NETZSCH permanent lubricator

The Permanent Lubricator is used to support the sealing function of the shaft seal. It can be used for packed glands as well as mechanical seals fitted with an additional quench ring. The function of the Permanent Lubricator is to continually keep grease in the grease chamber ring or quench pot under pressure by means of a pre-stressed spring. A shut-off device on the lubricator can be activated to accommodate periods when the pump is idle.
