Magnetic Sealless Pumps: Technology That Reduces Lifetime Costs

magnetic sealless pumps

As the inventors of magnetic drive pumps, HMD have only ever manufactured magnetic sealless pumps since the beginning. Their superior experience, knowledge and design-reliability means that HMD/Kontro’s pump selection and application is unmatched in the industry today.

In recent years there has been a rise in the awareness of environmental, safety and maintenance issues in terms of process-fluid leakage. It’s a major concern particularly in chemical processing plants and municipal wastewater facilities. This is where magnetic sealless pumps can make all the difference.

What Is A Magnetic Sealless Pump?

Magnetic Drive refers to the coupling between the wet end of the pump and the motor.  In “direct drive” or “shaft sealed” pumps, the impeller of the pump is attached to the shaft of the motor, and this design depends on some form of dynamic seal to contain the pumped liquid. 

In a magnetic drive pump, the wet end and motor are two separate contained parts, connected by a housing that ensures concentricity between the two parts. At the end of the motor shaft, a ring of outer magnets is attached. Correspondingly a ring of inner magnets is attached to the internal pump shaft. The internal pump shaft is supported on plain bearings that are lubricated by the pumped liquid and has the impeller attached to the other end of the pump shaft.

Between the outer magnet and inner magnet rings is the stationary containment shell. This non-magnetic component contains the pumped liquid. The magnets in magnet rings are co-axially aligned and thus attract each other. This means as the electric motor rotates, the outer magnet ring and the inner magnet ring rotate at the same speed causing the impeller to rotate and the pump to operate. As the shaft of the motor does not extend into the interior of the pump, there is no need for a shaft seal, and without a shaft seal, the danger of leakage commonly associated with the shaft seal is eliminated.

Sealless versus Sealed Pumps

Mechanical seals, like bearings, are designed to maintain their sealing ability by purposefully leaking small amounts of fluid to keep the seal faces lubricated. The seal faces wear in the process and they lose their effectiveness and ultimately increase the liquid loss. This ‘leakage’ can reach the environment either as a liquid or vapor through a process referred to as fugitive emission. This can be very costly resulting in lost time, money and decreased workplace safety.

Seals in traditional pumps will ultimately fail and require expensive maintenance or replacement and therein lies the primary advantage of sealless magnetic drive pumps. They don’t leak which means fewer process inefficiencies, maximized output and minimized risk from hazardous and volatile materials. Possibly the greatest advantage of sealless pumps is that there is no downtime. Without having to constantly service, repair or replace seals, companies save considerably on time, effort and money. 

Watch this short video for a closer look at the Basics of a Magnetic Drive Pump.

Inside A Magnetic Sealless Pump

The magnetic centrifugal pump flows at approximately 1,000 gal/min, and up to 350 ft. A non-metallic containment shell encloses and statically seals the entire impeller-rotor assembly along with the pump fluid. Inside are two shafts; the driven shaft and the driving shaft.

The driving shaft is located in the liquid end of the pump supported by sleeve bearings with the impeller and inner magnets mounted within. The driving shaft can either be a close-coupled motor shaft or supported by anti-friction bearings with the driving magnet inside. 
  • Impeller-Rotates and moves liquid out the discharge connection of the Casing
  • Fluid Containment Shell-Retains the pressure and is the barrier between the Inner Magnet Ring (IMR) and the Outer Magnet Ring (OMR)
  • Outer Magnet Ring (OMR)- Driven by the motor and causes the Inner Magnet Ring (IMR) to rotate
  • Bearing Assembly- Supports & maintains alignment of drive shaft and OMR
  • Coupling Housing- Supports & maintains alignment of Bearing Assembly with Casing
  • Inner Magnet Ring (IMR)- Rotates the Pump Shaft & Impeller (due to the magnetic attraction between the IMR and OMR)
  • Bush Holder- Supports internal bearings & provides a liquid path to lubricate the bearings
  • Shaft- Supports the Inner Magnet Ring and rotates Impeller
Commonly used to pump acidic and caustic solutions that generally cause seals to fail, these pumps are also ideal for toxic solutions that require complete containment. Some of the major areas where sealless pumps excel include Hot Oils, Gasoline, Ethanol, Hydrocarbons, Sour Water, Isobutane, Caustics, Amines, Disulfide oil, Acids (H2SO4), Anhydrous HF and HF acid.


The sealless magnetic drive design affords a wide range of operational benefits, making them a worthwhile alternative to traditional sealed pumps. Sealless magnetic drive pumps present absolutely no risk of emissions or leaks, which can harm productivity, employees and the environment.
