Pump applications increasingly demandhigher operating pressures, temperaturesand outputs whilst still offering maximumpossiblepumpefficiency.

KlausUnionhasmet thechallengeandhasdeveloped magnet drives with non-metallicisolationshells forhighpressuresup toPN40andanoutputofupto150kWat29001/min.

Wemustalsokeepinmindthesafetyofthesystem. Consequently, Klaus Union offersvarious solutions in terms of a secondarybarrierfordifferentapplications.

Enhancing Energy Efficiency by the Use of Non-metallic Isolation Shells

– even for high system pressures applica-tions or applications requiring high pump output

Thankstotheleak-freemagnetdriveconcept,centrifugal pumps with magnet drives havewonan increasingmarketshare in theche-micalandpetrochemicalindustries.Throughthe use of non-metallic isolation shellsinstead of the traditionally used metallicisolationshells, theeddycurrent lossesareeliminated and the efficiency of the magnetdrivepumpsisthussignificantlyincreased.

Formanyyears,KlausUnionhasusednon-metallicisolationshellsandparticularlytho-semade fromceramicsandplastics for va-rious applications. Up to now, however, theoperative rangehasbeen limiteddue to thespecificcharacteristicsofthematerialsused.

Secondary sealing

Tosafeguardagainstimmediateproductlossin the event of an isolation shell leakage,thepumpscanbesuppliedwithasecondarysealing.Thesecondarysealingconsistsofahigh-performanceradialshaftsealringmadefrom PTFE. Research has shown that theradialshaftsealringcanwithstandpressuresofupto30bar.

The secondary sealing is available in two different construction types:

Construction type “L“ The radial shaft seal ring is installed in thebearing support between the anti-frictionbearings. This results in a particularlyspace-saving design, so that the pump withsecondarysealing„L“canalsobesuppliedinthestandardconstructionlengthasSLMNVNtoDINENISO22858.

Construction type “W“ The radial shaft seal ring is integrated intothe thermal barrier “W“ and seals betweentheoutermagnetcarrierandtheanti-frictionbearings.
