Lubricating Type |
| Similar to standard stuffing box but an addition of a wiper ring of packing before the inboard bushing to prevent contaminates from galling up surfaces between the bushing and the shaft. |
When service requires additional lubricant, a lantern gland and a pipe connection can be furnished. Additional packing rings below gland prevent lubricant from entering the stream. |
