Manzel Model 25 Force Feed Lubricators are economical, general purpose units of double plunger design for precise metering of lubricants (either mineral oil base or synthetics). All working parts are totally enclosed—away from dust, water and impurities—and self-lubricated at all times by the lubricant in the reservoir.
They provide lubrication to cylinder walls, bearings and other moving parts of equipment such as sugar mills, steam engines, presses and general machinery.
