    High Performance

    FE Petro’s two-stage centrifugal pump is coupled with a dependable Franklin Electric motor to provide higher heads, faster fuel delivery and lower cost operation. Motors are all three-phase for smooth operation and are available in various voltages. Units come standard with a 6" diameter riser pipe to mount the pump to the tank.

    Ease of Maintenance

    If service is required, FE Petro products are designed to put the operator back in business fast. Maintenance on the pump motor assembly can be performed without having an electrician on site. Large diameter pins and sockets provide automatic open circuits and disconnecting of the wiring when the extractable portion of the pump is removed. Properly spaced lifting eyes facilitate the removal of the unit without disturbing the discharge piping. The pump motor assembly is easily removed from the discharge head by removing four bolts and using standard pusher bolts. Replacement pump motor assemblies are available for comparably sized competitive pumps.


    Quality engineering and simplicity of design work to ensure years of reliable performance from every high capacity unit. The continuous duty, three-phase Franklin Electric motor with carbon bearings and stainless steel journals is FE Petro’s standard. The impellers, made of molded acetal, and diffusers of hard coated aluminum, with a stainless steel pump shaft, assure trouble-free operation in motor fuels. Dual (180º opposed) 3" horizontal discharge ports provide easy installation, and two built-in line check valves reduce installation costs. Two line pressure relief valves protect the dispensers, meters and piping from abnormal pressures due to thermal expansion. The mesh screen on the pump inlet prevents large particles from entering the unit and the unit is compatible with existing high capacity leak detector technology. New units are easily connected to field wiring without disassembly.


    Each and every high capacity pump is built to your tank and bury specifications and the complete assembly is performance tested to ensure that your needs are met. All high capacity pumps are UL listed and meet the requirements of UL 79.

    High Capacity Submersible Turbine Pump Model Designation System

    STP XXXXX Y - A - B

    A typical turbine model designation has up to five components to define the pump being supplied as follows:

    • STP = Basic Model Designation
    • XXXXX = Factory Installed Options
    • HCP model designations may include one or more of the following characters in alphabetical order:
    • AG = Alcohol-gasoline compatible (85% ethanol or 100% biodiesel capable)
    • Note: Standard models 0% to 10% ethanol capable
    • F = Floating suction adapter (3" NPT male adapter)
    • *R = Model R check valve (24 psi relief/22 psi reset for PLLD). *Note: If not otherwise specified, all HCP models supplied with standard model check valve (40 psi relief/35 psi reset for MLD and TS-LS300).
    • Y = Pump Motor Horsepower/Electrical Rating
    • 3 = 3 hp fixed speed, 208-230 VAC
    • 5 = 5 hp fixed speed, 208-230 VAC
    • 5H = 5 hp fixed speed, 460 VAC
    • 5G = 5 hp fixed speed, 575 VAC
    • A = Model Length
    • Model length is expressed as three numeric characters that indicate the length of the HCP from the turbine manifold bottom to the pump motor inlet in inches, available from 60" to 200" (additional charge for models 132" and longer).
    • B = Riser Pipe Length
    • Riser pipe length is expressed as two numeric characters that indicate the total length of the riser in inches. Riser pipes are available from 6" to 60" in three inch increments (additional charge and lead time for risers 33" or longer).
