Skf 84804 Lincoln Powermaster 3 Air Motor, 4 1/4"

Designed to fit large drums or containers, PowerMaster III pump units are ideal for lubrication systems using substantial quantities of lubricant. The modular combination of various air motors with pump tubes enables optimum adaptation to lubrication system requirements. The PowerMaster III is available in carbon steel to fit any drum size. A complete line of priming equipment and mounting devices are offered.

PowerMaster III pumps are compact powerful, pneumatically-driven pumps to supply lubrication greases and oils as specified in chapter ’Technical data’. To supply lubricant the supply piston inside the pump tube carries out up-and downward movements. In combination with the Lincoln pump hoist (5) and a follower plate (6) the PowerMaster III pump can be driven also as a barrel pump. In this case, the follower plate is seated on the surface of the material to be supplied and lowers down into the round or rectangular container while being emptied. When reaching the adjusted minimum filling height (low-level indication) the PowerMaster III pump is switched off.

Designed for heavy-duty applications such as mining, construction and printing ink Rugged design with minimum moving parts provides maximum reliability and durability in heavy-duty applications.
