FPS FX Programmable Fuel Maintenance System – 2.5 GPM Fuel Polishing

The FPS FX is a fully automated, programmable fuel maintenance system designed to remove water, sludge, and particulate contamination from diesel and bio-fuel storage tanks. With a nominal flow rate of 2.5 GPM, this compact unit offers continuous-duty filtration for critical power applications. Its intelligent controller allows for unattended operation, making it a reliable solution for ensuring fuel quality in generator enclosures, engine rooms, and other confined spaces.

The FPS FX fuel maintenance system is an automated filtration solution engineered to stabilize diesel and bio-fuels by eliminating water, sludge, and microbial contamination. Unlike portable transfer pumps, this system is designed for permanent indoor installation, operating independently to perform routine fuel polishing without manual intervention. Whether installed inside a generator set enclosure or a marine engine room, the FPS FX continuously circulates and cleans stored fuel, preventing the growth of "diesel bug" and reducing the risk of filter clogs. By maintaining ISO-clean fuel standards, this compact fuel maintenance system dramatically extends the life of downstream components and guarantees fuel reliability for standby generators, data centers, and industrial operations.

Key Features

The FPS FX is purpose-engineered for facilities requiring autonomous diesel polishing within tight spaces. Its hardware combination—a Smart Filtration Controller, continuous-duty DC gear pump, centrifugal water separator, and LG-X 500 magnetic conditioner—delivers a robust system for maintaining bulk fuel quality. The programmable automation reduces manual oversight while the integrated alarm system ensures operators are alerted to leaks, clogs, or water accumulation.

Smart Filtration Controller with Full Automation: Equipped with a programmable digital timer, the system allows users to schedule up to eight ON/OFF cycles per week. The controller retains memory during power outages and provides clear visual alarm indicators for service needs, ensuring the system performs its duties without constant supervision.
Continuous-Duty Gear Pump with Viton Seals: The heart of the FPS FX is a robust DC gear pump rated for sustained operation. Viton seals are used throughout to resist degradation from diesel, bio-fuel blends, and chemical additives, ensuring leak-free performance and long-term reliability in demanding environments.
Centrifugal Water Separator & 3-Stage Filtration: Fuel first passes through a centrifugal water separator that spins out bulk water and heavy solids, followed by a high-efficiency particulate filter. Options range from a back-flushable 30µ element to a reusable 60µ stainless steel screen, removing microscopic rust, dirt, and sludge from the fuel stream.
LG-X 500 Inline Magnetic Fuel Conditioner: This passive, maintenance-free device subjects the fuel to a powerful magnetic field. The process helps de-cluster paraffin and asphaltene molecules, improving fuel stability and reducing the surface tension of water droplets for more efficient separation during the filtration cycle.
Comprehensive Safety & Alarm Suite: Integrated sensors provide fail-safe protection and operational awareness. The system features automatic pump shutdown upon detection of a fuel leak, high vacuum indicating a clogged filter, or excessive water accumulation in the sump. Alarms must be manually reset, ensuring personnel are notified of any service requirements.
Compact, Space-Saving Wall Mount Design: Sized at just 20" x 17" x 7" (HxWxD), the FPS FX mounts directly to a wall inside tight mechanical rooms. The powder-coated aluminum backplate supports all components—including the pump, controller, and filter housing—providing a rugged, self-contained unit that requires minimal floor space.

Applications

Standby Generator Set Enclosures: Long idle periods allow water condensation and sludge to accumulate in generator tanks. The FPS FX installs inside the generator housing to run automated polishing cycles, ensuring the engine receives clean fuel during a power outage.
Marine Engine Rooms: Vessels operating in high-humidity environments are prone to water ingress in fuel tanks. This system connects to 12/24VDC ship power, removing emulsified water and biological growth to prevent engine stalling and filter blockages at sea.
Data Center Fuel Storage: Facilities with backup generators require guaranteed fuel readiness 24/7. The programmable controller allows operations teams to schedule fuel turnovers during low-load periods, eliminating the "dead storage" that leads to fuel degradation.
Off-Grid Power Generation: Remote telecom towers and mining sites often have limited maintenance access. The FPS FX automates fuel maintenance between service visits, with alarm outputs that can be relayed to central monitoring systems for early warning.
Industrial & Agricultural Fuel Reserves: Manufacturing plants and farms storing large volumes of diesel for heavy equipment can use this system to polish fuel at the point of storage, reducing the costs associated with fuel polishing services and unexpected downtime.

The 10µ filter provides the highest level of particulate removal, ideal for critical engines. The 30µ filter is the standard-issue element for general polishing. The 60µ stainless steel screen is a reusable, back-flushable option for environments with heavy debris loads.

No. The system is strictly designed for diesel and bio-fuel blends with a flash point of 100°F (37.8°C) or higher. Using it with gasoline presents an immediate explosion and fire hazard.

The system is designed for low-voltage DC applications, operating on either 12VDC (10A) or 24VDC (5A). This makes it suitable for integration with generator control panels and vessel electrical systems.

The Smart Filtration Controller features a "High Vacuum" alarm. When the filter becomes clogged and the suction vacuum reaches 12" HG, the pump will automatically shut off and the alarm indicator will light up, signaling that the element requires back-flushing or replacement.

The LG-X 500 is a passive device that applies a magnetic field to the fuel. This process helps de-cluster microscopic contaminants and improves the fuel's ability to separate from water, enhancing overall polishing efficiency.

The FPS FX is intended exclusively for permanent indoor installation — it is not rated for outdoor or exposed environments. It should be wall-mounted on a hard, level surface inside a well-ventilated space with ambient temperature between 41 and 104°F (5 to 40°C). Its compact dimensions make it ideal for generator enclosures, marine engine rooms, and plant utility rooms.
