⅓ & ¾ Hp Pumps
⅓ & ¾ Hp Pumps
FE PETRO® ⅓ & ¾ Hp fixed speed submersible pumps deliver consistent flow rates for low throughput fuels.
WE SET THE STANDARD
FE PETRO® brand submersible pumping systems set the standard by which all other fuel pumping systems are measured. With best-in-class flow rates and backed by a long history of dependability, FE PETRO® pumps are responsible for delivering fuel to thousands of customers around the globe, day in and day out.
Advanced Protection
Stop corrosion in its tracks. Special powder-coated, e-coated, and stainless steel components defend your pump and the entire fuel system from accelerated corrosion.
Intake Filter Screen
Avoid system damage, pumping slowdowns, and reduce filter changes by keeping harmful tank debris, sediment, and corrosion from entering your pumping system.
Fuel Compatiblity
FE PETRO® pumps are UL listed with both UL79A (up to 85% ethanol) and UL79B (up to 20% or 100% Biodiesel).
Turbine Pump Interface
Remote enhanced pump monitoring and control including pump-in-water automation, clogged intake escalation, tank leveling, and tank priority.
Variable Length
Be prepared for whatever the jobsite throws at you. Our patented telescoping pump shafts let you adjust onsite for that perfect fit.
Available as an option on AG compatible submersible turbine pumps, Advanced Protection defends STPs from accelerated corrosion caused by the acedic byproduct of microbial activity.
Turbine Pump Interface is a powerful tool that creates a network between your FE PETRO® STP controllers and EVO™ Series ATGs. Through TPI, the tank gauge can be programmed to respond to faults in the submersible pumping system and react with intelligence that pump controllers alone cannot.
SEE TPI IN ACTIONPump In Water Automation
When the water level in a tank approaches the pump intake, the tank gauge will enter alarm mode and automatically shut down the pump, protecting the system and customer vehicles.
Leveling & Priority Modes
When managing two storage tanks of the same product ‘Leveling Mode’ can keep both tanks at the same percentage full without the use of a syphon bar between the two tanks.
Remote Pump Interaction
By networking the intelligent controllers to the fuel management system via TPI, a technician can remotely connect to the site to review the logged event history and view the status.
An Intake Filter Screen (IFS) provides fuel filtration for the entire system down to about the size of a grain of sand (0.009” openings). It’s designed to keep harmful debris, sediment, and tank corrosion from entering the pumping system and creating service events including dispenser filter changes.

Optional Features
Biofuel Blend Compatibility
FE PETRO® pumps are UL listed with both UL79A (up to 85% Ethanol) and UL79B (up to 20% or 100% Biodiesel).
Variable Length
The patented telescoping pump shaft lets installers adjust the length of the pump onsite for the perfect fit.
Advanced Protection
Stop corrosion in its tracks. Special powder-coated, e-coated, and stainless steel components defend your pump in the tank and in the sump from accelerated corrosion.
Turbine Pump Interface
Remote enhanced pump monitoring and control including pump-in-water automation, clogged intake escalation, tank leveling, and tank priority.
Intake Filter Screen
Avoid system damage, pumping slowdowns, and reduce filter changes by keeping harmful tank debris, sediment, and corrosion from entering the pumping system with this factory-installed option.
Standard Features
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.
Outlast, Outperform with Franklin Electric Inside
