ESP bags
An electric submersible pump (ESP) is used in oil wells to pump fluids to the surface. This ESP system typically comprises a multi-staged centrifugal pump and a motor in an enclosed unit. Elastomer bags (ESP bags) can be used to protect components within the pump from their harsh operating environment.
The primary purpose of an ESP bag is to provide a positive barrier between the well fluids and the clean motor oil within, preventing any ingress of well fluid into the motor. These bags also act as an oil reservoir for the motor, and balance the internal pressure of the well fluid.


PPE packing elements are engineered to face the harsh operating conditions of upstream exploration and production applications.
More about ESP bags
ESP bags from PPE are manufactured from high performance elastomer materials which are proven against high temperatures and high pressures, and the required chemical resistance to well fluids.
For specific OEM requirements, PPE can undertake elastomer material development to meet test regimes and specifications. CO2 and H2S resistant elastomers are available.
PPE also offers engineered support to provide ESP bags in custom geometries, alongside manufacturing in various standard diameters to suit the most common casing sizes.
