Lubrication is a prime requirement for all machines, equipments or plants as it adds to the life and efficiency of the the machine by reducing wear and tear of its parts. The lubricating oil forms a film between the moving parts which results in lesser friction and correspondingly less heat generation in the machine, thereby keeping the working temperature of machine parts within safe operating limits. Wear and tear of parts is thus greatly reduced resulting in fewer breakdowns, greater machine utility, lower maintenance cost and longer machine life.
