Liquid-lubricated mechanical shaft seal

Reliable sealing and structural strength
Equipped with four geometrically identical mechanical seal rings, the ESD64G ensures dependable sealing performance and exceptional mechanical robustness, even in large-scale configurations.

Efficient cooling and resistance to pressure fluctuations
This mechanical seal features an integrated short heat trap for effective cooling and can optionally be equipped with a water jacket for enhanced temperature control.
Designed to withstand pressure surges and shaft deflection without deformation, the ESD64G ensures stable and consistent operation under fluctuating conditions.

Excellent heat dissipation and minimal leakage
Thanks to its thermally optimized design, the ESD64G is ideal for high-temperature processes. The seal maintains minimal leakage even under challenging operating conditions, significantly extending service life and ensuring operational reliability.

Ideal for bulk chemicals, polymers, and hydrometallurgy
This seal is particularly well suited for demanding industries that process bulk chemicals, polymers, specialty chemicals, sterile products, and in hydrometallurgical applications.
Its design prioritizes durability and high sealing performance in large-diameter setups.

Double-acting seals for mixing applications
Double-acting, liquid-lubricated mechanical seals like the ESD64G are the most common sealing solution for mixing vessels. Their versatility makes them suitable for nearly all operating conditions.
Alternatively, they can be configured as gas-lubricated versions, where a continuous gas flow maintains a fine gap between seal faces, reducing wear and extending lifespan.
