Analyze the advantages of vortex pumpsThe vortex pump has the advantages of small size and light weight. It has great advantages in the marine equipment.It has self-priming capability or self absorption with simple devices.The vortex pump has a steep drop head characteristic curve, so it is insensitive to the pressure fluctuation in the system.Some vortex pumps can realize gas-liquid mixed transportation. High temperature has important significance for the liquid pumping gas containing volatile liquid and vapor pressure is very high.Vortex pump structure is simple, casting and processing are easy to achieve, some vortex pump parts can also use non-metallic materials, such as plastics, nylon, molded impeller, etc..
