Enhance fuel station efficiency with the ECO VFC™ Variable Speed Controller, engineered for 50Hz 3-phase submersible turbine pumps. Designed to meet the increasing demand for higher fuel throughput, the ECO VFC™ optimizes pump performance by adjusting motor speed in real time, delivering consistent flow rates while reducing energy consumption and system wear.
Unlike fixed-speed systems, the ECO VFC™ ramps the pump’s horsepower up or down as needed, minimizing hydraulic hammer, extending equipment life, and reducing operational costs. Whether during peak hours or off-peak periods, this intelligent controller ensures optimal performance and fuel dispensing efficiency.
Consistent and Faster Flow Rates
The ECO VFC™ continuously adjusts pump speed, ensuring optimal flow rates across all fueling positions, reducing wait times and improving customer experience.
Minimized Hydraulic Hammer
Unlike fixed-speed pumps that can cause sudden pressure spikes, the ECO VFC™ dynamically adjusts pressure to prevent wear on pipes, valves, and other critical components.
Energy Savings
By delivering only the necessary power for each fueling session, the ECO VFC™ reduces electricity consumption, cutting operational costs during off-peak hours.
Advanced Fault Detection
Built-in diagnostics display fault codes such as underload, low voltage, short circuits, and overheating, allowing for quick maintenance and minimal downtime.
Upgrade Existing Pumps
Easily convert fixed-speed pumps to variable speed with ECO VFC™ upgrade kits, which include a new pump motor assembly, controller, and a four-wire contractor’s plug.

2 hp and 4 hp models operate with three-phase incoming power supply to the EcoVFC™.
Incoming power supply is 360-440 VAC, 50 Hz or 60 Hz for the EcoVFC™.
EcoVFC™ outputs a three-phase, variable frequency signal, valid for FE Petro variable speed pumps only.
2 hp (1.5 kW) max. motor draw: 9 Amps.
4 hp (3 kW) max. motor draw: 15 Amps.
EcoVFC™ max. line draw: 20 Amps.
Pump Motor
2 h or 4 hp, variable speed, two-stage centrifugal type pump motor with integral, automatic, thermal overload protection.
Max. flow: 2 hp = 110 gal/min (379 L/min), 4 hp = 140 gal/min (530 L/min).
Max. pressure: selectable operating pressure on EcoVFC™ between 24 psi (1,65 bar) and 42 psi (2,90 bar) deadhead.
Available with MagShell™, which results in 45% increased flow area around motor.
Liquid Compatibility
Max. liquid viscosity: 70 SSU at 60 °F (15 °C).
IST models imply alcohol-gasoline compatibility for fuel mixtures containing diesel fuel with up to 20% biodiesel, 100% biodiesel, up to 85% ethenol with gasoline, 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.
Standard Features
All IST models include variable speed, variable length options and alcohol-gasoline compatibility.
Check valve: 70mm diameter fluorocarbon seal constructed on 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 tank return path with one-way check valve to provide active air elimination.
Electrical disconnect: electrical yoke for positive contractor disconnect during service.
