Abstract：A novel impeller pump has been developed.The magnets were inlaid ontothe impeller,the coil was winded around the pump housing.As the current is introducedinto the coil,the impeller rotates to pump the fluid.Two magnetic bearings weredevised to replace the mechanical bearing,thus the rotor and stator has no contact,no friction and no wear.All the fluid contacted surfaces with stainless coatingswere immersed in the liquid,there is no sealing in the pump.The impeller vane wasdesigned according to a three-dimensional analytical method.This novel impellerpump promises to be able to operate continuously,durably and reliably.
