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.

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.
