Mag Drive Centrifugal Pump vs Industrial Centrifugal Pump

Mag Drive Centrifugal Pump Vs Industrial Centrifugal Pump

Stuck between a Mag Drive and a Standard Centrifugal Pump? Don’t spend time trying to compare, we’ve got you covered! Have a read of our article comparing the two pumps to help you decide what you need, and whilst you’re at it, check out our post on Centrifugal Pumps: Everything You Need To Know!

The main difference between Tapflo’s Magnetically Driven Centrifugal Pump and Industrial Centrifugal Pump is how the power and speed from their motors are transmitted to the impeller. The CTM is magnetically driven, meaning that the motor shaft is connected to a magnetic coupling which has the impeller attached to it. The magnets installed on the drive magnet and impeller/magnet assemblies have different polarities which means when the motor shaft turns, it then forces the impeller magnet assembly to rotate within the pump volute. As there is no physical connection between the motor shaft and impeller assembly, the process fluid is retained within the pump head, therefore guaranteeing leak-free operation.
Our Industrial Centrifugal Pump, on the other hand, has its impeller directly coupled to the motor shaft which has a mechanical seal attached to it to protect the motor from ingress of the process fluid, like a traditional Centrifugal Pump. Although the pumps are quite similar in many aspects of their design and applications, there are some key differences to note when choosing your Tapflo Centrifugal Pump.

Magnetically Driven Centrifugal Pump Industrial Centrifugal Pump

Differences in Design

Our Magnetically Driven and Industrial Pumps are both Close-Coupled Centrifugal Pumps that can be supplied with either semi-open or closed impellers, whilst the Industrial Centrifugal Pump is also available with an open impeller for solids handling up to 6mm. Both of these compact pumps are ideal for applications requiring high mechanical and corrosion resistance, as the CTM is manufactured from Glass Fibre reinforced Polypropylene or PVDF, and the CTI is manufactured from Glass blasted Stainless Steel AISI 316L.

The Magnetically Driven Centrifugal also has the added benefit of all wetted components being manufactured from non-metallic injection moulded thermoplastics, which strengthens the excellent corrosion resistance of the pump. Designed with reliable Tapflo technology, the CTI and CTM (and other Tapflo Centrifugal Pumps) have fewer parts which ensure shorter downtimes and less maintenance.

Another feature of Tapflo’s Mag Drive is that it also has the added bonus of being a sealless pump, unlike the CTI that can be supplied with a variety of mechanical seals. Options include (but are not limited to) flushed seals which are recommended for applications involving sticky or abrasive fluids, or lubricated seals which are ideal for applications where there is a risk of dry running or the fluids solidifying within the pump. The benefit of the CTM being sealless means that it can be used within industries that need to reduce the risk of hazardous fluids leaking out of the pump, such as nuclear and chemical industries. This also means that there is no need for resins or glues to be used within the pump’s design, so the Mag Drive Pump can perform better and safer at higher temperatures.


These pumps are typically used for:

  • Tank cleaning
  • Tank to tank transfer
  • Dispensing
  • Pressure boosting
  • Loading
  • Offloading
  • Metering
  • Batching

They can also be used with Tapflo’s extensive range of control accessories, for example, the CTI can be fitted with a heating or cooling jacket.

The Industrial Centrifugal Pump can be used for applications including:

  • Mild chemicals and solvents
  • Oils
  • Lubricants
  • Coolants
  • Detergents
  • Partially solid laden fluids
  • Water transfer

The CTI can also be ATEX rated to allow it to be used for pumping diesel, petrol and Kerosene. The CTM can be used for applications specifically involving clean and thin liquids, such as alkalis and acids, or pure chemicals. For the full list of potential applications for the CTI Industrial Centrifugal Pump and CTM Magnetically Driven Centrifugal Pump, please visit their product pages.

Alternatively, Tapflo UK offers many other series’ of Centrifugal Pumps which can be accessed via our website, including the rest of our Tapflo range, Salvatore Robuschi Centrifugal Pumps or BBA Pumps’ Self-Priming Centrifugal Pump range.

The main factor when choosing your pump should always be the product you are pumping; which pump will suit your application best? It is always best to consult an expert to ensure you’re choosing the right pump for your specific application. Alternatively, you can visit our Centrifugal Pump FAQ page.
