A LEADER IN CENTRIFUGATION

PRINCIPLES OF THE SEPARATIONSYSTEM

The decanter is used for the

separation of two or more

phases of different specific

gravity, in particular for the

clarifying of liquids in which

suspended solids are

present. The separation of

solids and liquids takes place

within a cylindrical/conical

rotating bowl, upon the

periphery of which the

heavier solid phase collects

and is continually removed by

the internal conveyor.

A polyelectrolyte, suitably

chosen for its type and

specific characteristics, may

be added to the product

being fed to the machine in

order to improve the solid-

liquid separation.

The polyelectrolyte favours

the aggregation and thus the

easier capture of the solid

particles. A polyelectrolyte is

not always compatible with

products being processed.

It is generally used in

purification processes for the

drying of sludge, but not in

intermediate product

conversion processes, and

even less in the processing

of foodstuffs.

SolutionsSeparation

Division

The Pieralisi Group provides

solutions to all technological

problems of solid-liquid and

solid-liquid-liquid separation,

thanks to the great

experience and know-how

developed over time in the

most important industrial

centrifuge markets. Over

40,000 Pieralisi machines

and plants are today installed

worldwide, being used in a

wide variety of centrifugal

technology applications, as

evidence of the undisputed

market leadership of the

Pieralisi Group.

� Two- three-phase design

� Conveyor and bowl in

various stainless steels: AISI

414, AISI 304

� Wear protection of

conveyor coils in tungsten

carbide

� Wear protection

(interchangeable) of

conveyor diffuser

� Fixed differential speed

variation

STANDARDFEATURES

The electronic ROTOVARIATOR

is designed and manufactured

by the Pieralisi Group and

patented worldwide for

application on Pieralisi

decanter centrifuges of the

FP 600, JUMBO, HERCULES,

MAMMOTH and GIANT series

including already installed

decanters. The electronic

ROTOVARIATOR can be fitted

to Pieralisi decanter

centrifuges being used for

both sludge dewatering and

any separation process of a

solid from one or two liquids.Rotovariator

Thanks to the electronic

ROTOVARIATOR device it is

possible to:

� continuously vary the number

of screw revolutions in

relation to the bowl of the

decanter

� regulate the torque on the

decanter reduction gear to

the maximum levels allowed;

this allows to protect

transmission gears and to

adjust the rate of feed flow to

the decanter and/or the

screw differential speed.

THE ROTOVARIATOR

� Conveyor and bowl in AISI

316/Duplex stainless

steel

� Selection of optimum

conveyor and bowl design

OPTIONAL VARIATIONSFOR SPECIALAPPLICATIONS

interchangeable sintered

tungsten carbide segments

� Automatic differential

speed variation:

- via Rotovariator system

- other systems on request.
