Why use Magnetic Drive Pumps?

Magnetically driven pumps have proved invaluable in many applications from chemical manufacturing to effluent disposal; brewing to renewable energy, and the trustworthiness of these mag drive pumps is a guarantee that their use will continue to grow. Though not an entirely new concept – magnetic drive pumps have been around for a number of years, Crest Assoma mag drive pumps are on a path of continuous improvement with constant R&D looking for new ways to increase efficiency and reliability, whilst reducing running costs and downtime.

Years ago, most pump shafts were sealed using rings of soft packing, compressed by a packing gland, but this type of shaft seal required a fair amount of leakage just to lubricate the packing and keep it cool. Then came the mechanical seal, which creates a seal with two very flat surfaces (one stationary and one rotating). But mechanical seal faces still require some leakage across the faces in order to form a hydrodynamic film. This normally evaporates and is not noticeable and in certain applications, for example where solids are involved, mechanically sealed pumps are still the best option. But for applications where the liquid is highly corrosive, toxic and/or expensive, where safety and cost efficiency are paramount, a magnetic drive pump is the best option because it is seal-less, meaning zero risk of leakage.

Using magnets to create a balanced magnetic field to create the rotation of the impeller, these seal-less mag drive pumps eliminate the need for a direct drive mechanism as the magnetic field replaces it. The two parts of the process are exactly that – two parts – and so as the shaft of the motor doesn’t enter the inside of the pump there is no need for a shaft seal and the risk of leakage is eliminated.

The seal-less pumps are a boon to the local environment; eliminate the need to clean up spills; and maintenance costs are much reduced due to the absence of a shaft seal to maintain. The full carbon/ceramic magnetic drive range is also engineered with run dry protection, allowing it to run for up to eight hours without damage.
