How does central lubrication work?

Central lubrication systems supply several lubrication points on a machine in an automated, reproducible and needs-based manner. This reduces manual maintenance costs, the lubrication quality remains constant and downtimes are reduced.

Why central lubrication?

• Less wear and longer service life of components
• Plannable maintenance instead of ad-hoc deployments
• Reduced lubricant consumption through defined quantities

System types at a glance

• Introduction – compact, for short lines and moderate scores
• Dual line – robust for long cable routes and many points, especially a. Fat
• Progressive – fixed distribution logic, good monitoring of individual circuits
• circulation (oil circuit) – continuous oil supply including cooling effect
• Minimum quantities (MMS/oil-air) – very precise dosage, clean applications

Core components

• Pump/unit: Performance & pressure suitable for the pipe network and medium (oil/grease)
• Doser/distributor: Single/dual line, progressive or oil circuit
• Lines & Fittings: dimensioned according to distance, temperature and viscosity
• Sensor technology: Pressure, flow and stroke sensors for messages/alarms
• Steering: Interval, quantities, faults – connection to HMI/PLC

Selection criteria

• Number of lubrication points & line lengths
• Medium: Oil (viscosity) or grease (NLGI 00-2)
• Temperature window, environment, hygiene requirements (H1 optional)
