3  Separator Basics

3.2  Design and function

Water seal in purification

To prevent the oil from passing the outer edge of 
the top disc (I) and escaping through the water 
outlet (221), a water seal must be provided in the 
bowl. This is done by filling the bowl with water 
through the water inlet (206), before unseparated 
oil is supplied. When oil feed is turned on the oil 
will force the water towards the bowl periphery 
and an interface (X) is formed between the water 
and the oil. The position of the interface is 
determined by the inner diameter of gravity disc 
(K).

Displacement of oil

To avoid oil losses at sludge discharge, 
displacement water is fed to the bowl.

Prior to a discharge the oil feed is stopped and 
displacement water added through the water inlet 
(206). This water changes the balance in the bowl 
and the interface (X) moves inwards to a new 
position (Y), increasing the water volume in the 
sludge space. When the sludge discharge takes 
place sludge and water alone are discharged.

Sludge discharge occurs while the displacement 
water is still flowing. A new water seal will 
therefore establish immediately afterwards. The 
oil feed is then turned on again.

Gravity disc

In the purification mode, the position of the 
interface (X) can be adjusted by replacing the 
gravity disc (K) for one with larger or smaller 
diameter.

A gravity disc with a larger hole will move the 
interface towards the bowl periphery, whereas a 
disc with a smaller hole will place it closer to the 
bowl centre.

The correct gravity disc is selected from a 
nomogram, see ‘‘8.6.6 Gravity disc nomogram” 
on page 166.
