Pumps with magnetic drives are made to transmit torque and power from a motor to a fluid. Despite their potential for success, they have a number of drawbacks.

First, when a magnetic drive's torque exceeds its capacity, it may decouple. The breakaway torque has the potential to stop the impeller from rotating. This is a bad circumstance. In fact, a pump may become permanently demagnetized if it is run at high speeds for an extended period of time.

Second, the liquid's temperature can affect magnetic drives. Frictional losses may be substantial if the liquid has a high viscosity.

Thirdly, the wear rate of the bearings may increase if the magnetic drive is used in an aggressive or corrosive medium. Other components of the pump may also sustain damage.

Pumps with magnetic drives, also known as "mag drive pumps," work by magnetic attraction. Compared to mechanical seal pumps, they contain fewer moving parts. These are typically used in difficult-to-seal applications, such as those for hazardous materials. This makes maintaining these pumps less expensive, as well as enabling them to operate more effectively and with less downtime.

They do have limitations, though. For instance, they are only capable of handling 5% solids. The chemical being pumped through the plastic lining has the ability to diffuse, which allows it to accumulate in the passages. The bearings, for example, are one of the parts of the pump that are subject to wear with Separator.

This occasionally can result in failures and downtime. Many facilities are switching to seal-less pumps as a result of these factors.
