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.
Alternative Fuel ready with AG compatible hardware:
Specialized Design – compatible with Alternate Fuels Ethanol or Methanol concentrations up to 100% and MTBE, ETBE or TAME concentrations up to 20%.
Certified – UL79A and UL79B for use with renewable biofuels.
Superior motor design provides higher flow rates, lower power consumption, and increased safety and reliability:
Up to 5% Increased Flow – Improved stator and receptacle housing design provides larger fuel paths.
8% Less Power Consumption – More efficient motor design results in 8% reduction in wattage.
Better Quality – Red Jacket’s motor manufacturing yields improved quality, which means more station uptime than other STPs on the market.
Universal Compatibility – Fewer parts to stock.
Improved Reliability – Improved bearing design and upgraded insulation yield longer motor life.
Increased Safety – Maximum temperature remains ~125 degrees cooler vs. competitive models. Enhanced connectors separation meets latest flameproof standards.
Advanced packer manifold design expedites installation, simplifies service or testing, and sets the standard for Electrical and Environmental Safety:
Built-in Isolated Contractor’s Box – Electrical connection housing is built into the manifold and is completely isolated from the fuel path.
Easy to Install and Service – No adjustment required to fit yok, assembly is quick.
Increased Electrical Safety – Automatic electrical yoke disconnects upon removal of extractable bolts.
Environmentally Friendly – Automatic breaking of extractible seal upon bolt removal ensures automatic fuel drain back into tank, protecting the environment from contamination and site owners from related liability.
Innovative Check Valve Design – “Open” setting makes for easier line tests and servicing.
