Think Sealless System – Why are magnetic drive pumps different?

A sealless pump is similar to a conventional centrifugal pump, but without packed glands or mechanical seals. The dynamic seal that would normally be used to seal the impeller shaft is instead replaced by a static containment shell, or shroud, to form a completely sealed liquid end or pressure boundary.

 

Prime mover energy is transmitted to the sealed liquid end and the impeller by a bank of external magnets, which pass force through the containment shell to the impeller shaft.

Mechanical seals are designed to leak, maintaining their sealing capability by leaking small amounts of fluid as a means of keeping the seal faces lubricated. This leakage then reaches the environment as either liquid or vapour via a process referred to as fugitive emission.

Why would you buy a pump that leaks?!  Mechanical seals are widely regarded as the weakest point in any pumping system accounting for a high proportion of all pump failures, the remainder being leakage through static seals such as gaskets / O rings and bearing failure.  It follows that if you eliminate the problem, you eliminate the failures and save costs.

Furthermore, seals, like bearings, must wear. As they wear, the seal faces lose their effectiveness and liquid loss through the seal increases. These fugitive emissions can be costly, resulting in lost time and money, as well as decreased worksite safety.

Sealless pumps don’t leak, meaning that they can help reduce process inefficiencies, maximise output and minimise the risks posed to your process environment and people including from hazardous and volatile materials.

Without seals, which will ultimately fail, requiring expensive maintenance, sealless magnetic drive pumps represent a cost-effective and highly reliable alternative to traditional sealed pump designs.

Think Sealless NOW – There has never been a better time

NOW is the time to specify and to install sealless magnetic drive pumps.

How long is it since you evaluated the considerable cost savings and safety benefits of sealless pumps against the traditional type of pump, which depend upon seals, with their inherent risk of leaks, to maintain integrity and contain your product? If it is some while, you may be surprised at how often sealless is now the solution, and how making a step change in your process technology could now benefit your business.

HMD Kontro has always been at the forefront of innovation, which is aimed at delivering what the industry needs.  We offer a design and an upgrade service backed up by our commitment to get products to the market faster than ever.

 

 

Moving with technological advances in new materials and composites

We pride ourselves on moving with latest technology advancements.  Recent innovations have included using new materials including composites to increase the efficiency of sealless pumps and increase their overall robustness. One example is the use of PEEK composite materials in our ZeroLoss® containment shell, which also reduces equipment life cycle costs. Our award winning VapourView® gas in liquid detector is at the forefront of innovation and offers complete sealless pump security.
