The KFG, KFGS and KFGC series pump assembly (CAN control unit) is an integral component of centralized lubrication systems used in devices and systems. They supply NLGI Grade 2 lubricants. Pump assemblies vary in grease reservoir capacity, filling, control and function monitoring. Installing pump components with a specific volume allows a single KFG or KFGS series unit to service three independent zones. The KFGC series is capable of supporting up to four independent zones, depending on the task. The system may or may not be equipped with functionality to monitor pressure increases or decreases.
