Gear Pumps belonging to PEX Series are used for transferring that category of Viscous and Semi-Viscous liquids, which because of their offending nature could not be entertained by pumps of PSG Series. Here this snag is removed by locating the bearings outside the pumping chamber where they remain out of the reach of the inner criminal atmosphere and are lubricated independently.

Recommended for liquids like crude oil cotton seed oil, dirty lube oil, High Speed Diesel, Light Diesel, Resin, Varnish, Transformer oil, Molasses, Glue, Glycol, Cream, Sugar Solution, Starch and so on. Jacketed Version of these pumps are also available to handle Silicate, Soap Solution, Wax, Petroleum Stock, Viscouse, Neptha and cellulose.
