Top entry agitators, also known as top entry mixers, are essential for various industrial mixing processes. These agitators are widely used in batch, continuous, and semi-continuous stirred tank applications, offering unmatched flexibility and efficiency in fluid mixing across multiple sectors.
Top entry agitators come with several sealing options tailored to the specific needs of different processes. The choice of sealing configuration ensures optimal fluid isolation and plant safety. Common sealing types include:
Open Tank Seal
Gland Packing Seal
Lip Seal
Vapour Seal
Single and Double Seals
Magnetic Seal
These sealing solutions are critical for maintaining process integrity and preventing contamination, especially in sensitive industries such as pharmaceuticals and food processing.
The material of construction for top entry agitators is chosen based on the process environment, including factors like chemical compatibility, corrosion resistance, and durability. Common materials include:
Stainless Steel
Inconel
Monel
Hastelloy
Duplex Steel
Titanium
Carbon Steel (with or without linings such as Rubber, FRP, PVDF, PTFE, Halar, etc.)
These materials ensure that the agitators can withstand harsh conditions, extending service life and reducing maintenance costs in demanding industrial environments.
Top entry agitators are used in a wide range of industries. Their versatility makes them ideal for mixing various substances, including liquids, slurries, and powders. Key industries include:
Chemical Processing
Minerals & Metals
Paints, Resins & Inks
Pharmaceuticals & Biotechnology
Food & Beverages
Sugar Processing
Wastewater Treatment Plants (WWTP)
These industries rely on top entry agitators for efficient mixing, blending, and emulsification to meet the stringent standards required in their respective fields.
A typical top entry agitator consists of a motor connected to a gear reducer, providing the necessary torque for mixing. The motor is connected to the agitator shaft, which is sealed to prevent leakage and protect the system. Depending on the process, the agitator can be equipped with one or more impellers to create the desired flow within the tank. The impeller design and rotation speed are selected based on the specific needs of the application.
In addition to vertical mounting, top entry agitators can also be installed off-center or inclined, depending on the tank design and mixing requirements. Some top entry agitators are even directly motor-driven, bypassing the need for a gear reducer.
The mechanical components, such as bearings, shaft size, and couplings, are selected based on the type of fluid being processed and the required mixing intensity. In some cases, custom agitators can be designed with specific configurations to meet unique processing requirements.
