The innovative Pulsarlube S has a very unique and scientific design. Conventional spring type lubricators contain a ball valve to be able to control the flow rate of the lubricant. Such mechanism makes it very difficult to control the dispensing rate on this type of lubricator. Another fact that applies to spring type lubricators is that the spring constantly pushes down on the lubricant, thereby causing oil separation. When oil separation occurs, gravity allows the oil to drip out from the bottom, leaving only the thickener behind in the lubricator's chamber.
The Pulsarlube S is an advanced spring type lubricator which operates with the spring at the bottom and an upward piston movement which dramatically reduces the effects of oil seperation that have long plagued traditional spring type lubricators.
