Powder-coated and E-coated finishes protect exterior cast surfaces from accelerated corrosion.
Stainless steel fasteners, riser, variable length column pipe and coupler protect against corrosion and provide long service life.
UL and cUL listed.
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.
