Brushed DC Motors for Magnetic Gear Pumps

Reliable and Economical Solution for Fluid Transfer and Dosing Systems

Brushed DC motors are widely used in compact magnetic gear pumps due to their simple design, stable operation, and affordable cost. For many industrial and laboratory tasks, these motors remain an effective and practical drive solution.

In fluid transfer systems, brushed motors are particularly suitable for equipment where compact size, basic speed control, and stable operation at low loads are important.

What is a Brushed DC Motor

A brushed DC motor is an electric motor that operates on direct current voltage. Current is transferred via brushes and a commutator, ensuring stable rotation and simple speed control.

Thanks to its design, this type of motor features:

  • easy integration;
  • low cost;
  • compact size;
  • convenient control.

This is why brushed DC motors are often used in small magnetic pumps, dosing systems, and laboratory equipment.

Key Advantages of Brushed DC Motors

Compact Design

Brushed motors have a relatively small footprint and are well-suited for compact pumping systems where space saving is crucial.

Simple Speed Control

The motor's rotational speed can be easily adjusted by varying the voltage, allowing for control over fluid flow in the pumping system.

Low Cost

Compared to servo drives or brushless systems, brushed DC motors are a more economical solution for standard fluid transfer tasks.

Good Starting Characteristics

These motors provide stable startup and are suitable for equipment with frequent on/off cycles.

Easy Maintenance

The motor's design is well-known and widely used in industry, simplifying maintenance and component replacement.

Why Brushed DC Motors Are Suitable for Magnetic Gear Pumps

Magnetic gear pumps require a stable and consistent drive for precise fluid delivery. Brushed DC motors handle this task well in systems with moderate accuracy and reasonable loads.

This solution is particularly effective for:

  • compact dosing systems;
  • laboratory equipment;
  • fluid circulation systems;
  • small industrial installations;
  • continuous feed equipment.

Additionally, the compact size of the motor allows for the creation of small pump modules for integration into automated systems.

Suitable Applications

Laboratory Equipment

Brushed motors are widely used in laboratory pumps for delivering reagents and low-flow liquids.

Medical Systems

Their compactness and stable operation make them suitable for medical dosing devices and analytical equipment.

Ink Delivery Systems

In inkjet printing and industrial marking equipment, stable fluid delivery is required within compact system dimensions.

Chemical Dosing

For standard chemical processes, brushed DC motors ensure reliable pump operation under moderate load.

Cooling and Circulation Systems

Motors are suitable for small circulation pumps and cooling circuits in industrial equipment.

When to Choose a Brushed DC Motor

A brushed motor is a good choice if:

  • an economical solution is required;
  • the system has compact dimensions;
  • ultra-high precision is not needed;
  • simple speed adjustment is necessary;
  • the equipment operates in standard industrial conditions.

When to Choose Another Type of Motor

In some cases, other types of drives are recommended:

  • For high-precision dosing, stepper or servo motors are more suitable.
  • For continuous 24/7 operation, brushless DC motors are preferred.
  • For hazardous areas, explosion-proof motors must be used.

Recommended Pump Series

Brushed DC motors can be used with various series of magnetic gear pumps for compact and standard fluid transfer tasks.

Suitable solutions:

  • micromagnetic gear pumps;
  • pumps for laboratory dosing;
  • compact chemical pumps;
  • systems for low-viscosity fluid delivery.

Conclusion

Brushed DC motors remain a sought-after solution for magnetic gear pumps due to their simplicity, affordability, and reliability.

For systems where compactness, stable fluid delivery, and cost-effectiveness are important, this type of motor provides efficient and practical operation across a wide range of industrial applications.
