Pumps: mechanical seal or magnetic drive? Available to Purchase

Reviews recent advances in shaft sealing technology, aimed at reducing maintenance cost by improving reliability. Looks in detail at the evolution of the conical seal housing and the magnetic drive. Reports on a research programme initiated three years ago involving user representatives, mechanical seal manufacturers, pump manufacturers and the British Hydrodynamics Research Group. As a result, five different seal designs were tested. Concludes that magnetic drive pumps are very reliable and that ultimately the use of a mechanical seal or a magnetic drive rests with the user in discussion with the pump manufacturer.
