pump fluid shown by arrows 360 travels outwards and then inwards along the outwardly extending undulations 330 of the pump rotor 335 and the inwardly formed undulations 340 of the stator 345 in order to add energy to the fluid the upward facing portion of each undulation 330 includes helical blades 365 formed thereupon as the rotor rotates in a clock wise direction as shown by arrows 370 the fluid is acted upon by a set of blades 365 as it travels inwards towards the central portion of the rotor 335 thereafter the fluid travels along the outwardly facing portion of the undulations 330 to be acted upon by the next set of blades 365 as it travels inward below the impeller section 325 is an annular path 350 formed within the pump for fluid traveling upwards towards the surface of the well referring to both fig2 c and 2d the return fluid travels into the pump 300 from the annulus 150 formed between the casing 110 and the work string 120 as the fluid approaches the pump it is directed inwards by packers 360 a b through inwardly formed channels 355 where it travels upwards and through the space formed between the rotor and stator fig2 c where energy or upward lift is added to the fluid in order to reduce pressure in the wellbore therebelow as shown in the figure return fluid traveling through the pump travels outwards and then inwards in the fluid path along the.
