Advanced Sealing Technology
Advanced Sealing Technology (AST) is a leading manufacturer of high quality and reliable engineered mechanical seals, components and accessories.
AST offers innovative solutions for pumps and other rotating equipment used in mission-critical applications across various industries, including oil and gas, power, chemical processing, pharmaceutical, food and beverage, steel, pulp and paper, marine, water and wastewater, and mining.
AST manufactures a complete line of cartridge and component mechanical seals for process pumps. The AST 70 single cartridge seal has become the standard for harsh applications.
The AST 80 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 (plan 52 and 53). All AST seals are field-rebuildable, giving pump users control over their schedule and budget.
