Basics of Magnetic Drive Pump Technology

Magnetic drive pumps are a Centrifugal Pump in which the motor is coupled to the pump by magnetic technology rather than by a mechanical shaft. The pump consists of three main parts: the driving magnet, the driven magnet, and the magnet cup.

The driving magnet is connected to the motor and is radially aligned with the driven magnet, the latter of which is connected to the pump. The magnets are separated by the magnet cup, which acts as a static barrier between the two and seals the pumped fluid from the atmosphere, resulting in a ‘seal-less’ design. This barrier is also referred to as a hermetic seal. The driving magnet rotates as power is applied to the motor and the driven magnet follows suit, compelled by magnetic attraction.

Magnetic Drive Pumps

This pump type has been available for several years. Mag drive pumps have recently become more popular due to recent advancements in magnet technology combined with more stringent application requirements, the incompetence of mechanical seals, and new legislation regarding fugitive emissions.

Magnetic Drive Pumps provide several benefits:

Seal-less design: No mechanical seal is required

Zero leakage / 100% emissions free

High reliability/ lower maintenance

Safer operations pumping hazardous fluids

These advantages are the primary reason why more pump users are turning to mag drive pumps. Their increased reliability and lower total cost of ownership have also contributed to an increased demand for the pumps over more conventional options. Highly reliable and safe to operate, magnetic drive pumps are the best choice for handling hazardous and expensive fluids in a variety of applications.
