Sedimenting Centrifuges
Centrifugal sedimentation solutions provide efficient separation of even the finest solids & near complete clarification of liquid phases.
Hybrid Centrifuges
Combines filtering and sedimenting centrifuges into a hybrid machine for increasing solids dewatering efficiency and reduced energy costs.
Laboratory Centrifuge
Centriflab and Centriflex are purpose-designed lab centrifuges for solid/liquid separation test work, supporting scale-up to commercial centrifugal separators.
Centrifugal separators engineered for your application
Multotec’s range of centrifugal separators includes solutions for filtration and sedimentation, as well as a range of hybrid machines, which combine the two processes.
In collaboration with SIEBTECHNIK TEMA, Multotec provides customers with customised centrifugal separators for their application requirements. Using an excellent range of product data and designs developed over decades of industry experience, we provide purpose-driven solutions made to fit your plant.
Our centrifugal separators are compact, meaning they can easily be installed for retrofit and greenfield projects.

Achieve Zero Liquid Discharge (ZLD)
Stringent environmental legislation and requirements for ISO 14001 compliance have placed a focus on companies to reduce and process their waste more efficiently, aiming towards zero liquid discharge.
The application of centrifugal separators extends beyond water removal from slurries; it also facilitates the isolation of marketable materials, helping add streams of revenue for businesses.
The SIEBTECHNIK TEMA Conturbex centrifuge, with more than 7 000 machines currently operating in more than 1 000 applications across the world, is the ideal equipment for ZLD processes, offering specific advantages over pusher centrifuges for this application:
- Designed for short product residence time means performance is not impacted by fluctuating flow rate or solids concentration
- Engineered with a scrolled product transporting mechanism that allows even distribution of product along the basket, reducing vibrations and ensuring mechanical integrity of the machine
- Self-cleaning design, especially useful in unplanned outages where rotating components slow down and simultaneously clean the basket
- Suitable for any slurries, including abrasive, corrosive or extreme temperatures, ensuring durability and increased component life

Our longest-standing centrifugal separators
The SIEBTECHNIK TEMA screen roll centrifuge and vibrating screen centrifuge are the 2 longest standing centrifuges offered by Multotec.
The first SIEBTECHNIK TEMA vertical screen scroll centrifuge for industrial applications was developed in 1938, and the first horizontal centrifuge developed in 1954 with the name CONTURBEX. Today there are thousands of these centrifugal screening machines in use worldwide.
SIEBTECHNIK TEMA vibrating centrifugal separators have been successfully used for dewatering coal since 1965 and are reliable coarse coal centrifuges.

Frequently asked questions
What is the principle of centrifugal separation?
Centrifugal separation functions by utilising accelerated sedimentation and employs centrifugal force to distinguish components in a mixture based on their density differences. When rapidly spun, the stronger outward force pushes denser components outwards, while lighter components stay nearer the centre. This enhances natural settling, enabling quick, efficient separation of different phases: liquid-solid, liquid-liquid, or gas-solid.
How do centrifugal separators work?
Centrifugal separators rapidly spin a mixture, generating powerful centrifugal force (much stronger than gravity). This force pushes denser components outwards and lighter components inwards, allowing accelerated separation of distinct layers or phases based on density differences, which are then collected.
What is the difference between a filter and centrifugal separators?
A filter separates by using a physical barrier (porous medium) to block particles larger than its pores, primarily based on particle size. A centrifugal separator, conversely, spins the mixture to generate powerful centrifugal force, separating components based on density differences without a physical filter medium.
What are the advantages of centrifugal separation?
Centrifugal separation is highly effective and versatile due to several key advantages: it offers high separation efficiency for even fine particles, boasts significantly faster processing speeds than gravity, leads to lower long-term operating costs by eliminating consumable filter media, and demonstrates broad versatility across various mixture types and industries.
