The right choice

PILVAD supplies side entry agitators – the right choice.

 

The right size


PILVAD produces side entry agitators in various sizes. They all have short and strong
shafts, a powerful motor and are mounted close to the bottom of the tank.


The right place


This fixed position is an advantage as it gives the possibility to address the mixing power
exactly at the preferred place: the center of the bottom of the tank, where the sediments
occur.
 

The right performance


PILVAD side entry agitators give a good mixing performance, with a well known flow
pattern and ensure that all sediments are suspended to provide as efficient use of the
drilling mud as possible

The right system


PILVAD agitators are equipped with a standard mechanical seal towards internal side of
the mud tank to prevent leaks. We also provide a special system for replacement of the
seal, called a “shut off device”.
This device is a well integrated part of PILVAD side entry agitators and secures easy repair
of the sealing system.
 

The right approach


With the “shut off device” You do not need to remove the agitator nor have to empty the
tank. To prepare the seal change the PILVAD agitator is stopped, and the shaft is pulled a
short way towards the tank wall whereby a built-in o-ring seals the tank. Thereupon
follows the disassembly of motor and gear and finally the change of the seal.
 

The right know-how


Given the needed spare parts, equipment and tools a skilled and trained operator is able
to completely change the seal in 2 hours, in the odd case that a leak is spotted.
All of this is described in the attached folder: Replacement of mechanical seal.
