Double-acting mechanical shaft seal

For medium-pressure applications
Featuring a back-to-back arrangement of two identical seal ring pairs, the ESD34G is designed for medium-pressure applications up to 40 bar (abs).
Its reliable dual-seal configuration ensures optimal performance even under fluctuating or dynamic process conditions.

Modular design for maximum flexibility
The ESD34G benefits from a modular design that allows for easy adaptation to a wide variety of process requirements.
Temperature control can be achieved either through a temporary heat trap for cooling or via a water jacket on the bearing housing, making this seal highly adaptable.

Durable construction for long-term cost savings
The ESD34G is built for robustness, helping reduce long-term operating costs.
Finite Element Analysis (FEA) is applied to ensure optimized stress distribution across each seal ring.
In addition, the seal incorporates specially engineered spring designs to maintain consistent preload forces, even under significant agitator shaft deflection.

Minimal leakage in extreme conditions
This seal delivers near-zero leakage, even under the harshest operating conditions.
It is particularly well suited for demanding industries such as hydrometallurgy and is engineered to meet the highest standards of sealing reliability.

A proven choice for mixing applications
Double-acting, liquid-lubricated mechanical seals like the ESD34G are the most commonly used sealing solution for mixing vessels.
They offer exceptional performance across a wide range of operating environments.
The ESD34G is also available in a gas-lubricated version, where a continuous gas supply maintains a micro-gap between seal faces to minimize friction and wear.
