As station size and volumes have continued to grow, more marketers are choosing variable speed to meet the high fuel throughput demands while gaining additional benefits only variable speed can offer.
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.
Variable speed systems deliver faster and more reliable flow rates than fixed speed systems resulting in higher throughput at virtually the same total cost of ownership.
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.
Variable speed 2 Hp pumps provide constant 10 gpm (38 lpm) for up to eight fueling positions operating simultaneously whil 4 Hp pumps 10 gpm (38 lpm) for up to 12 fueling position.
Hydraulic hammer is as a rapid 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 pump. Variable speed helps to minimize these effects and the wear it can cause on system components.
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.
The MagVFC™ variable frequency controller features a dual 7-segment display that displays running status and fault codes. A fault history on the controller also provides an enhanced troubleshooting process with faults like:
A fault history on the controller also provides an enhanced troubleshooting process with faults like these:
UL = Underload: Dry run or blocked PMA intake
LI = Low Incoming: Input power under voltage
LU = Locked Up: Overload at PMA startup
SC = Short Circuit: Short typically from controller to PMA
SU = Shorted Upper: Short typically in controller
OC = Open Circuit: Broken connection to PMA
Er = Extended Run: No power change for 60 minutes
HO = Hot Operation: Excessive controller temp / fan protection
Lr = Locked Rotor: Overloaded while PMA is running
With variable speed conversion kits you can convert your existing fixed speed pump to variable speed. As an affordable upgrade, the conversion requires a minimal investment as it works with your existing system to increase flow as more fueling points go live, delivering the flow you need, as you need it.
The all-in-one upgrade kits inculde a variable speed pump motor assembly, MagVFC™, and a four-wire contractor’s plug.
Variable speed upgrade kits are compatible with both FE PETRO® brand 4″ submersible turbine pumps as well as competitive pumps.
Easy installation, consisting of swapping out the pump motor and controller, as well as modifying the submersible length and wiring if applicable.
