Magnetic-driven pumps or Mag-drive pumps are popularly known as sealless pumps. They are the top option in applications where leaks cannot be tolerated. These include processes that use aggressive liquids like acids, alkalis, toxics, pollutants, corrosives, and other fluids that pose great risk to people and the environment when leaked. 

Another important function of mag-drive pump is moving difficult liquids. Some process fluids crystallize on seal faces and cause seal failures in sealed pumps. To resolve this problem, sealed pumps are installed with a flush system which makes the system more costly to maintain. In such case, a mag-drive pump is a better equipment to use.

On the other hand, mag-drive pumps cannot be used in applications that have limited power ratings and in processes that deal with solid-laden liquids.

Mag Drive Pump Design

As its name implies, mag-drive pumps are close coupled to the motor and doesn’t use a shaft to rotate the impeller. Instead, a magnetic drive is attached to the motor shaft while the impeller is fixed on another magnet. As the drive magnet spins, so does the impeller. This way, the need for any kind of shaft seal is eliminated. Consequently, risks of leakage are eliminated. 

It’s also worth noting that the only part that touches the product is the impeller. So, apart from the no-leak advantage, risks of contaminating the product are also minimal.

Finally, mag-drive pumps are the excellent choice in applications involving expensive, flammable, toxic, corrosive, or environmentally hazardous fluids.


Mag Drive Pumps Operation

The attraction between the drive magnet and the impeller magnet that starts the operation of the pump. Both shaft and impeller spin at the same time and speed. The normal operation of a centrifugal pump then takes place.


Mag Drive Pump Benefits

Traditionally, Mag drive pumps would be used on clean fluids with little or no solids.

  • Total leak-free design unless pump case is broken.
  • Minimal monitoring required because of its seamless design.
  • Most mag-drive pumps manufactured today can last up to 20 years without the need for overhaul.
  • No cooling required as they are close-coupled with the motor, hence the alignment of the pump and motor is unaffected by temperature rise.


At All Pumps, we have a range of mag-drive pumps from the best manufacturers and brands trusted by industries worldwide. Connect with one of our pump experts and we will help you find compatible equipment for your system.

A magnetic drive pump uses a balanced magnetic field to create the rotation of the fluid impeller. Unlike a traditional centrifugal pump which has a direct drive connection between impeller and motor, a mag-drive pump eliminates the direct drive mechanism and replaces it with a magnetic field.

All Pumps has extensive knowledge in supplying and servicing magnetic drive pumps such as FTI, which All Pumps is the sole importer and distributor.

Superior Quality Construction High Flow Mag Drive Pump. Runs Dry For Hours Without Damaging

Finish Thompson, Inc. is a well-known manufacturer of industrial pump systems that are made with state-of-the-art engineering. Based in the U.S., FTI uses a world-class manufacturing facility to ensure that each pump is made under the best conditions. The FTI product line of pumps ranges from drum pumps to centrifugal pump, vertical pumps, and magnetic drive pumps. 

Among the most in-demand products of FTI is its Mag-Drive Pump range. These equipment are constructed using superior quality materials so it can withstand different types of fluid used in various industries. To that note, the Mag Drive Pump series by FTI is, in fact, considered one of the most efficient chemical pumps available in the market. 

Carefully Engineered

The FTI mag drive pumps feature carbon bushings, which let the pumps run dry for hours without damage. They are equipped with neodymium magnets, which are the most powerful available‚ delivering direct-drive performance in a mag drive pump. And thanks to these completely encapsulated magnets and the vapor barrier between the wet end and motor adapter‚ the pump components remain unaffected by corrosive vapors in harsh environments making the FTI Mag Drive Pumps more durable than its competitors.

FTI strategically uses ceramic shaft and TEFC motor for it pump system. The Mag Drive range is constructed of polypropylene w/ EPDM elastomer. With its solid build, the FTI mag drive pump can be used in a couple of areas in ethanol plants and other applications that deal with flammable liquid. 

The FTI Mag Drive Pump Range includes:

  • DB Series Plastic Mag Drive Pumps
  • MSDB Series Plastic Mag Drive Pumps
  • SP Series Self Priming Mag Drive Pumps
  • UC Series Heavy Duty Mag Drive ANSIPump
  • MSKC Series Multistage Mag Drive Pumps
  • KC Series
