851E-3 Fuel/Water Separator

The Model 851E Series are diesel fuel/water separation and filtration filter vessels that employ Kaydon Filtration coalescing technology to separate water from diesel fuel.  In addition to water removal, the coalescer provides a particulate filtration layer to remove harmful particulates along with providing protection for the coalescing stage.  The 851E vessels are designed from rugged, heavy-duty, carbon steel and built per ASME Code.  The Model 851E Series are designed to provide filtration and water removal for Diesel # 1 and # 2.   

The Model 851E Series can be used as an in-line fuel purifier in fuel transfer applications in the following areas:

Marine – Filtration during fuel transfer from storage tanks to day tanks

Bus and Truck Terminals – Final fuel conditioning before fuel enters vehicle

Agriculture, Construction, and Mining – Filtration during fuel transfer from delivery truck to storage tank or from storage to tank to equipment

Airport Operations – Provides clean fuel as the fuel is transferred into airport ground support equipment.

Railroad - Filtration during fuel transfer locomotive fuel storage tank

All other types of off-road machinery fuel transfer operations  

BENEFITS 

  • ASME Code Construction: Using the ASME Code design criteria, the Model 851E Series are built for reliable and long term use in any industrial fueling environment. 
  • Engine Protection:  Protects today’s highly sophisticated fuel injection systems, thereby keeping diesel powered equipment in service.
  • Clean Fuel Delivery:  Prevents premature replacement of expensive components and revenue loss from equipment downtime resulting from contaminated fuel.
