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.
