KCB Gear pump is a pair of meshing gears will be a closed chamber is divided into two parts-into oil cavity (low pressure cavity) and out of the oil cavity (high pressure cavity) , through the meshing gear rotation of low pressure cavity oil pressure to high pressure cavity, thus the function of the positive displacement hydraulic pump is completed. The gear pump has the advantages of simple structure, convenient manufacture, low price, small volume, light weight, good self-priming performance, insensitive to oil pollution, reliable work, long service life and easy maintenance. Widely used in mining, metallurgy, construction, aviation, navigation, agriculture and forestry and other machinery.
