Are you responsible for operation or main-

tenance of a sugar-producing facility?

ANDRITZ develops and manufactures cen-

trifugal pumps that are used throughout the

sugar production process. Depending on

the area of the facility concerned, centrif-

ugal pumps with a closed, semi-open or

open impeller are used.

Wear-resistant and non-clogging pumps

are a prerequisite for trouble-free opera-

tion in the sugar industry. Pumps from the

ACP, ISO and S series with closed or open

impellers are used according to the flow

rate required, from beet washing to juice

purification and to crystallization. As the

sugar content increases as a result of juice

thickening and the gas content rises due to

centrifugation, the ANDRITZ AD centrifugal

pump can be used for syrup applications

without any difficulties.

A special feature is the combination of a

single-stage centrifugal pump with an in-

tegrated vacuum pump prevents any ac-

cumulations of air at the impeller inlet and

guarantees high priming performance by

the pump, even with unfavorable suction

pipe routing. The vacuum pump removes

the gas content in the medium in order to

ensure that the thick juice can be conveyed

without any difficulties. The pump is not

sensitive to high concentrations (at a sugar

content of up to 70%) as a result of the semi-

open impeller, which also provides higher

efficiency with viscous media compared to

closed impellers. As a result of these design

features, self-priming centrifugal pumps from

the AD series with integrated vacuum pump

are excellently suited to conveying thick juice

with a high air and sugar content at low in-

vestment cost and maintenance needs.

With the company‘s own technical center

ASTRÖ, we have an internationally recog-

nized institute for hydraulic development

and testing at our disposal. Optimization

on a computer using CFD and numerous

model tests result in the high economic

efficiency of the ACP, S, ISO, and AD

pump series.
