ROBUST® ESP
The ROBUST® Electric Submersible Pump System consists of several components that are carefully selected to create the most economical and efficient solution for each set of well conditions.
Surface Equipment
Above ground a system controller combined with a Variable Frequency Drive and related transformer or the ROBUST® Variable Frequency Generator provide controlled power supply to the ESP.
Power Cable & Motor Lead Extension
The electrical main cable and the flat cable motor lead extension with pothead connect to the surface equipment with the ESP motor and well monitoring device.
Drain Valve & Check Valve
Other protective devices are located above the pump discharge. These include the check valve that closes on backflow and prevents back spinning and the drain valve that allows for pulling the ESP without a wet tubing string.
Pump
The pumping unit itself consists of the multi-stage centrifugal pump housed in a pressure sleeve with the capability of producing capacities up to 100,000 BPD (16,000 m3/d) from depths of up to 15,000 ft (4,575 m).
Intake/Gas handler/Gas Compressor
Immediately below the pump is the intake combined with a gas handler if required. The gas handler allows for trouble free operation in well conditions with free gas contents of more than 10% to 20%. The ROBUST® Gas Compressor can handle up to 45% of free gas.
Protector
Located between the motor and pump intake is the protector. The protector isolates the motor from the well fluid and contains the high capacity thrust bearing.
Motor
The high quality electrical motor for well casings 4-1/2” (114 mm) and larger is a squirrel cage, two pole, three phase induction motor. The motor turns at a speed of approximately 3,500 RPM at 60 HZ and 2,900 RPM at 50 HZ.
Sensor
The down hole sensor is located below the motor and transmits important well and system data via the main power cable to the surface.
