What is a Magnetic-Drive Pump?
A magnetic-drive pump uses a magnetic coupling to transfer power from the motor to the impeller, eliminating the need for a traditional mechanical seal.
This enables:
- Hermetic, leak-free operation
- Lower maintenance
- Greater operational safety even with hazardous media
The system features two permanent magnets (one on the motor shaft and one on the internal impeller), separated by a containment shell that keeps the pumped liquid isolated, preventing emissions or contamination to the outside.
For certain high-criticality industrial uses, you can also consider alternatives such as pumps for aggressive chemicals and solvents or fully customized OEM solutions.
How do magnetic-drive pumps work?
The operating principle is straightforward. The rotor consists of a shaft and a pair of permanent magnets that generate a magnetic field. The internal rotor is housed within a casing made of a material compatible with the pumped liquid—the pump head. The internal shaft is connected to a magnet, placed at the back of the head in what is called the “can” (containment cup), completely isolated from the outside. There is a single static seal (typically an O-ring) for which only chemical compatibility must be checked.
The internal magnet can then be driven in two ways:
For smaller pumps, a “canned” brushless DC motor configuration is possible, in which the pump can is placed inside the stator windings. The windings generate a rotating magnetic field that couples directly to the internal magnet, transmitting motion. Beyond all the benefits of magnetic drive, this greatly reduces the overall size of the pump + motor assembly—key for compact designs.
Alternatively, the internal magnet is driven by an external magnet mounted directly on the motor shaft. The magnetic field between the two magnets transfers motion from outside to inside the pump.
