FUEL WATER SEPARATORS FOR
Mining Filtration Systems
DAVCO mining filtration equipment is built for the most punishing off-highway conditions. Across haul trucks, shovels, support fleets, and site gensets, our units protect diesel engines against the water, dirt, and debris that drive up the cost of ownership in mining. Reliable diesel fuel filtration for mining has to hold up in the open, where the equipment actually runs.

Mining Equipment Filtration Systems Built for the Harshest Duty Cycle
One of the most demanding applications DAVCO products are engineered for is mining filtration, and it shaped the product line itself. The Industrial Proยฎ series was designed with input from leading engine manufacturers to match essential mining filtration system requirements.
Between severe vibration, constant exposure to mud and rock, and around-the-clock runtime, mining equipment filtration systems face stresses that on-highway units do not typically see.
| On-Highway Units | Haul Truck Units | |
|---|---|---|
| Where the unit sits | Tucked under the hood | Out behind the wheel well |
| Environmental exposure | Sheltered under the hood | Takes on everything the environment throws at it |
| Duty-cycle stresses | Does not typically see the stresses mining units face | Severe vibration, mud and rock, around-the-clock runtime |
The Fuel Contamination Challenge in Mining
The single biggest threat to diesel fuel at a mine site is water intrusion, and it starts long before the fuel reaches the machine. Before it reaches a haul truck, fuel can travel from:
- Rail cars
- Storage tanks
- Fuel trucks
Every container change adds another point of contamination. Tanks sitting in open yards take on condensation as they heat and cool, drawing emulsified water into the fuel.ย That emulsified water is exactly what mining diesel fuel filtration systems are built to pull out before it reaches the injectors and pumps.

DAVCO Protection for Mining Fleets
DAVCO matches the right mining filtration products to each machine and its fuel-flow requirements:
- Haul trucks and large shovels โ Industrial Proยฎ Tall Dual units, sized for the high fuel flow of 60-liter-and-up engines
- The largest haul trucks โ Industrial Proยฎ Tall Triple units for 70-liter-plus Cummins, MTU, and 95-liter-class engines
- Support and construction equipment โ Graders, excavators, front-end loaders, and drills run on Industrial Proยฎ single units or Fuel Proยฎ 300/400 series, depending on engine size
- Gensets โ Sized to the generatorโs fuel flow, spanning Fuel Proยฎ and Industrial Proยฎ units
- Underground mining โ All-steel Sea Proยฎ units, chosen for robustness and to meet the stricter flammability codes underground operations require
Cutting Downtime in Remote Operations
When every second counts, mining diesel fuel filtration systems have to operate at peak efficiency. In mining, downtime is measured in thousands of dollars per hour.
A single shovel down for injector repair can idle every haul truck feeding it.
The bottom line: Unplanned fuel-related failures are among the most expensive events on a mining site.
DAVCOโs Seeing Is Believingยฎ clear-cover technology turns a mid-shift breakdown into a check the operator makes without breaking the seal.
Selecting the Right Mining Filtration Products
Mining fuel filtration systems from DAVCO offer:
Because DAVCO provides a range of products from 60GPH to 1,800GPH, a mine can standardize DAVCO across a mixed fleet; it may simply be a different unit for each machine but the same great engine protection. The best starting point is to work with a member of DAVCOโs off-highway technical sales team, with these on hand:
- Your engine make and model
- Maximum fuel-flow rate
- Current filter setup
