Variable Speed

Introduced in 1995, FE PETRO® brand variable speed submersible turbine pumps (STPs) were the first of their kind for the petroleum industry. With faster fill times during peak hours and power savings during non-peak hours, FE PETRO® brand variable speed STPs allow you to maximize profits while minimizing operating expenses.



  • Higher flow rates. The variable speed controller ramps the STP up and down as needed to provide optimal flow rates at fueling points. The result is a more consistent customer experience.
  • Efficient energy consumption. Because a variable speed system is constantly providing only the necessary power to achieve desired flow rates, the system only consumes as much energy as is needed.
  • Reduce hydraulic hammer. Hydraulic hammer is a sudden pressure spike resulting from a stoppage in flow in a pressurized piping system. This can be exaggerated in fixed speed systems. A variable speed system significantly minimize the effects of hydraulic hammer.
