Submerged agitators

Advantages of using PILVAD side entry agitators on drilling-mud vessels.

 

Submerged agitators

are smaller than the side entry agitators, with shorter shafts and off
course must be completely “sealed off” towards the drilling mud. They should be fixed to
the wall of the inside of the tank, to provide good performance. The required filing level is
low for the submerged agitators. It is very important is that the tank is equipped with
guider rails for pulling the whole agitator up from the tank, in case of a leak. The
repositioning of the submerged agitators is also required to ensure sufficient agitation of
the mud in all corners of the tank. Submerged agitators are in greater risk of leaking as
the complete machine is encapsulated in drilling mud. If a leak should appear, it is
possible that the whole agitator is damaged. Maintenance and replacement is lengthy and
costly and is likely to delay the delivery of mud to the platform.
