Mechanical shaft seal for suspensions

Reliable sealing performance
Featuring a pair of product-side seal rings that extend into the vessel, the ESD44 delivers reliable sealing of abrasive suspensions and sticky media, especially in submerged or side-entry configurations.

Sterile sealing option for demanding applications
For applications with higher hygienic or sterile requirements, the ESD44S variant offers a sterile seal design. It is suitable for use in any orientation and allows for thorough cleaning and sterilization, making it an ideal choice for sensitive processes.

Robust, hygienic design
The ESD44 is constructed with smooth surfaces and a solid geometry that minimizes crevices and dead spaces. This ensures thorough cleanability and reduces the risk of contamination, an essential feature for hygienic applications.

Suitable for multiple industries
This seal is particularly well suited for specialty chemicals and formulated consumer products, where both reliable sealing and hygienic design are essential.

Double-acting seals for mixing applications
Double-acting, liquid-lubricated mechanical seals like the ESD44 are the most common type used in mixing applications. They are versatile and effective across a wide range of operating conditions in mixing vessels.
The ESD44 can also be configured as a gas-lubricated version, where a continuous gas flow maintains a minimal gap to prevent wear on the seal faces.
