What is GREASOMATIC?
It is a self-ejecting canister of lubricant designed to screw into a grease nipple socket or other lubrication point, and discharge its content of 120ml of lubricant in a controlled continuous flow, for a preselected period of between one month and twelve months. It is completely self-contained and needs no pumps, motors, electricity or compressed air. Once fitted and activated it will work without attention until its allotted lifespan is over.
How does it work?
Each GREASOMATIC contains its own unique chemical expulsion unit. This has no springs or mechanisms but relies on an unvarying law of nature. Built into the top of each GREASOMATIC is a flexible rubber expansion chamber containing a liquid electrolyte and a galvanic element. The unit is activated by injecting the galvanic element into the electrolyte.
The resultant electro-chemical reaction generates a steadily increasing amount of gas, which gradually expands against a piston, to extrude the lubricant slowly but surely into the bearing to which the GREASOMATIC is fitted. The chemicals and gas remain hermetically sealed within the expansion chamber so that no contamination of the lubricant can occur, even after the unit itself is spent. During the working life of the GREASOMATIC, an indicating ring on the ejection piston shows through translucent windows in the body to enable the discharge state to be monitored.
The Pressure Relief Valve
This is provided to guard against the possibility of the GREASOMATIC being fitted unwittingly to a bearing with blocked greaseways. Should the pressure built up by the GREASOMATIC prove insufficient to clear the blockage, the valve will open to allow the lubricant to escape and prevent excessive pressurisation of the GREASOMATIC. The exudation of lubricant around the GREASOMATIC will serve as a warning that the greaseways are blocked and that no lubrication is taking place.
