Tractor Hydraulic Gear Pumps

The tractor hydraulic gear pumps adopt a double-gear structure (the driving gear and the driven gear).  The engine of the tractor drives the driving gear to rotate, which in turn causes the driven gear to rotate synchronously. When the gears mesh, the volume between the teeth on the intake side increases, creating a vacuum to draw in oil. The volume between the teeth on the exhaust side decreases, compressing the oil, which is then discharged through the high-pressure chamber of the tractor hydraulic gear pumps bodies to achieve the circulation and pressure increase of the hydraulic system oil.

Application scenario

Hydraulic suspension system: Controls the lifting and lowering of agricultural tools, precisely adjusts the plowing depth.

Steering system: Provides power for the full hydraulic steering device, enabling smooth and flexible operation.

Auxiliary operations: Drives hydraulic motors (such as straw shredding devices, loading machinery).

Installation notes

Before starting the system on a continuous basis, we suggest to adopt as follows simple precautions.Check for the direction of rotation of the pump to be consistent with the drive shaft one,be sure no reversion revolved.Check for the proper aligment of pump shaft and motor shaft,it is necessary that the connection does not induce axial or radial loads.

Check if contact area between seal ring and shaft is clean,remove all dirt, chips and all foreign bodies form flanges connecting inlet and delivery ports, dust could provoke quicker wear and leakage.

Ensure that intake and return pipes ends are always below fluid level and as far from each other as possible.Fill the pump with fluid, and turn it by hand.Disconnect pump drain during startup to bleed air off the circuit.Always avoid or limit load starting for pump longer life.

The tractor hydraulic gear pumps we produce are sold directly by the manufacturer. We have an abundant supply of them and can also customize them according to the specifications and sizes. They are widely used and can meet the needs of most vehicle models.
