Lubrication Systems

Automatic lubrication systems deliver a precise amount of lubricant to multiple points on equipment while it is operating. Instead of manual greasing, these systems use pumps, metering devices, and distribution networks to ensure every critical component receives consistent lubrication. This reduces friction and wear, improves reliability, and lowers maintenance costs.

There are many types of lubrication systems, such as single-line, dual-line, volumetric, air-oil, and minimum quantity lubrication setups. Each is suited to specific equipment and operating conditions.

The example shown here illustrates a Series Progressive System. In this design, an electric pump delivers lubricant to a primary divider valve, which then meters the lubricant in sequence. The flow is distributed through feed lines to secondary dividers or directly to lubrication points, ensuring each point receives the correct amount at the right time.

1. Electric grease pump supplies lubricant from the reservoir.
2. Transparent reservoir makes it easy to monitor lubricant level.
3. Nipple (zerk fitting) for filling allows convenient refilling of the reservoir.
4. Pump element pushes lubricant into the system under pressure.
5. Pressure gauge shows system operating pressure.
6. Overflow valve protects against over-pressurization.
7. Integrated timer controls system cycles and intervals.
8. Progressive primary divider receives lubricant from the pump and begins distribution.
9. Progressive secondary dividers split and meter lubricant to additional lines.
10. Primary feed line connects the pump to the primary divider.
11. Secondary feed lines carry lubricant from the primary divider to the secondary dividers.
12. Tail lines deliver lubricant directly to critical lubrication points.
13. Discharge ports ensure each point receives the precise amount of lubricant.
