Progressive Cavity PumPs
In recent years, complicating factors, such as solids content, scaling, high GOR, high viscous flu-
ids, low production rates, etc., have extended impact on the overall performance of artificial lift equip-
ment. ESP application in such operating conditions is limited.
The most efficient artificial lift method that copes with these complicating factors is progressive
cavity pumping, since it brings a viable solution to oil recovery issues for 70% of difficult wells.

The following design types of Submersible Progressive Cavity Pumps are available:
Single Electric Submersible Progressive Cavity Pump EOVNB series,
Twin-opposed Electric Submersible Progressive Cavity Pump EVNB series,
Twin-opposed Electric Submersible Progressive Cavity Pump with fixed direction of residual
thrust load EVNFB series.
Operating components of ESPCP are a stator filled with elastomer and a steel rod. Elastomer ma-
terial and clearance between the rod and stator are selected based on specific operating conditions.
