These are offered in various different models. To safeguard the system from overloading a relief valve is provided in the line. By adjusting the relief valve the line pressure can be set to the required value. The line pressure can be read on the pressure gauge provided on the unit. The lubrication unit is designed for intermittent operations. The frequency of operation of the pump is controlled through the electronic controller. If there is any fault in the system like choking of filter, low oil level, leakage and motor or pump failure the lubricating point won’t be lubricated. A pressure switch is provided to indicate such a situation. The switch is operated by oil pressure.
In case due to some fault the pressure doesn’t exceed the preset pressure the switch will not be operated and there will be an indication on the panel of electronic controller. To sense the oil level condition in the tank a float switch is provided. It gives an indication when the level of oil in the tank drops below the safe level. Each time when the unit is switched on the metering cartridge discharge the predetermined quantity of lubricating oil at the lubricating point. The Motorised Unit with high performance controller. Which automatically controls and monitors the working of the lubricating pump. The unit facilitates precise control over the frequency of the oil dosages and also monitors the oil level. In case of low oil level in the reservoir , unit stops automatically with an indication on the panel.
