reo(a) The electric submersible progressive cavity pump (ESPCP) is a new breakthrough in artificial lift system recent years, which combines the flexibility of the progressing cavity pump with the reliability of the electric submersible motor to handle your most difficult artificial lift. It has wide fluid range, more suitable for deviated well, horizontal well, especially with viscous crude oil, high sand cut and gas oil. The wear of tubing and sucker rod could be eliminated and energy cost is reduced efficiently.
