After suffering operational snags relating to substandard fuel qualities reducing a Zambian copper mine’ s haul-truck fleet’ s runtime capacity to 65 %, the fleet attained utilisation rates of between 85 % and 90 %. The targeted 350-hours service intervals on the fleet’ s fuel filters were not being achieved owing to sporadic blockages. Fitted with Cummins QSK50 MCRS engines, onboard filter, injector, and injectorpump failures were occurring.
A Fleetguard service team found that the bulk fuel was cloudy and muddy, and had not been delivered according to specifications, containing water and fungi. Fungus only occurs in fuel in the presence of free water, increasing the probability of injector failures.
Cummins Filtration inspected the mine’ s on-engine filtration system, specifically at the fuelsupplier’ s maintenance, the results achieved, and the quality of the tests undertaken. The engines were also

inspected, including the onboard filtration systems. Part of Cummins’ recommendations was to fix the water contamination situation in the fuel. They contracted clean-fuel solutions provider SupaFuel as an independent party to verify that in fact, water was present in the fuel, to put the correct maintenance practices in place and to manage the mine’ s bulk fuel system. It also implemented the recommendation from Fleetguard in terms of the mine’ s onboard filtration systems.
SupaFuel owner Chris Chow adds that it produced a report on the mine’ s bulk fuel situation, citing that the water had to be removed to maintain the purity standard of the bulk fuel. Cummins Filtration upgraded the mine’ s first-stage bulk fuel filtration system to a FH239 Series Industrial Pro ® in the first stage of the upgrade, providing contaminant removal at 99.9 % efficiency, or ß1000 at seven microns.

During the second stage, a FF5782 fuel filter was installed with an allin-one fuel / water separator with NanoNet ® media. NanoNet ® provides a final-stage filtration solution using the same nanofibre media technology as in the Fleetguard NanoForce ® air filters, improving performance by up to 13 times of standard filters.
The advantage of the FH239 Series Industrial Pro ® is that it meets and exceeds OEM efficiency requirements, while the 67 % increased media area ensures greater engine protection, providing the highest level of fuel / water separation and reduced flow restriction by up to 9 %.
Since the solution was implemented in June 2017, the mine’ s downtime has reduced significantly, resulting in longer service intervals on the haul trucks, increased oil lifespan, and improved equipment availability. This equates to significant improvement in
