Constant Level Oilers

Constant-level oilers are used to check the lubricant quantity (e. g. in rolling element bearings). They are designed to maintain a predetermined oil level in a sump, which is necessary for proper lubrication. If the oil level drops below a certain point, the depleted oil automatically self levels based on the lubricators volume.

As long as the reservoir of the lubricator contains oil, the oil level in the bearing housing is sufficient to ensure reliable lubrication.

Widely used in the chemical and process industries, constant level oilers maintain a constant fluid level at all times. Available with BSP or NPT thread. Plastic or glass reservoirs with capacities of 85 cc to 500 cc.
