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
