Centralized grease lubrication systems are widely used in industrial and heavy-duty mobile equipment applications to lubricate multiple points on a machine. These systems range from a simple single-port lubricator to complex dual-line, reversing units employing timers and alarms to deliver grease reliably to hundreds of grease points. The design parameters of centralized grease systems include the volume and frequency of grease required at each point, the number of points requiring grease, operating conditions, pump pressure, line diameter, and distance to the grease points.
