Lincoln Offers High-Volume Grease Pumps
Lincoln has introduced its new High Volume PowerMaster Grease Pumps.

Designed for the quick transfer of grease from drums and bulk containers, the 12:1 and 24:1 pumps are ideal for filling automatic lubrication system reservoirs, transferring grease to smaller containers and feeding measuring ejectors with restricted priming pressure.

The pumps offer positive priming with a shovel-type foot valve and provide 60 percent more output/stroke than Lincoln’s previous highest volume PowerMaster.
