Lubricator Drip Rate

Question

How do I properly set the drip rate for my lubricator?

Environment

To assist customers with the proper setting of Lubricator drip rate.

Answer

Note: Lubricator adjustments need to be made with a constant rate of flow through the lubricator in operating mode.

Depending on your model, you may need a small screwdriver to adjust the drip rate. The adjustment screw (or knob on some models) is located in the sight feed cap on the top of the lubricator. Observe the markings (-,+) on the lubricator body which show direction. Turn the adjustment screw counterclockwise to increase and clockwise to decrease.

Determine the average rate of flow (SCFM) through the lubricator, then turn the adjustment screw to obtain one to two drops per minute for each 10-20 SCFM. Example: If the average flow is 30 SCFM, set the drip rate at 2-3 drops per minutes to start.  Monitor equipment condition and increase or decrease drip rate as necessary to keep the equipment sufficiently lubricated.
