Agitator Seal

Agitator seal, agitators and vessels vary according to their position on the vessel, that is, whether the rotating shaft is top, side or bottom entry. Also, the material of the vessel, whether it is steel or glass lined, has a significant influence on the seal design. Seals for top entry vessels are expected to retain the gas or vapour above the fluid in the vessel. To do this, double seals are normally recommended, although for very light duties a single seal can be used. Unlubricated or dry running seals are being increasingly applied because they avoid the need for a seal lubricating system.
