Motorised Lubrication Unit

Automat has designed and manufactured motorized lubrication units for centralized automatic lubrication. These are electrically driven motor pumps containing reservoir, oil filler, suction strainer, bleed valve, pressure gauge, pressure relief valve etc. They are available both in MS and imported acrylic body.

Operational Theory
During On time of the motor, which is normally 5 seconds, metered amount of oil is ejected from all the metering cartridges to lubricate the lubrication points. These metering cartridges are again recharged during OFF time of the motor. The outlet port of the pump is normally M10 X 1. Additionally pressure switch and float switch is applied to control over the oil presence and pressure. A lubrication timer / controller is also used to get the oil on required intermittent basis. An oil indicator is used to visualize the minimum oil level. Automat has added the provision of return line filtration with some models to re-consume access oil after it get filtered.

Distribution of Oil

Normally a main 6 mm line from pump to manifolds is send on which required metering cartridges are fixed. Additionally a secondary line is arranged with 4 mm tube is applied to connect all the lubrication points.

We must always use oil with proper viscosity range which is 50- 150 cSt for transparent acrylic units and 50- 1000 cSt for MS body. We should be regularly careful with the power connection to avoid motor burnt. Additionally we should fill oil before going its level below the 'Minimum Oil Level' position to avoid entering of air in the unit.
