The principle Is that the special flat board is adopted as the vane.th rough the physicaI viscous driving and the special structure of flat vane.the medium will form Iaminar flow to pulI the medium from the inlet and push it to the outlet centrifugal flat vane pump is designed to transport fluid medium through the physical viscosity driving and the Iaminar flow formed by the medium Therefore, the medium wilI make bar-shaped flow inside the pump without lmpact.the medium contacting the vane and the flow Iayer of tube wall are static to the vane,and they can move synchronously without friction,so that there is no medium impact that may damage the product,and the laminar flow of pump can be protected Therefore,the flat vane pump can absolutely solve the common problems of produet damage abrasion of vane and pump body caused by media,vane blocking and occurrence of cavitation etc. The special functions of flat vane pump enable the pump to work under severe conditions more reliably more excellently.more economically and more efficiently. Most important of all.it wilI not damage the mediu.It is applicable for transporting media of different viscosity,media of high viscosity,media with solid particles,media requiring that the particles should be protected from being damaged and media requiring soft transportation and not be easily impacted by high speed centrlfugal impact.
