Abstract
A lubrication system for supplying viscous, solvent-based, lubricants to heavy industrial plant, such as a driving gear of a sugar mill comprises a reciprocating lubricant pump which is periodically actuated to deliver lubricant to a spray head. Air is supplied under pressure to the spray head to effect discharge of the viscous lubricant in spray form. The air supply continues for a pre-determined time after discharge of the lubricant to evaporate solvent in the lubricant and also to clean the spray device. The pump effects a single stroke for each cyclic discharge of lubricant.
