AMETEK Spectro Scientific
Compressor oil analysis Pumps are used in industrial and fleet applications to move liquids and gases. Most pumps used in industrial applications are either positive displacement or centrifugal. In both cases bearings are the component that must be lubricated and monitored. Rotary positive displacement pumps have gears, screws, lobes or vanes which are also lubricated, usually by the fluid they are pumping, whether it is a lubricant or an oil /air mix. Bearing failures are the second leading cause of pump repairs... (read more)Browse Oil Sensors and Analyzers Datasheets for AMETEK Spectro Scientific
