Sealless Mag-Drive Pumps - Griswold
Sealless magnetic drive pumps transfer fluids without a mechanical seal, so there are no leaks. A magnetic coupling transmits torque through a sealed containment shell, keeping hazardous fluids fully contained.
...
Metallic sealless mag-drive centrifugal pumps use a magnetic coupling to drive the impeller through a sealed containment shell, so there's no mechanical seal to leak. They're ideal for hazardous, toxic, flammable and expensive fluids where leaks are unacceptable.
Key Features
- Leak-free design – eliminates seal leaks and emissions
- Stainless and alloy construction – higher pressures and temperatures than plastic
- ANSI and ISO dimensions – drop-in replacement for sealed pumps
- Low maintenance – no seal flush systems or seal replacements
Application Considerations
Mag-drive pumps don't tolerate dry running or large solids, so protect them with power monitors and strainers. Size for viscosity, temperature and specific gravity, which affect magnet coupling torque.
Centro can help you select metallic mag-drive pumps for safe, leak-free chemical transfer.

- A sealless mag drive pump uses magnetic coupling instead of a mechanical seal to transfer torque from the motor to the impeller. This creates a fully sealed pumping chamber that eliminates leakage and reduces maintenance.
- Mag drive pumps offer zero leakage, excellent chemical resistance, low maintenance, and enhanced safety for hazardous or expensive fluids. They also prevent emissions and environmental contamination.
- Common applications include chemical processing, pharmaceuticals, water treatment, semiconductor manufacturing, plating, oil and gas, and any process requiring leak free fluid transfer.
- Common constructions include polypropylene (PP), PVDF, stainless steel, and alloy materials. Internals may include ceramic, carbon, or silicon carbide components to support chemical resistance and durability.
- Yes. Mag drive pumps often operate efficiently due to fewer mechanical losses and inline designs. Operating close to the pump’s Best Efficiency Point (BEP) improves energy performance and pump life.
