VARIABLE SPEED
SUBMERSIBLE
TURBINE PUMPS
Maximise profits, minimise expenses. Introduced in 1995,
FE PETRO® brand variable speed submersible turbine pumps
(STPs) were the first of their kind for the petroleum industry.
With faster fill times during peak hours and power savings
during non-peak hours, FE PETRO® brand variable speed
STPs allow you to maximise profits while minimising operating expenses. Check out these benefits only FE PETRO®
brand variable speed STPs, the industry’s highest performing
4" diameter STPs, can provide.
HIGHLIGHTS
SPECIFICATIONS
•
Faster, more consistent flow rates than fixed speed
systems for higher throughput at virtually the same total
cost of ownership.
•
•
Variable speed models are available in variable lengths only.
•
Ramping up and down of pressure makes nozzles easier to
squeeze and helps reduce overall system wear.
•
Energy savings during non-peak business hours and
increased flow during peak hours.
•
Pressure relief valve: available in four pressure relief
settings, integral to check valve. Standard model relieves
at 2.76 bar and resets above 2.41 bar.
•
Potential for reduced energy costs without sacrificing a
faster customer fuelling experience and without a
transducer or special wiring.
•
Syphon: venturi-type syphon primer supplied with every
submersible. Syphon check valve and secondary syphon
sold separately.
•
Energy savings during non-peak business hours and
increased flow during peak hours.
•
Air eliminator: every submersible includes a tank return path with
one-way check valve to provide active air elimination.
•
Potential for reduced energy costs without sacrificing a
faster customer fuelling experience and without a
transducer or special wiring.
•
Electrical disconnect: electrical yoke for positive contractor
disconnect during service.
•
A variable speed STP will ramp up and down to provide only
the pressure needed to meet demand and significantly
minimise the effects of hydraulic hammer.
•
Control is determined through the PMA power
consumption, eliminating the need for a transducer or
special wiring.
Pump Motor
• 2 Hp or 4 Hp, variable speed, two-stage centrifugal type
pump motor with integral, automatic, thermal overload
protection.
•
Setup selections include 2 Hp or 4 Hp, MLD or PLLD,
gas or diesel, and Master-Slave, alternating circuit
manifolded pump control options.
•
STP variable speed models are listed for fuel mixtures
containing up to 10% ethanol, and 20% MTBE, 20% ETBE
or 17% TAME with gasoline.
•
IST® variable speed models are 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.
•
•
All variable speed (non-AG) 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 nongelled pourable state.
All wetted elastomers are made of a high grade,
fluorocarbon compound.
•
Max. pressure: selectable operating pressure on MagVFC™ or
EcoVFC™ between 1.65 bar and 2.9 bar deadhead.
•
Available with MagShell® which results in 45% increased
flow area around motor.
Power Requirements
Variable speed pumps can only be controlled by a
MagVFC™ or EcoVFC™ variable frequency controller:
•
•
VS2 models can operate with single-phase incoming
power supply to the MagVFC™.
•
VS2 and VS4 models can operate with three-phase
incoming power supply to the EcoVFC™.
•
Incoming power supply is 200-250 VAC, 50 Hz for the
MagVFC™ and 360-440 VAC, 50 Hz for the EcoVFC™.
•
MagVFC™ and EcoVFC™ output a three-phase, variable
frequency signal, valid for FE PETRO® variable speed
pumps only.
•
•
•
VS2 max. motor draw: 9 Amps.
SUBMERSIBLE
PUMPING SYSTEMS
Liquid Compatibility
• Max. liquid viscosity: 70 SSU at 60 °F (15 °C).
Check valve: 70 mm diameter fluorocarbon seal
constructed with cast aluminium body and steel
backing washer.
VS4 max. motor draw: 15 Amps.
MagVFC™ or EcoVFC™ max. line draw: 20 Amps.
