الوصف

Allpac 682 mechanical seals work to significantly increase pump reliability in dirty and contaminated applications by protecting dynamic design mechanisms. Features and benefits: - Clean design with springs outside the process fluid prevents clogging and hang-up for applications with up to 20% solids. - Dual pressurized arrangement enables zero process emissions to optimally protect the environment and help facilities achieve decarbonization goals. - Thick cross-section seal faces are double-balanced for high barrier pressure operation and upset pressure reversals, ensuring seal faces always remain closed. - Outer seal options are available to provide the right level of performance capability and economy; all options maintain API 682 compliance and the correct level of barrier fluid circulation. - Engineered to retrofit into existing API 610 pump installations and resolve ongoing contamination challenges or can be specified in new, clean and/or dirty applications.
