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.

Remote-Mount Springs—Remote-mount springs (sold separately) provide extra pressure when using thick grease at a distance.

Powered by your air system, these dispensers release a precise amount of grease in timed intervals, so your machine will never have too much or too little. They’ll dispense the right amount even if changing temperatures affect the grease consistency. Back pressure doesn’t impact these dispensers either. But compared to motor-driven dispensers, they’re more complicated to set up. Besides your air system, you’ll need to attach a three-port solenoid valve and either a timer or programmable logic controller (PLC) to control the valve (all not included). If you use a PLC, they’ll prevent over-lubrication when your machine is down by only greasing when it’s running. This is useful for machines with intermittent downtime. Even without a PLC, you can manually cut off the flow without uninstalling the dispenser.

They’re modular, so install or remove pumps as your lubrication needs change. Each pump has mounting holes drilled through their body. Use a screwdriver to turn each pump’s flow-adjustment screw.

These dispensers don’t come with grease, so use the grease that’s best for your machine.

For use in clean environments, these oil reservoirs have multiple air vents that keep pressure balanced. They 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 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).
