Circulating Heavy Oil Well Pump

TheCirculating heavy oil well pump is a improved type of the hydraulic feed-back pump for heavy crude oil.Not only the former advantages have been remained but the inflow valve has been changed to be a annular valve in this kind of pump,which obtains a large flow area and shortens the inflow tubing ,so the inflow resistance is decreased .In the meantime ,for using a long plunger and a short barrel in lower pump,the phenomenon of sand-up can be efficiently avoided .The pump is suitable for 7” casing well,the pumpφ57/φ38 may be used in 5 1/2”casing well.
