Sealless Mag-Drive Pumps - Durco Flowserve
Sealless magnetic drive pumps are a type of pump that uses magnets to drive the impeller rather than a sealed shaft and bearings. This design eliminates the need for a mechanical seal, making them ideal for use in ...
Non-metallic centrifugal seal-less mag-drive pumps offer leak-free, corrosion-resistant fluid handling for aggressive chemicals, acids, and solvents in industrial applications such as chemical processing, water treatment, and electronics manufacturing. Utilizing a magnetic drive system instead of mechanical seals, these pumps eliminate seal failure risks and minimize maintenance in hazardous or high-purity environments. Constructed from materials like polypropylene or PVDF, they provide reliable, safe, and efficient operation where metal pumps may corrode or contaminate process fluids.
Metallic mag-drive gear pumps deliver precise, leak-free transfer of corrosive, viscous, or hazardous fluids in demanding industrial applications such as chemical processing, oil and gas, and specialty coatings. Featuring a seal-less magnetic drive design, these pumps eliminate the risk of emissions and mechanical seal failures while providing accurate, pulseless flow. Constructed from robust metals like stainless steel or Hastelloy, they offer high pressure capability, chemical resistance, and long service life in high-demand, high-integrity pumping environments.
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.

- 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.
