Magnetically Coupled Pump Ensures Leak-Free Operation

NETZSCH Pumps & Systems has launched the NEMO^® MY Magnetically Coupled Pump, designed to provide hermetically sealed, leak-free fluid transfer for demanding industrial applications.

Context: Challenges with conventional sealing systems
In industrial pumping systems, mechanical seals are commonly used to prevent leakage. However, seal failure can result in fluid loss, safety risks, and environmental hazards—particularly when handling aggressive, toxic, or hazardous media.

Industries such as chemical processing, pharmaceuticals, and food production require reliable solutions that minimise leakage risks and ensure operational safety.

Technology: Magnetic coupling for hermetic sealing
The NEMO^® MY pump replaces conventional mechanical seals with a magnetic coupling system that transmits torque without physical contact between drive and pump chamber.

This design creates a fully hermetically sealed system, eliminating potential leakage paths and improving system integrity when handling sensitive or hazardous fluids.

Performance: Stable and versatile fluid handling
The pump is engineered to handle a wide range of fluid viscosities, from low-viscosity liquids to highly viscous and shear-sensitive materials. It delivers continuous, pressure-stable, and low-pulsation flow, supporting consistent process performance.

With the capability to handle viscosities up to 20,000 cps, the pump is suitable for demanding applications involving slurries and complex fluids.

Operational benefits: Reduced maintenance and improved safety
The magnetically coupled design eliminates the need for sealing pressure control and fluid level monitoring, reducing maintenance requirements and operational complexity.

The hermetic sealing enhances safety by preventing leaks of hazardous substances, making the pump suitable for use in regulated and safety-critical environments.

Compliance and applications
The pump is compliant with ATEX requirements, enabling safe operation in explosive atmospheres. It is suitable for applications across chemical, pharmaceutical, paint, and food industries.

Conclusion: Advancing safe fluid handling
With its magnetically coupled, hermetically sealed design, the NEMO^® MY pump addresses key challenges in fluid handling by improving safety, reliability, and maintenance efficiency. The solution supports industries requiring secure and consistent transport of complex and hazardous fluids.
