Electrical Submersible Pump
Electrical Submersible Pump (ESP) is an artificial lift method to lift fluids from the wells.
Electrical Submersible Pumps are used to pump off the oil wells and produce water from the water source wells.
A typical submersible pumping unit consists of an electric motor, a seal section, an intake section, a multistage centrifugal pump, an electrical cable, a surface-installed switchboard, a junction box, and transformers .
750+ ESP models are grouped into the ESP catalog.
ESP Performance Curves
The performance curves of ESP represent the relationship between flow rate capacity and:
- Head capacity
- Pump efficiency
- Brake Horsepower
ESP Performance Curves also show Best Efficiency Point (BEP) and ESP operating range.
ESP Performance Curves are used for ESP design and sizing.
These curves are for a fixed power cycle i.e. 50Hz, and can be changed with variable frequency controllers.
