Abstract
A system generally including a delivery module and metering modules adapted to deliver grease to process valves. The metering modules each include a grease metering device including either: a grease cylinder, a piston extending within the grease cylinder, and a first actuator; or a casing, a rotor extending within the casing, and a second actuator. The delivery module includes a grease container and a fluid transport device adapted to deliver grease from the grease container to the grease metering modules. A control unit is adapted to control: the first actuator(s) to stroke the piston(s) within the grease cylinder(s) so that respective amounts of the delivered grease are metered to the process valves; and/or the second actuator(s) to rotate the rotor(s) within the casing(s) so that the respective amounts of the delivered grease are metered to the process valves.
