The Modern Gear Pump for Earthmoving Machines

The hydraulic system is of utmost importance in the overall performance of earthmoving machines. The heart of any hydraulic system is the pump. The modern gear pump is available in a wide range of flow rates and pressure ratings. This paper will deal with the major factors to be considered in the selection of a pump, including capacities and pressure ranges available, life, fluid compatability, efficiency, cleanliness requirements, etc.

A brief look at the future will show that gear pump technology is in a position to keep pace with the rapid advance in flow and pressure requirements of the earthmoving industry.
