With the development of national petroleum industry and offshore oilfield production, offshore platforms are in great need of submersible seawater pumps for the uses of fire protection, water injection and cooling. The submersible seawater pump is an ordinary type of seawater lifting equipment. Since seawater motors and pumps are running under the sea, they are featured with fire protection function, space-saving design, easy installation and reliable operation. QJH series seawater submersible pumps are developed in order to meet specific requests from offshore platforms. BEKENFLO ’s seawater submersible pumps are used for the applications of up to 800mm casings, 10-500 m³/h flow rate，20-240 m head and 1.2-350kW power. BEKENFLO is providing customized seawater submersible pumps as per customers’ requirements. |

ESPCP (Electrical Submersible Progressing Cavity Pump) System
ESPCP is the recently developed oill lifting equipment featuring the advantages of ESP and PCP. They eliminate the rod wearing
and offer a more efficient and cost saving solution in terms of operation and maintenance.
ESPCPs are suitable for a wide range of well conditions including viscous, gassy and abrasive applications.
ESPCP is the submersible motor driven progressing cavity pumping system. Integrating designing and functional advantages, they save the energy by 30%~60% when compared with rod pumps. Since it provides deeper pump setting depth than that of rod
pumps, they also can be used in the various applications, including heavy oil wells, sand producing wells, gas wells, deviated wells and horizontal wells.
ESPCPs are widely used for coalbed methane dewatering. They can handle abrasives, such as coal fines, while maintaining production efficiency with low pump intake pressure.
