    What is a vane pump? Vane pump is a common centrifugal pump in various industries and application scenarios, also known as centrifugal vane pump. A vane pump pumps liquid or gas from one area to another through its rotating blades. This type of pump usually consists of a rotating impeller, pump housing, shaft (bearing) and sealing device. When the impeller rotates, it creates centrifugal force, so that the liquid or gas is thrown to the outlet of the pump. A vane pump works like a fan. When the impeller rotates, the liquid or gas is drawn into the center of the pump, and then thrown to the exit of the pump by the action of the rotating blade. This pump is suitable for a variety of applications, including industrial, construction, agriculture, domestic use, medical equipment, automotive industry, to transport water, oil, chemicals, air and more.   What is a hydraulic gear pump? Hydraulic gear pump is a common hydraulic transmission device, should be a wide range of industrial machinery, engineering machinery, agricultural machinery and other scenes; It is used to convert mechanical energy into hydraulic energy, providing pressure and flow to the hydraulic system. Hydraulic gear pump is mainly composed of gear, bearing, housing and other components. The working principle of the hydraulic gear pump is to suck in the liquid and discharge it through the rotation of the gear. Gear pumps usually have multiple structures and a variety of materials, their advantages include simple structure, small size, light weight, high efficiency, so it is widely used in many hydraulic systems.   What is the difference between a vane pump and a hydraulic gear pump? 1. Different structures: The shell of the gear pump has a pair of internal and external meshing gears, while the vane pump is composed of a rotor, a stator and a blade. 2. Different characteristics: The volume of the gear pump is small, the structure is simple, the cleanliness of the oil is not strict, and the price is relatively cheap; However, the bearing force of the gear pump is unbalanced, the wear is serious, and the leakage is large. The vane pump has uniform flow, small leakage, and can work under high pressure, mostly used in high-power hydraulic systems; However, the structure is complex, the material and processing accuracy are required to be high, the price is high, and the cleanliness of the oil is required to be high.   If you’re looking for cost-effective and timely pump replacement options, you’re looking for us.
