4HP Variable Speed STP AG Seals

Pumps & Dispensers

Dry tank (initiates an immediate pump shut-down). Continuous pump run. Low incoming voltage. Pump motor failure. Short circuit detection. Controller faults. Open circuit detection.

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. Approvals Consult factory for applicable approvals. Quality Certification Franklin Fueling Systems is an ISO 9001 Certified Manufacturer.
