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.

Glycol (Ethylene Glycol, Ethylene Alcohol)
A clear, colorless, syrupy liquid used in a variety of applications involving lacquers, resins, printing inks, adhesives, waxes, and pharmaceuticals. It is often blended with water and used as a coolant and anti-freezing agent.
