Can the FPS LX-F be used with fuels other than diesel?

The system is specifically engineered for diesel and bio-fuel blends with a flash point of 100°F (37.8°C) or higher. It is not certified for use with gasoline, petrol, or other highly flammable liquids due to significant safety risks.

What are the key upgrade options available?

Upgrade options include an Automatic Water Drain (AWD) for continuous water removal, a manual additive injection port, multi-tank polishing capability using motor-operated valves (MOVs), and a multi-point flow path system for enhanced tank cleaning coverage.

Does the pump need to be primed before operation?

Yes, the pump supplied with the FPS LX-F is NOT self-priming and must not be run dry. The system and all suction plumbing must be completely filled with fuel to wet the pump gears and achieve rated performance. A priming tee is recommended to facilitate this.

What is the purpose of the LG-X 3000 magnetic conditioner?

The LG-X 3000 is a passive, in-line device that applies a powerful magnetic field to the fuel stream. This process helps break down molecular clusters of paraffin and asphaltenes (diesel bug precursors), which improves fuel stability and reduces the surface tension of entrained water for more efficient separation.

Leak + Vacuum Alarm Auto Safety Shutdown

The FPS LX-F compact fuel maintenance system is engineered for total automation. Once installed and programmed, it operates independently, performing routine fuel polishing cycles to stabilize diesel and bio-fuels. By eliminating free water, microbial contamination (diesel bug), and solid particulates, the system extends equipment life and guarantees fuel readiness for mission-critical applications. Its open backplate design integrates a rugged 3/4 HP spur gear pump, a centrifugal water separator, and a Smart Filtration Controller. This combination allows for precise scheduling and provides immediate alerts for high vacuum, high water, or leak detection, ensuring your fuel remains clean, clear, and reliable between service intervals.

Key Features

The FPS LX-F is purpose-engineered for facilities requiring autonomous diesel polishing with a high flow rate. Its hardware combination—a Smart Filtration Controller, continuous-duty 3/4 HP spur gear pump, centrifugal water separator, and LG-X 3000 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: The system features a programmable controller that allows operators to schedule up to three ON/OFF cycles per day for each day of the week. This fully autonomous operation ensures fuel is polished routinely without manual intervention, while the intuitive user interface and external monitoring integration provide complete status awareness.
Continuous-Duty 3/4 HP Gear Pump: At the heart of the FPS LX-F is a heavy-duty spur gear pump with Viton seals, rated for continuous operation. This pump delivers a nominal flow rate of 10 GPM (38 LPM), capable of polishing up to 4,800 gallons in an 8-hour shift. Viton seals provide superior chemical resistance, ensuring long-term reliability with diesel, bio-fuels, and fuel additives.
Multi-Stage Filtration System: Fuel is cleaned in two distinct stages. The primary stage uses a centrifugal water separator and a filter cartridge (10µ, 30µ, or 60µ stainless steel screen) to spin out bulk free water and remove large solid contaminants. The secondary stage utilizes a spin-on fine filter (3µ, 10µ, or 25µ) to capture microscopic particulates, delivering polished, ISO-clean fuel back to the tank.
LG-X 3000 Inline Magnetic Fuel Conditioner: This passive, maintenance-free unit applies a powerful magnetic field to the fuel stream before it enters the primary filter. The process helps break down and de-cluster paraffin and asphaltene molecules, which improves fuel stability and reduces the surface tension of water droplets, making them easier to separate and remove.
Comprehensive Safety & Alarm Suite: The system features an automatic pump shut-down for critical safety events. Integrated sensors include a leak detection float switch in the drip tray, a high vacuum switch (factory set at 16" Hg) to indicate a clogged supply, a pressure switch (factory set at 22 PSI) to indicate a blocked discharge, and a water detection sensor to alert when the sump needs draining.
Compact, Space-Saving Design: Sized at approximately 26" x 34" x 12", the FPS LX-F is designed for installation in confined spaces. Its powder-coated aluminum backplate allows for direct wall mounting inside generator set enclosures, engine rooms, or mechanical closets, making it an exceptional choice where floor space is at a premium.

Applications

Standby Generator Set Enclosures: Long idle periods lead to water condensation and sludge accumulation. The FPS LX-F installs directly inside the generator housing, running automated polishing cycles to ensure the engine receives clean fuel the moment a power outage occurs.
Marine Engine Rooms: Vessels in high-humidity environments are highly susceptible to water ingress and microbial growth. This system connects to shipboard AC power, continuously removing emulsified water and biological contamination to prevent engine stalling and filter blockages at sea.
Data Center Fuel Storage: Facilities that house backup generators require guaranteed fuel readiness 24/7/365. The programmable controller allows operations teams to schedule fuel turnovers during low-load periods, eliminating the "dead storage" problem that leads to fuel degradation and system failure.
Industrial Fuel Reserves: Manufacturing plants and mining sites storing large volumes of diesel for heavy equipment can use the FPS LX-F to polish fuel at the point of storage. This proactive maintenance approach significantly reduces the costs associated with emergency fuel replacement and unscheduled downtime.
Remote & Off-Grid Power Generation: Remote telecom towers and critical infrastructure sites often have limited maintenance access. The FPS LX-F automates fuel maintenance between service visits, with alarm outputs that can be relayed to central monitoring systems for early warning of potential issues.

The FPS LX-F's 10 GPM flow rate makes it well-suited for maintaining fuel quality in bulk storage tanks up to approximately 20,000 gallons. For larger tanks or applications requiring faster turnaround, please consult our engineering team for a tailored analysis.

The primary filter combines a centrifugal water separator and a coarse filter to spin out bulk water and large sludge particles. The secondary filter is a fine filter that polishes the fuel after it leaves the pump, capturing microscopic contaminants to ensure the fuel is exceptionally clean before it returns to the tank.

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 the system with gasoline or other highly flammable liquids presents a serious risk of explosion and fire.

The system supports several upgrade options, including an automatic water drain (AWD) to automatically remove collected water, a manual additive injection port for fuel dosing, multi-tank polishing capability using motor-operated valves, and a multi-point flow path for better tank cleaning coverage. A controller upgrade may be required for certain combinations.

When primed, the system is capable of a vertical lift of 15 feet or a horizontal run of 100 feet of plumbing using the minimum recommended piping size with no additional restrictions. Any combination of vertical and horizontal runs will reduce the suction capability proportionally.

Regular maintenance includes checking and replacing the primary and secondary filter elements, draining collected water from the water separator, and inspecting the LG-X 3000 fuel conditioner for debris. The system's smart controller provides visual alarms to indicate when service is needed, such as a high vacuum alarm signaling a clogged filter.
