The MTC-3000 mobile fuel polishing system is a high-capacity, cart-mounted, AC-powered industrial unit engineered to eliminate water, sludge, ferrous metals, microbial contamination, and fine particulate from diesel and bio-fuel storage tanks. Delivering a nominal flow rate of 26 GPM / 1,560 GPH, the system processes fuel through a three-stage cleaning circuit comprising a mechanical water separator, an LG-X 3000 inline magnetic conditioner, and a secondary spin-on fine filter selectable from 1, 3, 10, or 25 microns — including water block options. Its cart-based design with locking 1.5-inch cam and groove inlet connections, 25-foot hoses, and a built-in spill containment tray makes it a fully self-contained polishing unit capable of servicing high-volume tanks and multiple locations across a site in a single maintenance session.
The MTC-3000 is a heavy-duty mobile fuel polishing system built for facilities and operations that maintain large-volume diesel fuel stores where contamination control directly affects equipment reliability and operational uptime. Powered from a standard AC mains outlet and mounted on a wheeled cart for unrestricted site mobility, the system draws fuel through a staged cleaning circuit — a mechanical water separator for bulk water and sludge removal, an LG-X 3000 inline magnetic conditioner for ferrous metal capture, and a precision-rated spin-on fine filter to deliver fuel that meets modern diesel engine cleanliness requirements. With a 26 GPM / 1,560 GPH flow rate, the MTC-3000 can process over 12,400 gallons in a standard eight-hour maintenance window, making it the right choice for high-capacity marine fuel tanks, industrial bulk storage, large generator installations, and commercial fleet fuel depots. Its fine filter bypass mode, locking cam and groove connections, and integrated spill containment tray are all engineered for demanding, real-world fuel maintenance work where efficiency and safety cannot be compromised.

Setting up the MTC-3000 begins with connecting the system to a compatible AC mains power supply — either 120V/60Hz or 230V/50Hz — and ensuring the unit is properly grounded for operator safety. The 1.5-inch clear suction hose is attached to the inlet cam and groove port and positioned so its end reaches the deepest accessible point within the fuel storage tank, targeting the area where water and sludge naturally settle. The 1.25-inch discharge hose is connected to the appropriate outlet port depending on the selected operating mode. Before starting the pump, the entire suction side of the system — including the suction hose, primary water separator housing, internal plumbing, and pump — must be fully primed with fuel. The pump is not self-priming and running it without fuel in the circuit will cause damage.
For tanks carrying significant contamination, a three-phase polishing approach is recommended. In Phase 1, the system operates in bypass mode with the discharge hose routed to a separate waste container, allowing bulk free water and bottom sludge to be pumped out and discarded without recirculating contamination back into the tank. In Phase 2, still in bypass mode, the discharge hose is placed back into the tank and fuel is recirculated through the mechanical water separator — progressively removing residual water, sludge, and large particulate while keeping the fine filter out of the circuit and extending its service life. The vacuum gauge monitors suction-side condition throughout both bypass phases, alerting the operator if the water separator builds restriction and needs draining via its dedicated drain valve.
Phase 3 transitions the MTC-3000 to fine filtration mode by moving the discharge hose connection to the second outlet port, routing fuel through the absolute-rated spin-on fine filter after the separator and magnetic conditioning stages. The pressure gauge between the pump outlet and the fine filter housing monitors element condition in real time — when pressure climbs to 20–25 PSI or the needle enters the red zone, the filter element is saturated and should be replaced before resuming the session. Once polishing is complete and clean fuel samples confirm acceptable cleanliness, the pump is shut down, the system is drained for storage, and the spill containment tray captures any residual fuel released during hose disconnection or filter servicing.
The MTC-3000 is designed for use with diesel fuel and bio-diesel blends that have a flash point at or above 100°F (37.8°C). It must not be used with gasoline, petrol, or any other flammable liquid below this flash point threshold — operating the system with such fluids creates an immediate fire and explosion hazard. Always confirm the flash point of the fuel before connecting and running the system, particularly when working with unfamiliar bio-blend formulations or fuel drawn from mixed-use storage tanks.
The MTC-3000 operates at a nominal flow rate of 26 GPM (1,560 GPH / 98.4 LPM). This translates to approximately 12,480 gallons (47,242 litres) in an 8-hour maintenance shift and up to 37,440 gallons (141,726 litres) over a 24-hour continuous run — making it well suited for high-volume tank servicing where lower-capacity polishing units would require impractically long operating times. When running on a 50 Hz supply, the flow rate reduces to 20.8 GPM / 1,248 GPH.
Fine filter cartridges (available in 1µ, 3µ, 10µ, and 25µ absolute ratings) remove particulate contamination down to their rated micron size and are the correct choice for tanks where particulate is the primary concern. Water block filters (3µ WB-3 and 10µ WB-10) combine the same particulate removal performance with hydrophobic filter media that actively prevents both free and emulsified water from passing downstream. For tanks with combined water and particulate contamination, the recommended approach is to begin polishing with a coarser particulate filter to handle bulk contamination across early passes, then switch to a 3µ water block cartridge for the final fine filtration phase to achieve the highest attainable fuel cleanliness standard.
Engaging bypass mode during the initial polishing phases removes bulk free water, heavy sludge, and coarse particulate through the mechanical water separator alone — without routing that contamination through the secondary fine filter cartridge. Fine filter elements are absolute-rated consumables: asking them to capture heavy bulk contamination dramatically shortens their service life and increases the cost and frequency of element changes required to complete a polishing cycle on a badly fouled tank. The phased approach — bypass mode for Phases 1 and 2, fine filtration mode for Phase 3 — maximises filter element life, lowers per-tank operating cost, and ensures that the high-efficiency final filtration stage is only applied once the fuel has already been substantially cleaned by the separator and magnetic conditioning stages.
The MTC-3000 operates on either 120V/60Hz/15A (standard North American mains) or 230V/50Hz/15A (international mains). The system requires no external compressed air, water, or additional utilities — a grounded mains outlet at the appropriate voltage is the only external service connection needed. The entire system must be properly grounded before operation; correct earthing is a mandatory safety requirement. When running on a 50 Hz supply, nominal flow rate decreases from 26 GPM / 1,560 GPH to 20.8 GPM / 1,248 GPH.
The pressure gauge on the MTC-3000 is mounted between the pump outlet and the spin-on fine filter housing. As the filter element accumulates contamination and begins to restrict flow, the gauge reading rises progressively during operation. When the needle reaches 20 to 25 PSI — or enters the red zone on the gauge dial — the fine filter element has reached its capacity and should be replaced before continuing the polishing session. If a freshly installed filter immediately generates a high pressure reading at start-up, this indicates a discharge-side restriction such as a closed outlet ball valve or blocked discharge line rather than a filter condition issue, and should be investigated separately before running the pump.
