Floating configuration with axial support in the section (optimized for limited content of abrasive particles in reservoir fluid)
-
Floating configuration without axial support in the section (optimized for high concentration of abrasive particles in reservoir fluid)
-
Packet assemble scheme (optimized for severe conditions with high concentration of abrasive particles in formation fluid)
-
Compression configuration (optimized for severe conditions with high temperature of reservoir fluids and with high concentration of solid particles and gas)

Gas Separators
- reduce the amount of free gas in the formation fluid at the pump intake;
- protect from gaslocks appearing;
- provide stable performance of ESP;
- Reduces MTBF (minimum time before failure). -
Dispensers
- converts reservoir fluid into the homogeneous mixture;
- eliminates or minimizes the influence of free gas on stages;
- reduce flow vibration and pulsation in oil well tubing;
- provides the the pump KPI efficiency;
- reduce spurging. -
Gas Separators - Dispensers
- reduce the amount of free gas;
- dispense gas inclusions;
- converts reservoir fluid into the homogeneous mixture at pump intake ;
- installed in wells with especially high GOR (gas to oil ratio), where nither gas separators, nor the dispensers can't provide stable ESP performance.
