UL Catalog 2022-2023 - Flipbook - Page 29
SPECIFICATIONS
General
• Variable speed models are available in variable lengths only.
Power Requirements
• Variable speed pumps can only be controlled by a MagVFC™
variable frequency controller.
• 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.
SUBMERSIBLE
PUMPING SYSTEMS
• VS4 models require three-phase incoming power supply to
the MagVFC™ for proper operation.
• Incoming power supply to the MagVFC™ can be 200-250 VAC,
50 or 60 Hz.
• Syphon: venturi-type syphon primer supplied with every
submersible. Syphon check valve and secondary syphon sold
separately.
• MagVFC™ outputs a three-phase, variable frequency signal,
valid for FE PETRO® variable speed pumps only.
• Air eliminator: every submersible includes a tank return path
with one-way check valve to provide active air elimination.
• Max motor draw: 15 Amps.
• MagVFC™ max. line draw: 20 Amps.
• Electrical disconnect: electrical yoke for positive contractor
disconnect during service.
Liquid Compatibility
• Max. liquid viscosity: 70 SSU at 60 °F (15 °C).
Pump Motor
• 4 Hp, variable speed, two-stage centrifugal type pump motor
with integral, automatic, thermal overload protection.
• STP variable speed models are UL listed for fuel mixtures
containing up to 10% ethanol, and 20% MTBE, 20% ETBE or
17% TAME with gasoline.
• IST/ISTAP variable speed models are UL and cUL listed 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.
• 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.
• All variable speed models can also be used with diesel fuels,
fuel oils, kerosene, Avgas and jet fuels in a non-gelled
pourable state.
Approvals
• cULus listed.
• All wetted elastomers are made of a high grade,
fluorocarbon compound.
• Consult factory for applicable approvals.
