Allpac 682 Pusher Flowserve Cartridge Seal Dual Cartridge Slurry Pump Seal OEM

Flowserve Allpac 682 Pusher Seal Dual Cartridge Mechanical Seals for Pumps

• Mechanical Seals
• Pump Seals
• Pusher Seals

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.
