API Mechanical Seal Concepts and EN12756-Based Solutions for Industrial Pump Sealing

Generally the highest criticality (critical, long-term) use for an API mechanical seal is in a pump application. For standard industrial applications, EN12756 compliant mechanical seals are typically easier to design and install than API mechanical seals and provide dependable methods of sealing the shaft, even in lower criticality applications (Water, Oil, etc.).

Advantages of API Mechanical Seal

EN12756 Standardized Dimensions

Meets EN12756 standard dimensional requirements, which is a suitable alternative in place of API pumps systems.

Flexible Material Selection

Offers flexibility in selecting materials through varying combinations of seal face material and elastomers to meet different Media properties.

Simplified Seal Configuration

Simplified seal configuration will reduce complexity of the system compared to traditional API seals.

API Mechanical Seal

Application Scenarios

API 682 seal plans labelled to be in accordance with API 682 for Chemical Process, Petrochemical and Refinery applications. Mechanical Seals Listed to API 682 are engineered to meet the industry's performance requirements for Pressure (temperature), with compatibility to multiple media. Because of extreme service conditions (Centrifugal And Process Pump) Mechanical Seal Plans for API682's provide lubrication, cooling and pressure regulation for Mechanical Seals. Mechanical Seals listed to API682 are also suitable for Hazardous and Critical Applications, so as to minimize the chance of leakage and reduce operational risks. In addition, these Mechanical Seals are manufactured to International Safety Standards, to facilitate compliance.

FAQ

Is this an API 682 certified seal?

No, it meets EN12756 and GB/T 6556.
Only in those systems that do not require API compliance (due to website language).
Yes, as it is available under both Basic Flushing and Cooling plans.
It is designed for general industrial and chemical centrifugal pump applications.
