This Series electric lubricator includes a motor-driven gear pump of superior structure.can use lubricating oil with viscositybetween 30cst-00#. Its oil tank volume has three specifications of 2 liters, 4 liters and 8 liters.This kind of pump is equippedwith a level switch, while a pressure switch can be provided according to diferent applications. These are connect-ed withproqrammed controllers on the pump, or programmed control system on main user eguipment to control and monitor oilevel in reservoir, supply system pressure and setting of lubrication cycle. lt is widely used in centralized lubrication systemsfor machine tools, plastics, textiles, ight industry, printing, auto escalators and conveyers, among other mechanica equipment.
