The advantages and disadvantages of KCB gear pump comparison: First, the gear pump structure is simple, good workmanship, low cost; but the gear pump is mainly used in low pressure system, its working pressure is relatively low. As the shaft and the bearing pressure imbalance, radial load, limiting its pressure increase. Second, the self-priming performance, and the same flow compared to other types of pumps, compact structure, small size; However, due to large leakage gear pump, resulting in low volumetric efficiency. Third, due to the pump drive part and the gear are basically balanced, at high speeds will not have a larger inertial force, so the speed range; However, the flow pulsation, causing pressure pulsations, the pipes, valves, etc. Vibration, noise.
