As leading Hydraulic Gear Pump Manufacturers in China, we offer a comprehensive range of high-quality gear pumps suitable for diverse hydraulic systems. Our expertise spans external gear pumps, internal gear pumps, and fixed displacement gear pumps, offering durable performance, stable flow, and precise pressure control. Whether your application demands high pressure, smooth operation, or the ability to handle thin liquids, our pumps are designed to meet the rigorous requirements of modern hydraulic equipment.
We are recognized among top hydraulic gear pump manufacturers and gear pump suppliers for our consistent quality, extensive product range, and customized solutions tailored to diverse industrial needs.
External gear pumps are robust and widely used in medium- to high-pressure hydraulic systems. They provide consistent output and are ideal for industrial machinery, mobile equipment, and lubrication systems.
Internal gear pumps offer smooth, pulse-free flow, making them suitable for applications that require gentle handling of fluids, such as lubrication, chemical processing, and thin oil circulation.
Fixed displacement gear pumps deliver a constant flow per shaft revolution, offering simplicity, durability, and reliability for systems where steady performance is essential. They are well-suited for high-pressure environments and are available in configurations like double gear pump or tandem gear pump assemblies, allowing multiple hydraulic circuits to be powered efficiently from a single unit.
Our hydraulic gear pumps are designed to be compatible with many internationally recognized hydraulic brands, providing reliable replacement options for OEM equipment and maintenance markets.
Common replacement or equivalent brands include:
Bosch Rexroth Gear Pumps
Parker Gear Pumps
Danfoss Gear Pumps
Eaton Vickers Gear Pumps
Casappa Gear Pumps
Permco Gear Pumps
Shimadzu Gear Pumps
Marzocchi Gear Pumps
Bucher Hydraulics Gear Pumps
Hydreco Gear Pumps
