About the Graco automatic lubrication equipment

Single-line parallel: a pump sends lubricant down one line to injectors, each injector meters a set amount per cycle and shows it cycled with a pin; line pressure is vented between cycles. Series progressive: a pump feeds a divider valve whose pistons move in sequence, so each outlet gets a measured amount; if flow stops the pistons stop and resume from the same point. Graco lists uses such as: in-plant machinery lubrication (LubePro, Lube Master, Manzel). Graco GL-series injectors are metering devices for single-line parallel automatic lubrication systems. In a series progressive system a divider valve passes lubricant to each outlet in sequence; if flow stops, the pistons stop and resume from the same point.

• Injector: Metering device delivering a set grease amount to one point.
