Patent ID: 8714309

Claim:
An improved pump-to-point, closed loop lubricating system for high pressure machinery comprising a pressurized feed pump for supplying food grade oil to the high pressure machinery wherein the pressurized feed pump comprises a cam, a lever and a bushing, a first reservoir containing lubricating oil for lubricating the cam, the lever and the bushing of the pressurized feed pump, a second reservoir containing the food grade oil for use in the high pressure machinery, and a differential pressure flow meter wherein an amount of food grade oil is supplied to the high pressure machinery from the second reservoir via the flow meter by the pressurized feed pump at one or more machine injection points, the food grade oil is not in contact with the cam, the lever and the hushing of the pressurized feed pump and is monitored by said flow meter connected to a computer, the computer being capable of producing an audible and/or visual warning, shutting down the system or adjusting the flow of lubricant to the pressurized feed pump or machine injection point.
