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.

Biofuels
Biofuels include Biodiesel and Ethanol. These are fuels made from renewable resources and typically blended with refined fuels as additives.

Refined Fuels
Refined fuels would include petroleum based fuel oils and some Jet Fuels. Their viscosity and temperature handled can vary greatly. Normally these are handled in bulk transfer operations.

Lube Oil (Machinery Lubrication)
Machinery lubrication pumps are used in everything from small backup generators to naval ships. Lube oils, as the name implies, are the liquids used to lubricate rotating and reciprocating machinery. Lube oils may be handled at higher pressures to ensure their penetration of the equipment.

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.
