ABSTRACT:
A lubricating recirculation system for use with highly viscous lubricants and semi-fluid lubricants such as high viscosity base oil gels and greases. The system includes a bulk lubricant container for storing fresh lubricant that is applied to the use points of the mechanisms as controlled by a controller such as programmable logic controller. After application to the mechanism components, the lubricant falls therefrom and accumulates on guards or channels which help to funnel the lubricant into a spent lubricant holding tank. Sensors in both the bulk lubricant container and the spent lubricant holding tank, in connection with the controller, monitor the level of lubricant in both tanks and activate a transfer pump when the level of lubricant in either tank reaches a certain level. Upon activation of the transfer pump, the spent lubricant is drawn from the spent lubricant holding tank and forced through a filtering device to remove impurities and is then conveyed back to the bulk lubricant container for reapplication to the use points.
