Power Requirements
IST models can only be powered by a VFC™ 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.
Pump Motor
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.
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% ethanol with gasoline, and 20% MTBE, 20% ETBE or 17% TAME with gasoline.
IST models can also be used for fuel mixtures containing up to 5% biodiesel, 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.
