Pusher Seals
Flowserve Allpac 682 Pusher Seal
Allpac 682 mechanical seals work to significantly increase pump reliability in dirty and contaminated applications by protecting dynamic design mechanisms.
Solids: Up to 20%
API 682: Fully compliant
Pressure: Up to 730 psi
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.
