Magnetically coupled agitators for pressure vessels in industrial processes
A magnetic stirrer is used in process tanks and pressure vessels where liquids or process materials need to be mixed without traditional shaft penetration through the tank wall.
The stirring takes place via magnetic power transmission between an external drive and an internal rotor or stirrer depending on the design and application.
This type of solution is often used in processes where tightness, hygiene or minimized risk of leakage are important factors.
Process surplus offers both new and used stainless steel pressure vessels in stainless steel 304 and acid-proof 316 where magnetic coupled stirrers may be present depending on specification and application.
Function and structure
Magnetically coupled stirrers are used for mixing, homogenizing or circulating liquids in processes where traditional shaft seals are not desirable.
The design usually consists of an external motor unit and a magnetically coupled stirring system located inside the tank.
Since the power transmission is magnetic, no through shaft is needed through the tank wall, which can reduce the need for mechanical seals depending on the design and construction.
The tanks can also be equipped with, for example, level measurement, temperature-related solutions, CIP systems and inspection hatches depending on the specification and process requirements.
Materials and construction
Magnetically coupled stirrers and associated tanks are often manufactured in stainless steel 304 or acid-proof 316 depending on the properties of the liquid and the requirements of the process.
Stainless steel is used in many industrial applications where cleanability, hygiene and resistance to corrosion are relevant factors.
Tanks are usually welded and may have different surface treatments such as grinding or polishing depending on the application and requirements of the process.
Design features such as wall thickness, rotor design and agitation solution vary depending on the tank size, operating conditions and specification.
Pressurized and atmospheric solutions
Magnetically coupled stirrers are often found in pressurized tanks and pressure vessels depending on the process and application.
Tanks may be equipped with components such as safety valves and pressure gauges depending on the design and specification. Documentation linked to, for example, PED and CE may be available where indicated.
Atmospheric solutions are also available depending on process requirements and application.
Applications in industry
Magnetically coupled stirrers are used in several types of industrial processes.
Examples of applications include food production, chemical industry, pharmaceutical related processes and water purification where tightness, hygiene or controlled mixing can be important parts of the process.
The use varies depending on the fluid properties, temperature, pressure conditions and process requirements.
Technical options and equipment
Tanks with a magnetic stirrer can be equipped with, for example:
Magnetically coupled stirring systems
