Types of Gear Pumps:

External Gear Pumps: Consist of a pair of external gears that mesh outside the pump housing. This design features a simple structure, easy maintenance, and high output pressure, making it widely used in excavators, wheel loaders, bulldozers, forklifts, and tractors. However, they tend to be larger in size.
Internal Gear Pumps: Consist of an internal gear, an external gear, a crescent separator, and a pump housing. This design reduces noise and saves space, making it suitable for low-pressure applications that require steady fluid delivery, such as agricultural machinery and industrial automation equipment. However, they have a more complex structure and can be more challenging to maintain.
