Disc stack separator

Used Disc Stack Separators for Industrial Separation 

A disc stack separator, also known as a disc stack centrifuge or centrifugal separator, is used to separate solids from liquids or to separate two liquid phases with different densities. The technology is widely used in industries where high separation efficiency, continuous operation, and reliable process performance are essential. 

At G-Force AB, we focus on used, refurbished, and reconditioned separators from well-known industrial brands, including Alfa Laval. Our stock changes over time, but we can often help customers source specific models even when they are not currently listed online. 

Our disc stack separators are suitable for a wide range of applications, including clarification, purification, liquid-liquid separation, solids removal, and process liquid treatment.

What Is a Disc Stack Separator? 

A disc stack separator is a high-speed centrifugal separator designed to separate different phases in a liquid process. Inside the separator bowl, a stack of conical discs increases the separation area, making it possible to separate fine particles or liquid phases efficiently. 

When the liquid enters the rotating bowl, centrifugal force pushes heavier components outward while lighter components move toward the centre. Depending on the separator design, the machine can be used for clarification, purification, or concentration. 

Disc stack separators are commonly used when a high degree of separation is required and when the particles or liquid phases are too fine for simpler mechanical separation methods. 

2-Phase and 3-Phase Disc Stack Separators 

Disc stack separators are commonly divided into 2-phase and 3-phase separation, depending on the process requirements. 

2-Phase Disc Stack Separators 

A 2-phase disc stack separator is typically used to separate solids from one liquid phase. This process is often called clarification. The machine removes suspended solids, fine particles, or impurities from the liquid, producing a cleaner output stream. 

Typical 2-phase applications include: 

• Clarification of process liquids 

• Solids removal from food and beverage products 

• Treatment of industrial liquids 

• Separation of fine particles from oil- or water-based fluids 

3-Phase Disc Stack Separators 

A 3-phase disc stack separator is used to separate two liquid phases with different densities, often while also removing solids. This is commonly used in applications where oil, water, and solids need to be separated in one continuous process. 

Typical 3-phase applications include: 

• Oil purification 

• Marine and fuel treatment 

• Edible oil processing 

• Liquid-liquid-solid separation 

• Process recovery and purification 

If you are unsure whether your application requires 2-phase or 3-phase separation, G-Force can help evaluate your process and recommend a suitable separator type. 

Common Applications for Disc Stack Separators 

Disc stack separators are used across many industries where liquid separation quality is critical. G-Force AB works with customers in several process industries and can help match the right separator to the application. 

Food and Beverage 

Disc stack separators are often used for clarification, purification, and solids removal in food and beverage production. Common applications include juice, beer, wine, edible oils, fermentation liquids, and other process streams where product quality and hygiene are important. 

Dairy Processing 

In dairy applications, centrifugal separators are used for milk clarification, cream separation, bacteria removal, and other process steps where controlled separation is required. Used and refurbished Alfa Laval separators can be an attractive option for dairy producers looking for reliable equipment at a lower investment cost. 

Oil and Marine Applications 

Disc stack separators are widely used for oil purification, fuel treatment, lube oil cleaning, and water removal. In marine and industrial oil applications, reliable separation helps protect equipment, improve process stability, and reduce contamination. 

Chemical and Industrial Processing 

In chemical and process industries, disc stack centrifuges are used to separate fine solids, recover valuable liquids, purify process streams, and improve product consistency. The right separator setup depends on flow rate, density difference, solids content, viscosity, and operating conditions. 

Wastewater and Process Water 

Disc stack separators can also be used in selected wastewater and process water applications where fine solids or oil contamination need to be removed from a liquid stream. 

Why Choose a Refurbished Disc Stack Separator? 

A refurbished disc stack separator can be a cost-effective alternative to buying new equipment. For many industrial applications, a properly inspected and reconditioned separator can deliver strong performance while reducing both investment cost and lead time.

Buy, Rent, or Source a Disc Stack Separator 

Different projects require different solutions. Some customers need a separator for long-term production, while others need equipment for testing, temporary capacity, or a specific project. 

G-Force AB can help you evaluate whether buying, renting, or sourcing a separator is the best option for your process. 

Buy 

Buying a used or refurbished disc stack separator is often suitable when the separation process is already defined and the machine will be used continuously in production. 

Rent 

Rental can be a good option for temporary production needs, pilot projects, testing, or when you want to evaluate a process before investing in equipment. 

Source 

If you need a specific model, brand, or capacity that is not currently in stock, G-Force may be able to help source the right machine through our network. 

Tell us what you need to separate, your required capacity, and your preferred timeline, and we will help you find a suitable solution. 

How to Choose the Right Disc Stack Separator 

Choosing the right separator depends on both the product and the process. Before recommending a machine, several technical factors need to be considered. 

Important selection factors include: 

• Liquid type 

• Flow rate 

• Solids content 

• Particle size 

• Density difference between phases 

• Viscosity 

• Temperature 

• Cleaning requirements 

• Desired output quality 

• 2-phase or 3-phase separation 

• Required automation level 

• Available installation space 

If you do not have all technical data available, G-Force can still help you start the evaluation. In many cases, testing or pilot-scale analysis can provide valuable information before choosing a separator.
