Diesel (#2 Fuel Oil)
Diesel is distilled from petroleum and is typically used in heavy equipment as fuel. While it is thin diesel is somewhat lubricating. It is typically handled in a bulk transfer application or on back-up generator skids.

Crude Oils
This is a very generic term for unrefined oils typically being recovered from the ground. Some crude oil may contain particulates from the oil well or recovery method. They are considered to be flammable liquids. Crude oils are later refined and used for everything from making plastics to gasoline.

Asphalt Cement
Clean asphalt contains no fillers and is an oil based liquid. It is primarily used in paving roads, waterproofing liquids, and paints. Typically they are handled at elevated temperatures to reduce the viscosity of the asphalt. The pump needs a source of heat like jacketing or electric heat to prevent the product from solidifying in the pump.

Asphalt Emulsions
Emulsions are asphalt suspended in a mixture with water or other liquids. This is done to ease the application of the asphalt. Uses would be crack filling, coating roadways, or waterproofing. These emulsions are shear sensitive and must be handled with care.

Filled Asphalt
Filled asphalts contain particulate used in the liquids’ end applications. Examples of this would be roofing materials and hot mix plants. Typically they are handled at elevated temperatures to reduce the viscosity of the asphalt mixture. The pump needs a source of heat like jacketing or electric heat to prevent the product from solidifying in the pump.
