Flowserve launches world’s first sealless pump with true secondary containment

Flowserve Corporation has launched the Innomag TB-Mag Dual Drive Pump, the world’s first sealless pump to eliminate leaks, setting a new standard for safety and environmental protection.

The Innomag TB-Mag Dual Drive Pump is the world's only magnetic drive pump that is double hermetically sealed and features a secondary independent containment system to reduce impact from failures.

For chemical plant operators, processing toxic and hazardous fluids such as hydrofluoric acid or acrylonitrile requires safeguards to avoid potential catastrophic consequences for the sites and the environment around them. One such safeguard is using pumps with a secondary containment system to house liquid in the event of a pump failure. Historically, canned motor pumps (CMPs) were the only viable option because sealless pumps with dual control systems include parts that wear over time and are susceptible to leaking.

The Innomag TB-Mag Dual Drive now makes sealless pumps a safe alternative to CMPs and other sealless pumps with dual control systems because the liquid and drive sections of the pump are both sealed airtight, providing a true secondary layer of protection in the pump. By containing the liquid in the pump, the motor remains liquid-free and operational – the most common downfall from CMP failures. The Innomag TB-Mag Dual Drive also has an additional layer of corrosion resistance for handling chemicals due to a non-metallic liner which coats the pump internally.

These features help ensure the elimination of leaks, enabling a significant safety net for operators who process these fluids each day.

“Safety is one of our core values, and it was imperative for us to develop a pump solution that reduces the inherent dangers of working with hazardous chemicals and materials for our customers,” said Lamar Duhon, president of Flowserve Pumps Division.

“We’re excited to launch the Innomag TB-Mag Dual Drive, the latest novel addition to the Flowserve’s growing Innomag portfolio,” Duhon continued. “This innovation helps diversify our pump portfolio in support of Flowserve’s 3D strategy of diversification, decarbonization and digitization.”

The Innomag TB-Mag Dual Drive pump offers all the same benefits as other similar products: ISO/ASME (ANSI) compliant, simple installation, low-maintenance, solids handlings up to 30% volume concentration and reliability. With its modular design, standard single containment Innomag TB-Mag pumps can be enhanced by bolting on the Dual Drive unit. Alternatively, the Innomag TB-Mag Dual Drive can be purchased as a complete unit.
