agitator mechanical seal design factory

Unlike, pumps, a tank mixer is generally not designed to a standard. The exception to this is in Germany where the DIN standards are prevalent on process reactors. Greater pressure fluctuations are prevalent up to pressure reversal situations.

This is best illustrated by the Flowserve standard cartridge seal. This was originally designed as a pump seal. It was then modified to be able to operate as a mixer seal (ISC2-MW). The main difference is that the mixer version is designed to work with increased run-out associated with mixers.

– Cleaning – a mechanical seal for agitator is generally run during CIP (Clean In Place) at low speeds. A mechanical seal can be SIP’d internally for sterilisation.

We supply mechanical seals for agitators & tank mixers to the pharmaceutical, bio-pharma, chemical processing, mineral and ore processing and general industries.

The first choice for ultra-clean pharmaceutical and biotechnology applications, Type 5280 vessel seals apply Qualified Hygienic Design (QHD) and GMP standards and guidelines to enable the cleaning and sterilization of the product wetted process area with the seal in place (CIP, SIP). Due to the rotating seat design, the inboard sealing components protrude into the vessel, making them accessible for cleaning and/or sterilization devices installed in the reaction vessel. To avoid recontamination of the process vessel via the applied barrier fluid, a steam sterilization of the seal"s barrier room is feasible on request. The rotating seat design allows for application to top, side, or bottom entry mixers or agitators as well as products with a higher viscosity or solid content. This makes the seals a perfect solution for special equipment such as dryers or process filters.

Due to their modular design concept, Type 5280 seals are available in liquid-lubricated (5280 W), gas-lubricated (5280 G) and dry-running (5280 D) versions as well as a unique gas/dry face combination (5280 GD). Advantages of contacting dry-running seals include freedom from contamination by barrier liquid and a low face wear rate together with a cost-efficient, easy-to-install (gas) supply system. Advantages of gas-lubricated versions (G, GD) include the non-contacting and wear- and particle-free operation. The GD design reduces the overall barrier gas consumption compared to G version.

Type 5280 is part of a seal family consisting of different seal types that are suitable for different vessel materials: Type 5280 for steel, Type 5281 for glass-lined and Type 5282 for special alloy vessels.

Mechanical seals have been used in agitator technology since 1950. EKATO is one of the pioneers, using mechanical seals in agitators and continues to produce them today. EKATO offers a wide range of robust seals and reliable accessories for cooling and supplying the seals with sealing medium. A distinction is made between dry-running and gas- and liquid-lubricated mechanical seals.

Double-acting liquid-lubricated mechanical seals are the most common type for mixing applications. These seals can be used under nearly all operating conditions in a mixing vessel. They can also be designed as a gas-lubricated version in which a continuous supply of gas into the seal chamber maintains a marginal gap, thus preventing wear of the seal rings.

Agitator or Reactor Mechanical Seals are specifically designed for Mixer, Agitator and Reactor applications, to combat the inevitably radial and / or axial shaft movement that occurs in these applications. Rota-Tech mechanical seals can be configured to operate wet, dry or with a gas barrier. Agitator & Reactor Mechanical Seals are available in a wide range of seal face, Elastomer and alloy combinations, to suit individual applications. Externally and Internally Mounted seal, well balanced faces and inclusion of steady bearings incorporates in many design features to increase seal life.Our Seals are a family of engineered and standard Mixer, Agitator & Reactor Seal Designs in different configurations for Top, Side and Bottom Entry installation.

Recently Lidering has incorporated to its catalogue a new LMS23 seal, designed and produced by our industrial engineers from the custom manufacturing section.

There is no mechanical seal design that is suitable for all applications. Specific material selection and design features must be thoroughly examined for each application.

Fortunately, there is a broad experience with the applications in these industries and it provides us with guidance for sealing in the most of applications.

However, as with any application, successful sealing can only occur if process conditions, state of the equipment, and cleaning/sterilization requirements are perfectly known.

An industrial agitator can be defined as any bulk processing equipment designed to mix or blend heterogeneous materials to form a homogeneous final product.

Mixers and agitators are present in around the world and are often used to mix foods, chemicals, pharmaceuticals, household products, plastics, and minerals.

Vertical agitators are a type of machinery with a spiral mixing tool that creates an upward flow of unmixed products at the periphery, as well as a downward flow of mixed products around the shaft.

This presents an important feature of the application. The fluid, which is at the bottom of the agitator, does not normally come into contact with the seal, therefore the seal cannot depend on the product fluid to guarantee its lubrication.

Another strong point of this mechanical seal is its balance. The special design of its friction faces allows it to withstand vacuum environments in the range up to 10 bar.

When developing new processes, the chemical engineer determines the basic conditions and recipes for the process. This laboratory data is generally not sufficient enough to design the production plant. The interaction of chemistry, physical parameters and instrumental boundary conditions in complex processes is usually determined in pilot plants. Chemical and bioreactions, crystallizations or mixing rheologically demanding media are investigated in these experimental plants. The concept of the future production plant must be considered while planning the pilot plant so that the geometrical circumstances, the residence time behavior as well as other parameters can later be extrapolated to the scale of the production plant.

In EKATO’s laboratories, a number of lab and pilot plants are available for carrying out such investigations. Typical batch processes can be run under normal industrial operating conditions and the range of available tank sizes starts from 5 up to 100 l. These can be for example hydrogenation reactions which are carried out at operating pressures of up to 100 bar. Therefore the mixing technology is designed in such a way that it can easily be extrapolated to production scale with regard to the design-relevant parameters such as mass and heat transfer, blend time and suspension of catalysts. Pilot plants are also available for the production of formulated products such as cosmetics, pharmaceutical products, paints and lacquers, adhesives, insulation materials and lubricants.

Seals come in all shapes and sizes. Always speak to a professional to ensure that the right seal is chosen for the job. User manuals for equipment may also list the correct replacement seal type. However, there are many to choose from so if unsure, do not guess.

From single to dual, there are six major types to consider.. For single seals these are: rotary external seals, mixer split seals or a mixer seals. For dual seals there are high viscosity cartridge seals, mixer cartridge seals or slow speed gas cartridge seals. Since a perfect fit is necessary, be sure to have the right seal in mind before making a choice.

Mixer seals are one of the strongest. Rough conditions that are typical for mixers can seriously damage the average seal. However, motion tolerance seals with the ability to shift automatically under pressure can withstand these harsh conditions. This is the only choice for a fully operational mixer. Cartridge, on the other hand, are not built specifically for mixers but rather for interchangeable use.

Sanitary seals are typically used for extra-large, heavy or hard to reach equipment. Most of these seals feature a split design so the equipment does not have to be dismantled to change out a seal. They are also self-lubricating since it is difficult to access the installed seals for maintenance. This keeps them from drying out and cracking. Single or double sanitary mixer seals are often available to meet a variety of needs. Some can be used interchangeably while some equipment requires only a specific seal and will not operate properly with a substitute.

Always make sure the correct replacement seal is chosen to avoid damaging the mixer or agitator and spending excess money to replace a seal an extra time. Most equipment will come with spare parts and seals are often on that list. Be sure to check the spare parts from the manufacturer before purchasing a new one. Also be sure to have a properly trained individual replace the old seal by installing a new one. Someone who is not familiar with the equipment and the installation process could damage both the seal and the mixer. The manufacturer is often able to send an expert to the site to install replacements for a fee if needed.
