Sealless, Magnetic Drive Pump Launched by Flowserve

Flowserve Corporation launched the Innomag TB-Mag Dual Drive sealless pump to eliminate leaks, and protect workers, setting a new standard for safety and environmental protection that the company says is the first of its kind.

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. 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 new pump also has an additional layer of corrosion resistance for handling chemicals due to a nonmetallic liner that coats the pump internally, helping ensure leak elimination and creating a safety net for operators who process these fluids. And with only one bearing set, the pump is low maintenance.

The new pump offers all the same benefits as other similar products: ISO/ASME (ANSI) compliant, simple installation that doesn’t require specialty tools, low maintenance, solids handling up to 30% volume concentration. Due to its modular design, the pump can be enhanced by bolting on the dual drive unit or it is available as a complete unit.
