The filters from Donaldson Clean Fuel & Lubricant Solutions filter fluids and are being delivered up to 1000 psi (69 bar) and are widely employed in the mining industry. High pressure delivery is the process by which piston or diaphragm pumps are used to transport oil, lube, and hydraulic fluids from remote storage tank locations into equipment. These pumps operate on compressed air to force fluids through long lengths of piping and hose reels at delivery pressures significantly greater than the original air pressure. These high pressures force fluids through piping and deliver product out of hose reels and into equipment. Filtering fluids stored in bulk tanks prior to being delivered into equipment is critical to meet the ISO cleanliness specifications demanded by Original Equipment Manufacturers (OEMs). End-users need a filter with high dirt holding capacity and efficiency, which is also easy to change and dispose of in an environmentally friendly way. Donaldson adds that the Bulk hP filters offer extended life - DX-2 media has 50% more dirt holding capacity than a filter the same size. They are also easy to dispose of. The filter element easily separates from the housing; all-metal cans are 100% recyclable and non-metal elements are 100% incinerable. The filters are constructed for heavy duty use – the 300 psi/20 bar collapse pressure prevents dirt from passing even under extreme pressure drop conditions. The filters are claimed to provide protection for all applications. Three different micron media options are available to fit all fluid types and viscosities.
