Filtering Bulk Fluids

Largo are proud to Introduce Bulk hP, a line of filters from Donaldson Clean Fuel & Lubricant Solutions. These are perfectly designed to filter fluids being delivered up to 1000 PSI (69 BAR).

High pressure delivery is the process by which piston or diaphragm pumps are used to transport hydraulic fluids, oil and lube from remote storage tank locations into equipment. The 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 today’s equipment OEMs. End-users need a filter with high dirt holding capacity and efficiency that’s easy to change and dispose of in an environmentally friendly way.

Largo recommends the following ISO cleanliness levels: 

  • Hydraulic/transmission ISO 16/14/11.
  • Lubes/gear oil ISO 18/16/13.

The Bulk hP filters supplied by us remove any contaminants that may have been picked up in storage or delivery lines during final transfer. This ensures that the required ISO cleanliness levels are met every time.
