SUBMERSIBLE
PUMPING SYSTEMS
MAGVFC™ VARIABLE
FREQUENCY CONTROLLER
Introduced in 1995, FE PETRO® brand variable speed
submersible turbine pumps (STPs) were the first of their kind
for the petroleum equipment industry. With faster fill times
during peak hours and power savings during non-peak hours,
FE PETRO® brand variable speed STPs allow you to maximize
profits while minimizing operating expense. These benefits are
something only FE PETRO® brand variable speed STPs, the
industry’s highest performing 4" diameter STPs, can provide.
HIGHLIGHTS
Higher Flow Rates
Minimize Hydraulic Hammer
Variable speed systems ramp up the system’s horsepower
as needed to provide optimal flow rates at fueling points.
This results in faster and more consistent flow rates at
peak business times compared to fixed speed systems.
Benefits include:
Hydraulic hammer is defined as a sudden pressure spike that
is the result of a sudden stoppage in flow in a pressurized
piping system. Hydraulic hammer can be exaggerated in a
system that utilizes a high pressure fixed speed STP.
• Faster and more reliable flow rates than fixed speed
systems resulting in higher throughput at virtually the
same total cost of ownership.
• Ramps pressure up and down making nozzles easier to
squeeze for consistent customer user experience.
• Ramping up and down reduces system wear from line
shock, promoting a longer overall system lifetime.
Efficient Energy Consumption
Because a variable speed system is constantly providing only
the necessary horsepower to achieve desired flow rates, the
system only consumes as much energy as is needed.
Benefits include:
• Energy savings during non-peak business hours and
increased flow during peak hours.
• Potential for reduced energy costs without sacrificing a
faster customer refueling experience.
• A fixed speed pumping system is incapable of changing the
flow rate dependent upon demand and as a result, hydraulic
hammer is likely to result when flow is interrupted.
• Hydraulic hammer may result in system fatigue and
intensified wear to system components such as diaphragm
valves in multi-product dispensers, leak detectors or
hanging hardware.
• A variable speed STP will ramp up and down to provide only
the pressure required to meet demand, significantly
minimizing the effects of hydraulic hammer.
Meet Your Flow Rate Needs
The STP can be adjusted at installation to perform at a
maximum per-nozzle flow rate of 10 gpm (38 lpm) based
on the specifications of your piping and dispensing system.
• Depending on peak business requirements, choose from
either 2 hp or 4 hp variable speed models to meet your
desired flow rates.
• 2 hp pumps provide constant 10 gpm (38 lpm) for up
to 8 fueling positions operating simultaneously.
• 4 hp pumps provide constant 10 gpm (38 lpm) for up
to 12 fueling positions operating simultaneously.
