General

The machine described in this manual is a high-speed centrifugal separator with
self-cleaning bowl.
"Separation" means the separation of liquid mixtures which consist of two liq-
uids, with simultaneous removal of the solids contained in the liquids.
"Clarification" is the removal of solids from a liquid.
Prerequisite for treatment technology (separation) is that the components of the
product
– can be separated mechanically,
– have different densities and
– do not emulsify.

OSD ...-91-...

The separator OSD ...-91-...
• is equipped with a self-cleaning disk bowl,
• is used for clarification and separation in fuel and lube oil treatment plants
(fuel oils up to a density of 0.991 g/ml),
• operates with regulating rings (see section 2.6).
The most important part of the separator is the bowl. The bowl
• is configured as a purifier bowl at the factory,
• can – depending on the application – be converted to operate as a purifier
bowl or clarifier bowl.
Converting the purifier bowl to a clarifier bowl and vice versa is possible in just a
few easy steps (see diagrams).
