The Red Jacket® Maxxum Submersible Turbine Pump (STP) is intended for 6” high flow applications and provides the industry’s highest flow rates. The Maxxum series boasts leading serviceability and safety features. With a 3 or 5 HP motor, it’s specifically engineered for high throughput applications such as truck stops, where extreme demand, multiple fuel points, and long piping runs reduce fuel flow to the nozzle.
The Maxxum (formerly Big Flo) STPs and unitized motor pumps (UMP) provide the industry’s highest flow rates by reducing the number of restrictions within the flow path. The efficient design also leads to less power consumption, contributing to a lower lifetime cost of operation. Easy access to valves and ports allows for reliable diagnostics and fast service.
Reduced Wear – enhanced design results in quieter operation and less wear
Improved Insulation Rating – higher insulation temperature rating assures longer running life
Increased Protection – additional stainless components result in better protection for use with blended fuels
Backwards Compatible – Maxxum UMPs are compatible with previous 3 & 5 HP Maxxum STPs
Explosion Proof – improved design provides increased levels of safety; certified UL/cUL/IECEx/ATEX Explosion proof motor.
Continuous Safety Improvements – design enhancements guided by newer international flame proofing standards.
