Working Principle：

The high-pressure rolling bearing gear pump is mainly composed of driving gears, driven gears, pump body, pump cover, rolling bearings and other components. Its working principle is that a pair of meshing gears rotate in a sealed pump body. When the meshing teeth on one side of the suction chamber gradually separate, the volume of the suction chamber increases, the pressure decreases, and the liquid is sucked into the pump; the liquid is pushed to the discharge chamber by the gears in the tooth grooves in two ways. As the gears continue to mesh, the liquid is squeezed from the discharge chamber into the discharge pipe, thereby realizing the transportation of the liquid.

Application Areas：

• Engineering machinery: such as excavators, loaders, bulldozers, cranes, etc., used to provide high-pressure oil for the hydraulic system to drive various working devices to achieve excavation, loading, bulldozing, lifting and other operations.

• Coal mining machinery: widely used in coal mining machines, scraper conveyors, hydraulic supports and other equipment to provide power for the hydraulic systems of these equipment to ensure the normal operation and work efficiency of the equipment.

• Construction machinery: such as concrete pump trucks, road rollers, pile drivers, etc., high-pressure rolling bearing gear pumps provide high-pressure oil for their hydraulic systems to achieve functions such as concrete transportation, road compaction, and pile foundation construction.

• Other industrial fields: It can also be used in the hydraulic systems of metallurgy, chemical industry, shipbuilding, machine tools and other industries to transport various oils, emulsions, lubricants and other media to meet the hydraulic transmission needs of different industrial equipment.

High Pressure Roller Bearing Gear Pumps are the workhorse in many industrial high-pressure hydraulic and fluid transfer applications due to their rugged rolling bearing support structure, excellent high-pressure performance, high load capacity and long life.
