HYDRAULIC GEAR PUMP is widely used because of its simple manufacturing process. Although the manufacturing of internal gear pumps is more complicated than that of external gear pumps, it has large displacement and small flow and pressure pulsations under the same size. Generally, the noise of a HYDR

Adopting the principle of internal gear mesh, the inner and outer gears are close to one side, and the other side is separated by the "crescent plate" on the pump cover. The active inner gear on the main shaft drives its outer gear to rotate in the same direction, and the gears separate from each ot

HYDRAULIC GEAR PUMP is widely used in various hydraulic systems due to its compact structure, small size, good self-priming performance, insensitivity to dirt, reliable operation, long life, easy maintenance and repair, and low cost. The current development trend of HYDRAULIC GEAR PUMP is high press
