Tractor Pump

Among the existing hydraulic pumps, the working pressure of gear pumps is second only to that of plunger pumps. In addition, they are small in size and low in price, so they are widely used in mobile equipment and vehicles as pressure oil sources for hydraulic working systems and steering systems. On the other hand, due to the large speed and displacement range of the gear pump, strong oil absorption capacity and low cost, it is also often used as an auxiliary pump for various hydraulic systems, such as the supplementary pump in the closed circuit, and the pilot control system. The low pressure control oil source in the middle and so on. However, in the field of fixed hydraulic equipment, due to the large flow pulsation, high noise and limited life of external gear pumps, they have become increasingly unpopular as main pumps, and their uses are limited to auxiliary pumps and pre-pressure pumps operating at low pressure. On the contrary, the internal gear pump is one of the hydraulic pumps with low noise and good comprehensive performance. Except for the slightly higher price, it is almost superior to the external gear pump in other aspects.
