Industrial pumps

Engineered for maximum reliability in critical process applications

In industries where hazardous, corrosive, or high-value fluids are handled, pump reliability is non-negotiable. Unplanned downtime, product leakage, and seal failures can have significant operational, environmental, and financial consequences.

Magnetic drive technology has become the preferred solution for sealless centrifugal pumps operating in demanding process environments. By eliminating the need for mechanical shaft seals, magnetic couplings provide completely hermetic torque transmission while significantly improving operational reliability and reducing maintenance requirements.

Bakker Magnetics partners with leading OEM pump manufacturers to develop high-performance magnetic coupling systems optimized for efficiency, torque density, thermal stability, and long service life.

Combining advanced magnetic engineering, simulation-driven design, and more than 50 years of experience in permanent magnet technology, we support customers throughout the complete product development cycle, from concept engineering to serial production.

Engineering magnetic couplings for critical pump applications

Every pump application presents its own engineering challenges.

Operating temperature, pressure, rotational speed, transmitted torque, containment shell material, chemical compatibility, and installation space all directly influence magnetic coupling performance.

Rather than offering standard magnetic components, Bakker Magnetics develops application-specific coupling solutions designed around the customer’s performance requirements. Our engineering teams work closely with OEM designers to optimise:

  • Maximum transmitted torque
  • Coupling efficiency
  • Rotor stability
  • Thermal behaviour
  • Eddy current reduction
  • Magnetic field distribution
  • Compact design
  • Long-term operational reliability

The result is a magnetic coupling fully integrated into the overall pump design rather than functioning as a stand-alone component.

The advantages of magnetic drive technology

Compared with conventional mechanically sealed pumps, magnetic couplings offer substantial operational benefits.

Hermetically sealed operation
Torque is transferred contactlessly through a containment shell, eliminating dynamic shaft seals and preventing process fluid leakage. This makes magnetic drive pumps particularly suitable for:

  • Hazardous media
  • Corrosive chemicals
  • Flammable liquids
  • Explosive environments
  • Ultra-pure process fluids
  • High-value chemicals

Increased operational reliability
Mechanical seals are among the most common causes of pump failure.
Removing the mechanical seal significantly reduces wear, maintenance requirements, and unplanned downtime while increasing equipment availability.

Lower lifecycle costs
Although magnetic drive systems may require a higher initial investment, they frequently deliver the lowest Total Cost of Ownership through:

  • Reduced maintenance incidence
  • Planned downtime
  • Longer operating life
  • Increased process uptime
  • Improved energy efficiency
  • Lower environmental risk

Simulation-driven engineering

Successful magnetic coupling design begins long before manufacturing.
Bakker Magnetics applies advanced Finite Element Analysis (FEA) throughout the engineering process to predict system behaviour under real operating conditions.
Simulation enables optimisation of:

  • Magnetic flux distribution
  • Torque transmission
  • Rotor dynamics
  • Demagnetisation margins
  • Thermal loading
  • Eddy current losses
  • Structural integration

Numerical optimisation allows multiple design iterations before prototype manufacturing, reducing development time while improving final product performance.

Magnetic material selection

Selecting the correct permanent magnet material is fundamental to long-term coupling performance.

Neodymium Iron Boron (NdFeB)
NdFeB provides the highest available magnetic energy density, enabling compact couplings capable of transmitting high torque within limited installation space.
Typical applications include:

  • Chemical process pumps
  • API pumps
  • Industrial centrifugal pumps
  • High-efficiency pump systems

Samarium Cobalt (SmCo)
For elevated temperatures or aggressive chemical environments, SmCo often provides the optimal solution.
Advantages include:

  • Superior thermal stability
  • Excellent corrosion resistance
  • Outstanding magnetic stability
  • Long service life under severe operating conditions

Material selection is always based on application requirements rather than catalogue specifications.

  • Permanent magnet technology
  • Magnetic circuit design
  • Finite Element Analysis
  • Application engineering
  • Prototype development
  • Testing and validation
  • Manufacturing engineering
  • Quality assurance
  • Global supply chain management

Rather than supplying individual magnetic components, we engineer complete magnetic coupling systems that integrate seamlessly into your pump architecture.
