Grease feeders and precision metering pumps automatically dispense lubricant to moving machine components to keep them greased to proper levels without requiring manual checks. This helps save maintenance time and avoids having employees go near dangerous moving parts to grease equipment. Grease feeders and pumps maintain a consistent level of lubrication to critical components such as bearings, slides, gears, and chains to avoid equipment breakdown or malfunction. They are less messy than manual grease guns and can reduce the chance of damage caused by spilled grease. Grease feeders, also known as single-point lubricators, can supply lubrication to a single point. Precision metering pumps can supply lubrication to multiple points.
