When To Use a Magnetic Drive Pump
A wide variety of pumping mechanisms keep fluids circulating. For particularly tough fluids or dangerous situations, one model stands out above the rest—even when it’s submerged. A magnetic drive pump is a specific model of centrifugal pump that uses magnets to connect the pump to its motor instead of the mechanical shaft that most pumps use. Magnetic drive pumps feature hermetically sealed casings that protect components from fluids and shield people from electrocution when those pumps run underwater. Because there is no direct connection between the impeller and the drive magnet, pumps don’t require seals, which leads to significantly lower repair and maintenance costs. In this guide on when to use a magnetic drive pump, we’ll take a look at some applications for this important equipment—one of which could prove pertinent to spa operations.

Water Fountains

Water features can add a lot to the ambiance of a spa’s lobby. Fountains and moving water give guests a spot for quiet contemplation and add some calming tones to the room. To avoid the risk of electrocution, the hermetically sealed components of a magnetic drive pump are the best choice. You’ll find these pumps in water features of all sorts, whether as indoor attractions or as accents for yards and gardens.

Pumping Corrosive Fluids

Acids, strong bases, and other dangerous fluids shouldn’t come in contact with the components of a pump, lest they do damage. When working with these materials, a magnetic drive pump’s well-sequestered components and non-mechanical operation is the best choice. In addition to operating safely, fluids won’t leak as a result of the pump’s construction.

Fluids Without Suspended Solids

Though magnetic drive pumps can handle corrosive fluids, abrasive fluids can sometimes prove problematic. Slurries that contain iron particles aren’t ideal for a magnetic drive pump because of the naturally magnetic properties of iron and the likelihood of clogging the drive. Solids can grind against the pump’s components, wearing down important parts and potentially causing failure. This is a big issue considering magnetic drive pumps are designed to avoid the small repairs sealed pumps often require. The lower the viscosity of your fluid, the better a magnetic drive pump is for the job.
