Fill the reservoir, attach the propellant cartridge, and spray.

A sealed design prevents contamination in dirty and dusty environments. Install a line between the reservoir's pressure port and the lubricated equipment to balance pressure. Designed to maintain a constant level of oil in bearing housings, gear boxes, and similar closed machinery, when oil falls below the set level, these reservoirs automatically replenish the supply. They have oil outlets on the side and bottom for flexibility in installation. For applications that require adjustable flow control, pair with a flow-adjustment valve (sold separately).

A spring delivers a constant, low-pressure flow of grease to your lubrication point, so it never runs dry. They’re best for applications with consistent temperatures, so the viscosity of the grease won’t change how quickly it flows. However, they shouldn’t be used in precision applications because the tension of the spring may change, causing the dispensing rate to change. Mount them close to the lubrication point. They have a standard grease fitting, so you can choose what grease to use, unlike prefilled dispensers. The grease fitting helps close the system to keep out dust and contaminants in dirty environments such as mills. Use grease fitting adapters to match your lubrication point.
