CBK1 series high-pressure gear pumps adopt floating axial compensation structure, DU bearing with high bearing capacity and aluminum alloy shell structure with high strength. The maximum pressure is up to 25MPa, the rotary speed ranges from 600 to 3000r/min, and the output volume is between 4 and 25ml/r.The pump has the characteristics of high pressure, wide speed range, multiple specifications for output volume, small volume, light weight, reliable operation and convenient maintenance, etc.. There are five kinds of connection for shaft extension, namely, flat key, rectangular multiple keys, involute multiple keys, DP multiple keys and cone-axis screw thread. The oil port is equipped with flange connection CBK1 gear pump. In addition to single pump and duplex pump, they can also be composed of triple and quadruple pump, and can also be carried with safety valve for the arbitrary use of host machine. As a power source, it is widely used in construction machinery, lifting and transport machinery and mining machinery, making itself the best choice for small and medium-sized hydraulic pumping stations.
