Centrifuge Applications & Industry Uses
Used centrifuges are essential across industries where separation, clarification, or dewatering is required. Common applications include:
Chemical Processing: Separation of solids from liquid chemical streams
Food & Beverage: Clarification of oils, dairy products, and beverages
Pharmaceutical Manufacturing: Purification and separation of active compounds
Wastewater Treatment: Sludge dewatering and solids removal
Oil & Gas: Separation of oil, water, and solids in processing operations
These systems improve process efficiency, reduce waste, and enhance product quality.
Used Centrifuge Buying Considerations
When selecting a used centrifuge, it is important to evaluate both process requirements and equipment condition:
Separation Type: Solid-liquid vs. liquid-liquid vs. three-phase separation
Throughput Capacity: Match system size with production requirements
Operating Speed & G-Force: Determine separation efficiency and performance
Batch vs. Continuous Operation: Choose based on process workflow
Material Compatibility: Ensure construction matches process chemistry
Condition & Maintenance History: Review wear components and service records

Sell Your Used Centrifuges
Aaron Equipment actively purchases surplus centrifuges, including decanter, disc, and basket systems. Whether upgrading equipment or decommissioning assets, our team can help maximize value.
An industrial centrifuge is a machine that uses centrifugal force to separate materials based on density differences, commonly used for solid-liquid or liquid-liquid separation.
Common types include decanter centrifuges, disc centrifuges, basket centrifuges, and tricanter systems, each designed for specific separation applications.
Choosing the right centrifuge depends on material properties, separation type, throughput requirements, and whether batch or continuous operation is needed.
Yes. Used centrifuges are built for long service life and can remain highly reliable when properly maintained, inspected, and refurbished if necessary.
Centrifuges are used in chemical processing, food production, pharmaceuticals, wastewater treatment, and oil and gas industries.
