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
- Improved operational safety, even with hazardous fluids
The system features two permanent magnets (one on the motor shaft, one on the internal impeller) separated by a containment shell that preserves the integrity of the pumped fluid, preventing contamination or emissions to the outside.
For highly critical industrial applications, you can also consider alternatives such as pumps for aggressive chemicals and solvents, or custom OEM solutions.
How 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 compatible with the pumped liquid (the pump head). The internal shaft is connected to a magnet located at the rear of the head, inside the “containment cup,” fully isolated from the exterior. There is only one static seal (typically an O-ring), for which you must verify chemical compatibility.
The internal magnet can then be driven in two ways:
For smaller pumps, a “canned” brushless DC motor configuration is possible, where the pump’s containment cup is inserted within the motor windings. These windings generate a rotating magnetic field that couples directly to the internal magnet, transmitting motion. Alongside the benefits of magnetic drive, this arrangement significantly reduces the overall pump + motor size — crucial in some applications.
Alternatively, motion is transmitted by an external magnet mounted directly on the motor shaft. The magnetic field between the two magnets transfers torque from outside to inside the pump.
