Skey Products offers a Motorised Lubrication Unit, Model LMU-2.7/PS/FS. This is a centralised lubrication system, which delivers predetermined quantity of oil to various lubrication points of a machine at preset time intervals. It consists of highly efficient positive displacement pump driven by FHP motor, relief valve, pressure switch, pressure gauge, float switch and level gauge. The relief valve safeguards the system from overloading, and the gauges provide the reading. The unit is designed for intermittent operations, the frequency of operation of the pump controlled through an electronic controller. If case there is any fault in the system, the system will not work and the pressure switch activated by oil pressure provides the indication of such a situation on the panel of electronic controller. The float switch senses the oil level, and gives an indication when oil in the tank drops below the safe level. Each time when the unit is switched on the metering cartridge discharges a predetermined quantity of oil at the lubricating point. The unit with its high performance controller automatically controls and monitors the working of the lubricating pump.
