Abstract The advantages and disadvantages of manual and electric sprays,and the characteristic of foreign-made electric spray pump were discussed.A new type of double action roller rotary pump was developed which belongs to positive displacement rotary pump.The new pump uses rolling friction to replace sliding friction and thus has lower frictional loss.Meantime,it uses symmetric structure with double inlet and outlet,which improves the radial force balance.All the above increase the service life.Eighth-power curve was used for drawing the transitional curve of the stator.Compared with other products,this new pump shows high efficiency and low noise.
