Hydraulic Pumps & Motor Repairs FAQ's

The following are the differences between a hydraulic motor and a hydraulic pump:

  • Hydraulic Motor – A hydraulic motor takes fluid power (hydraulic pressure) and turns it into mechanical power (torque). It’s used to move things such as wheels, arms or conveyors.
  • Hydraulic Pump – A hydraulic pump takes mechanical pressure and converts it into fluid power. This fluid is then pumped throughout the hydraulic system.
  1. Gear Pumps – These use two meshing gears to trap and then move fluid, commonly used in mobile applications due to their simplicity, compact nature and ability to handle high pressures.
  2. Vane Pumps – Spring-loaded vanes slide in and out of a rotor, creating expanding and contracting chambers that draw in and expel fluid. Often found in industrial machinery, machine tools etc. due to their ability to operate quietly in moderate to high pressure.
  3. Piston Pumps – Pistons reciprocate within cylinders to displace fluid, highly ideal for high-pressure applications such as heavy construction equipment.
  4. Fixed Displacement – These produce constant flow levels regardless of systemic pressure.

A gear motor is a type of motor that utilises gear meshing as a means to convert hydraulic fluid power into mechanical energy.

External Gear Motors are the most common type and feature two external gears. When pressurised fluid enters the motor, the gears are forced to rotate and generate torque. Internal Gear Motors are a less common type, with one external and one internal gear. Fluid flows between the teeth of the gears, causing them to rotate and transmit torque to the output shaft.

One of their main advantages is a high starting torque, generating significant torque even at low speeds.
