Fill Cars Faster with MagShell®
Available on FE PETRO® 2 Hp and 4 Hp PMAs, the MagShell® provides an expanded flow area, creating significantly higher flow rates equivalent to having one more nozzle open during peak operating times.
A 4 Hp variable speed STP with MagShell® provides the highest flow rates of any single 4" submersible pump available on the market today.
Corrosion Control™
When combined with an FE PETRO® pump, the Corrosion Control™ Water Separator provides proactive in-tank corrosion control by removing tank bottom corrosion contributors including water and acid while taking up minimal space inside the containment sump
Remove Water & Acid
The Water Separator removes any water/acid mixture off the bottom of the diesel tank and separates it from the clean fuel. The water/acid is collected in the vessel for disposal while the clean fuel is directed back into the tank.
Powered by the Pump
The Water Separator uses the flow of fuel created by a 4" FE PETRO® submersible turbine pump to generate a vacuum which suctions the tank bottom.
Easy Maintenance
The element-free vessel has no filter to change, eliminating ongoing replacement costs. The collected water/acid mixture is removed 2-3 times per year by a service technician, keeping the tank clear of the harmful corrosion-causing mixture.
System Automation
Control and monitoring are managed through an EVO™ Series console, which automates separator run times and signals when the vessel is ready for emptying. Get access to system data including Water Separator status, water levels, flow status, and more.
Filter Fuel Without Sacrificing Performance
Stop debris from entering the pumping system and causing system damage or slowdowns. An Intake Filter Screen (IFS) provides fuel filtration for the entire system down to about the size of a grain of sand.
The self-cleaning IFS keeps harmful debris, sediment, and tank corrosion from entering the pumping system, minimize service events including dispenser filter changes.
Maximize efficiency, reliability, and control with intelligent pump controllers. Designed to optimize fuel flow and system performance, these intelligent controllers provide advanced functionality to meet the demands of any fueling operation.
MagVFC™ Variable Speed Controllers
For applications with varying demand, the MagVFC™ variable frequency controller provides control for both 2 Hp and 4 Hp variable speed STPs.
The MagVFC™ controller adjusts the pump's speed to maintain optimal flow rates, resulting in faster, more consistent fueling compared to fixed speed systems, all while minimizing energy consumption and costs.
Automatically adjusts pump speed dynamically for optimal flow rates
Provides more consistent fueling compared to fixed speed systems
Maintains stable performance with fluctuating demand
Reduces energy consumption and system wear
Compatible with FE PETRO® 2 Hp and 4 Hp variable speed pumps
Guardian Series™ Fixed Speed Controllers
The Guardian Series™ controllers provide intelligent submersible turbine pump (STP) control and protection for fixed speed pumps.
Built upon the solid FE PETRO® brand smart controller platform, Guardian Series™ controllers feature an enhanced user interface, greater functionality, and facilitate higher performance compared to standard control boxes.
Intelligent submersible turbine pump control and protection
Enhanced user interface for easy setup & troubleshooting
Overload and underload protection to prevent pump damage
Dry-run detection to avoid unnecessary wear
Compatible with FE PETRO® single- & three-phase fixed speed STPs
The FE PETRO® MagVFC™ Variable Frequency Pump Controller brings advanced performance and efficiency to fueling operations. Designed to optimize flow rates, this intelligent controller adjusts pump motor speeds in real time to maintain consistent fuel flow, even during peak demand.
With faster fill times during peak hours and power savings during non-peak hours, FE PETRO® 2 Hp and 4 Hp variable speed submersible pumping systems allow operators to maximize profits while mitigating operating expenses.
Variable speed pumps ensure consistent flow rates, even during peak demand, providing customers with faster fueling and a smoother experience at the dispenser, reducing wait times and improving overall satisfaction.
Minimize sudden pressure spikes, known as hydraulic hammer, that occur during sudden stoppages in flow. These spikes can be exaggerated in fixed speed systems and lead to accelerated equipment wear and damage.
Turbine Pump Interface (TPI) is a powerful tool that creates a network between intelligent pump controllers and EVO™ Series fuel management system consoles.
Turbine Pump Interface
Through TPI, the EVO™ has access to the submersible pumping system status and the capability to react with intelligence that pump controllers alone cannot. The devices share data to provide enhanced system capabilities.
Detect and automatically react to offline systems
Faster pump reset and avoided downtime
Enable remote troubleshooting
Prevent maintenance calls and trip charges
Prevent fuel runouts, dry runs, and tank overfills
Preventing and detecting fuel leaks is critical for maintaining compliance and protecting the environment. Leak detection systems help identify leaks early, reducing the risk of costly downtime and regulatory fines.
Mechanical Leak Detectors (MLD)
MLDs provide a simple, reliable way to detect leaks in pressurized fuel lines. These devices respond to pressure drops by restricting flow, alerting operators to potential leaks without requiring electronic monitoring.

Standard Features
Variable Speed
With faster fill times during peak hours and power savings during non-peak hours, variable speed submersible pumping systems allow you to maximize profits with consistent flow rates while mitigating operating expenses.
MagShell®
The patented stainless steel MagShell® is designed to maximize flow rate capabilities, potential throughput, and profits. By expanding the pump motor shell, the MagShell® increases the area for product flow by 45%.
Variable Length
The patented telescoping pump shaft lets installers adjust the length of the pump onsite for the perfect fit.
Active Air Eliminator
FE PETRO® STPs come standard with active air elimination, which eliminates air through the highest point in the pump head at all times when the pump is running, assuring air does not pass into discharge piping.
Safety and Ease of Maintenance
FE PETRO® STPs include a contractor electrical disconnect, which requires loosening only one bolt, allowing motor wiring to be disconnected without venting the dangerous tank vapors into the sump when servicing FE PETRO® submersible products.
Simple Servicing
If ever required, the pump can be easily removed from the tank by unthreading three bolts. There is no need to disconnect the syphon system or to remove the leak detector from the system to service the STP.
Manual Pressure Relief
As a standard FE PETRO® feature, a vent screw is provided to bleed line pressure to zero when necessary. By turning this screw, product is diverted back to the tank, dropping line pressure to zero. This reduces fuel discharged into the sump manhole or dispenser pan during servicing, further protecting service technicians and the environment.
