Sealless Mag-Drive Pumps - Durco Flowserve
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.

Non-metallic mag-drive centrifugal pumps handle corrosive chemicals with no seal and no metal in contact with the fluid. Plastic and fluoropolymer construction resists acids, caustics and plating solutions.
Features
- Leak-free magnetic coupling – no seal to fail
- Polypropylene, PVDF and ETFE – broad chemical resistance
- Compact designs – OEM and process systems
- Low maintenance – no seal flush required
Choosing a Pump
Provide chemical, temperature, flow and head. Protect from dry running and solids. Non-metallic pumps have temperature limits, so verify for hot fluids.

Metallic mag-drive gear pumps combine the precise flow of gear pumps with leak-free magnetic drives. They're used for metering, transfer and circulation of viscous or hazardous liquids.
Features
- Precise, pulseless flow – metering and dosing
- Stainless and alloy construction – high pressures and temperatures
- Leak-free design – hazardous fluids
- Handles viscosity – oils, polymers and resins
Choosing a Pump
Provide flow, pressure, viscosity, temperature and fluid. Clean fluids are required, since solids damage gears. Pair with VFDs for flow control.

Industrial pumps move liquids from one place to another, whether you’re handling water, chemicals, or thick, heavy fluids. Most pumps fall into one of two main categories: positive-displacement pumps and centrifugal pumps (also called non-positive-displacement pumps).
Positive-displacement pumps move a set amount of liquid each cycle using seals or valves. They’re the go-to choice for thicker, high-viscosity materials—like slurries, oils, or adhesives—because they deliver a steady, reliable flow. Centrifugal pumps use rotating impellers to keep liquid moving, making them ideal for high-volume jobs like circulating water, solvents, chemicals, and light oils.
We carry a full range of industrial pumps to match almost any process or application. Our selection includes air-operated double diaphragm (AOD) pumps, lobe pumps, submersible pumps, hose/peristaltic pumps, metering pumps, progressive cavity pumps, sealless mag-drive pumps, hydraulic pumps, and a variety of pump control systems.
Whether you’re looking for precision metering, chemical compatibility, or rugged performance, our team can help you find the right pump for the job. Browse our pump categories to compare options, or call us for expert guidance on selecting the best pump for your operation.

- 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.
