Centrifugal Pumps An Insider’s Tip for Pumps: Why You Should Consider Borosilicate
Permanently magnetically coupled centrifugal pumps with borosilicate canister—The most central topic in the development of magnetically coupled pumps is the improvement of energy efficiency. Newly developed magnetically coupled centrifugal pumps with a borosilicate canister are an energy-efficient alternative to all conventional pumps with mechanical seals.
Increasing demands in manufacturing processes require economical solutions that are easy to operate. Today, many companies are still using pumps with mechanical seals. The variety of such pumps is in fact relatively large, although the disadvantages of such a pump construction become obvious relatively quickly.
Leakage and production halts as well as corrosion and pitting is often the consequence. Such incidents inevitably lead to higher production costs, hence increasing the often low purchase price of the pump by many times.
As this article shows, there is an alternative to mechanical seals which not only enables long-term cost savings through increased energy efficiency, but also contributes to environmental protection and additionally is absolutely safe in application. The alternative is a magnetically coupled pump which is sealed via a canister instead of a mechanical seal. These pumps are not only wear and leakage free, but also especially energy efficient. For example, this principle of sealing is applied by a newly developed canister made from borosilicate (hardglass).
Problems of Pumps with Mechanical Seals
Almost every production process makes use of media that are highly toxic or aggressive. Pump units must convey or circulate these substances which often put them under great strain. Currently, centrifugal pumps with mechanical seals are still being used, which are often unable to cope with the strain for a long time. Through the conveying of the media, friction on the seals is generated which unavoidable causes leakage and possibly corrosion.
This often results in problems on the machine and, as a consequence, might lead to production halts and leaking of dangerous substances which may cause hazard to humans. This results in higher production and environmental protection costs, hence increasing the often low purchase price of the pump by many times. Furthermore, the financial consequences with regard to expensive repairs and long-term expenses for maintenance are significant.
