Flexaseal Engineered Seals and Systems

Flexaseal Engineered Seals and Systems provides high-performance mechanical seals and engineered support systems tailored to the needs of the water and wastewater treatment industries. We serve municipalities, OEMs, industrial facilities, and maintenance contractors with reliable sealing solutions designed to keep critical rotating equipment running with minimal downtime.

Our product offering includes NSF/ANSI 61 certified single cartridge seals, split cartridge seals, and other standard and custom mechanical seals for potable water and wastewater applications. Flexaseal’s split seal technology is particularly well suited for large pumps and difficult-to-access equipment, helping maintenance teams reduce installation time and avoid disassembling surrounding components. Our seals are engineered to perform in harsh environments with corrosive, abrasive, or solids-laden fluids—common in primary treatment, sludge handling, chemical dosing, and clean water systems.

Flexaseal manufactures at our facilities in the United States, with in-house engineering, machining, and testing capabilities that allow us to deliver responsive service, fast lead times, and customized solutions when needed. Our U.S. manufacturing presence supports a high standard of quality and dependable supply for customers across North America.

With a strong focus on reliability, uptime, and long-term performance, Flexaseal partners with water and wastewater professionals to solve sealing challenges and support the essential infrastructure that communities rely on every day.
