Mechanical shaft seal for low-pressure applications

Efficient cooling and modular design
The ESD34N can be equipped with a temporary heat trap for short-term cooling or a water jacket on the bearing housing, enabling effective temperature control during operation.
Designed with cost-efficiency in mind, the ESD34N features a modular construction with standardized wear parts to streamline spare parts management and reduce lifecycle costs.

Ideal for compact installation spaces and packing replacement
Thanks to its compact dimensions, the ESD34N is perfectly suited for installations with limited space.
It is also an ideal upgrade from traditional packing systems, offering improved sealing performance and reliability in low-pressure environments, resulting in reduced downtime and operating costs.

Suitable for mixing applications and demanding environments
The ESD34N is designed for a wide range of mixing applications, including bulk chemicals, polymers, pharmaceuticals, cosmetics, specialty chemicals, formulated consumer products, biofuels, and biorefineries, and storage tanks.
It ensures reliable operation with minimal leakage, even under challenging process conditions.

The go-to seal for mixing technology
Double-acting, liquid-lubricated mechanical seals such as the ESD34N are the most commonly used type in mixing applications.
They perform exceptionally well under nearly all conditions found in mixing vessels.
The ESD34N is also available in a gas-lubricated version, where a continuous gas supply maintains a micro-gap between seal faces to minimize wear and extend service life.
