Why More Operators are Choosing Variable Speed Pumping_Blog_Header_1600px (1).jpg

The Benefits of Variable Speed

May 19, 2026

Variable speed submersible pumping systems adjust pump motor speed in real time to match demand at each fueling point. That responsiveness delivers faster fill times during peak hours, lower energy consumption when demand is light, and consistent flow rates that reduce wait times at the dispenser. By avoiding the sudden pressure spikes that occur when flow stops abruptly, variable speed operation also reduces mechanical stress on equipment over time.

Since bringing variable speed pumping to the service station industry in 1996, Franklin Electric has provided customers with consistent fueling experiences and improved uptime. The Guardian Series™ Variable Frequency Pump Controller brings advanced performance and efficiency to fueling operations. Designed to optimize flow rates, this intelligent controller adjusts pump motor speeds in real time to maintain consistent fuel flow, even during peak demand.

THE BENEFITS OF VARIABLE SPEED

Faster, Smarter Fueling
With faster fill times during peak hours and power savings during non-peak hours, 2 Hp and 4 Hp variable speed submersible pumping systems allow operators to maximize profits while mitigating operating expenses.

Consistent Customer Experience
Variable speed ensures consistent flow rates, even during peak demand, providing customers with faster fueling and a smoother experience at the dispenser, reducing wait times and improving overall satisfaction.

Increased Uptime
Advanced user interface features, combined with remote connectivity via Turbine Pump Interface™, enable rapid event detection and automated pump responses, minimizing downtime and ensuring swift site recovery to maintain uninterrupted fuel flow.

Prevent Equipment Wear
Minimize sudden pressure spikes, known as hydraulic hammer, that occur during sudden stoppages in flow. These spikes can be exaggerated in fixed speed systems and lead to accelerated equipment wear and damage.

FILLING CARS FASTER & SMARTER

Variable speed pumping systems, powered by Guardian Series™ Variable Frequency Controllers, ramp up the system's horsepower as needed to provide optimal flow rates at fueling points. The result is faster and more consistent flow rates at peak business times compared to fixed speed systems.

By incorporating features such as precise flow control, fault diagnostics, and protective mechanisms, the Variable Frequency Controller enhances operational performance, reduces maintenance costs, and extends equipment lifespan.
