Mechanical Seals for Zero Leakage and Challenging Requirements 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. Double-acting mechanical seal liquid lubricated Function and application • Two identical pairs of seal rings in a back-to-back arrangement • Ideal mechanical seal for applications in the medium pressure range up to 40 bar (abs.) • Use of the modular design opens up many different extension options • Mechanical seal most commonly used in agitators worldwide • Deliverable with short heat trap for cooling • Deliverable with water jacket for cooling Advantages: • Life cycle cost savings due to extremely solid construction • Use of FEA ensures optimized stress distribution in every seal ring • Special spring designs ensure uniform pre-tensioned conditions even in cases of significant agitator shaft displacements • Almost zero-leakage under the roughest conditions Working limits: • Shaft size: 40...220 mm • Sliding speed: 0...5 m/s
