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.
