The structure and working principle are very similar. They are also often confused. But they do the exact opposite. A hydraulic pump converts mechanical energy into pressure energy and sends oil to places where it is needed. A hydraulic motor converts pressure energy into mechanical energy. The oil drives the blades of the engine, driving it and doing its job.
Hydraulic motors are used in literally every single hydraulic power transmission system. A hydraulic motor is the device that converts mechanical energy into hydraulic energy, which is a combination of pressure and flow. Hydraulic motors are used on every conceivable mobile or industrial hydraulic machine.
Hydraulic motors are used on excavators, cranes, loaders, tractors, vacuum trucks, forestry equipment, graders, dump trucks, mining machinery, etc. Mobile applications use hydraulic motors more prolifically than other industrial machines, because electric actuators are generally not used for mobile machinery. The more severe the application, the more likely it will be powered by a hydraulic motor.
At Capital dredge parts we have these hydraulic motors for sale: gear, piston and vane. The pumps are mainly used in industry, shipping and mobile sector. We sell used hydraulic motors from Bosch, Brueninghaus and commercial hydraulics and Parker, among others. In addition, we have dozens of other brands.
