Variable speed pumps are controlled by the MagVFC™ variable frequency controller which provides control for both 2 Hp and 4 Hp variable speed submersible turbine pumps.
FILL CARS VASTER WITH VARIABLE SPEED
As station size and volumes have continued to grow, more markters are choosing variable speed to meet the high fuel throughput demands while gaining additional benefits only variable speed can offer.
Variable speed systems ramp up the system’s horsepower as needed to provide optimal flow rates at fueling points. This results in faster and more consistent flow rates at peak business times compared to fixed speed systems.
Variable speed systems deliver faster and more reliable flow rates than fixed speed systems resulting in higher throughput at virtually the same total cost of ownership.
Meet Your Needs
The STP can be adjusted at installation to perform at a maximum per-nozzle flow rate of 10 gpm (38 lpm) based on the specifications of your piping and dispensing system.
2 Hp or 4 Hp
Variable speed 2 Hp pumps provide constant 10 gpm (38 lpm) for up to eight fueling positions operating simultaneously whil 4 Hp pumps 10 gpm (38 lpm) for up to 12 fueling position.
Hydraulic hammer is as a rapid pressure spike that is the result of a sudden stoppage in flow in a pressurized piping system. Hydraulic hammer can be exaggerated in a system that utilizes a high pressure fixed speed pump. Variable speed helps to minimize these effects and the wear it can cause on system components.
A fixed speed pumping system is incapable of changing the flow rate dependent upon demand and as a result, hydraulic hammer is likely to result when flow is interrupted.
Hydraulic hammer may result in system fatigue and intensified wear to system components such as diaphragm valves in multi-product dispensers, leak detectors or hanging hardware.
Minimize The Effects
A variable speed STP will ramp up and down to provide only the pressure required to meet demand, significantly minimizing the effects of hydraulic hammer.
The MagVFC™ variable frequency controller features a dual 7-segment display that displays running status and fault codes. A fault history on the controller also provides an enhanced troubleshooting process with faults like:

With variable speed conversion kits you can convert your existing fixed speed pump to variable speed. As an affordable upgrade, the conversion requires a minimal investment as it works with your existing system to increase flow as more fueling points go live, delivering the flow you need, as you need it.
In the Kit
The all-in-one upgrade kits inculde a variable speed pump motor assembly, MagVFC™, and a four-wire contractor’s plug.
Variable speed upgrade kits are compatible with both FE PETRO® brand 4" submersible turbine pumps as well as competitive pumps.
Easy installation, consisting of swapping out the pump motor and controller, as well as modifying the submersible length and wiring if applicable.
- Variable speed models are available in variable lengths only.
- Check valve: 2¾" diameter fluorocarbon seal constructed with cast aluminum body and steel backing washer.
- Pressure relief valve: available in four pressure relief settings, integral to check valve. Standard model relieves at 40 psi and resets above 35 psi.
- Syphon: venturi-type syphon primer supplied with every submersible. Syphon check valve and secondary syphon sold separately.
- Air eliminator: every submersible includes a tank return path with one-way check valve to provide active air elimination.
- Electrical disconnect: electrical yoke for positive contractor disconnect during service.
- 2 hp or 4 hp, variable speed, two-stage centrifugal type pump motor with integral, automatic, thermal overload protection.
- Max. flow: 2 hp = 110 gpm, 4 hp = 140 gpm.
- Max. pressure: selectable operating pressure on MagVFC™ between 24 psi and 42 psi deadhead.
- Available with MagShell™, which results in 45% increased flow area around motor.
Power Requirements - 60Hz & 50Hz
IST models can only be powered by a MagVFC™ controller:
- 2 hp models can operate with single phase incoming power supply to the MagVFC™.
- 2 hp and 4 hp models operate with three-phase incoming power supply to the EcoVFC™.
- Incoming power supply to the MagVFC™ can be 200-250 VAC, 50 Hz and 360-440 VAC, 50 Hz for the EcoVFC™.
- MagVFC™ outputs a three-phase, variable frequency signal, valid for FE Petro variable speed pumps only.
- 2 hp max. motor draw: 9 Amps.
- 4 hp max. motor draw: 15 Amps.
- MagVFC™ max. line draw: 20 Amps.
- Max. liquid viscosity: 70 SSU at 60 °F (15 °C).
- IST models imply alcohol-gasoline compatibility for fuel mixtures containing up to 85% ethanol, and 20% MTBE, 20% ETBE or 17% TAME with gasoline.
- IST models can also be used with diesel fuels, fuel oils, kerosene, Avgas and jet fuels in a non-gelled pourable state.
- All wetted elastomers are made of a high grade, fluorocarbon compound.
- Consult factory for applicable approvals.
- Franklin Fueling Systems is an ISO 9001 Certified Manufacturer.
Variable Speed Submersible Turbine Pump Model Designation System
XXX YYYYY Z - A - B
A typical turbine model designation has up to five components to define the pump being supplied as follows.
- XXX = Basic Model Designation
- STP = These standard variable speed and variable length models are capable of up to 10% ethanol with gasoline
- IST** = These variable speed and variable length models include alcohol-gasoline compatibility (up to 85% ethanol, up to 20% biodiesel, or 100% biodiesel).
- YYYYY = Factory Installed Options
- Model designations may include one or more of the following characters in alphabetical order:
- F = Floating suction adapter (1½" NPT female adapter)
- K = Intake filter screen (IFS, factory installed to PMA)
- M = MagShell™ (flow enhancing, expanded PMA shell)
- R* = Model R check valve (24 psi relief/22 psi reset for PLLD)
- W* = Model W check valve (16 psi relief/13 psi reset for PPM4000)
- Z = Pump Motor Horsepower Rating
- VS2** = 2 Hp variable speed
- VS4 = 4 Hp variable speed
- A = Model Length (see table below)
- VL1 = STP variable length range #1
- VL2 = STP variable length range #2
- VL3 = STP variable length range #3
- B = Riser Pipe Length (see diagram above)
- Riser pipe length is expressed as two numeric characters that indicate the total length of the riser in inches. Riser pipes are available from 7" to 69" in 1" increments (additional charge for risers 31" or longer).
*If not otherwise specified, all models are supplied with standard model check valve (40 psi relief /35 psi reset for MLD, TS-LS300, and TS-LS500).
**If not otherwise specified, 2 Hp variable speed pump motor horsepower rating is implied for IST models.
