VIEW OUR SEAL LINE

 

AST manufactures a complete line of cartridge and component mechanical seals for process pumps. The AST70 single cartridge seal has become the standard for harsh applications. The AST80 dual cartridge seal incorporates liquid shear pumping to remove heat from the seal faces and can be operated with a pressurized barrier or non-pressurized buffer fluid system. All AST seals are field-rebuildable, giving pump users control over their schedule and budget.

AST will respond to your inquiry within minutes.
