Pump type series SLM AVP according to API 685

This pump for refineries and the petro-chemical industry is the consistent furtherdevelopment of the proven Klaus Unioncentrifugal pumps with magnet drive andwithoutshaftseal.

TheKlausUnionpumptypeseriesSLMAVPfulfils the high technical and economicdemandsthatrefineriesandthepetrochemi-cal industry impose todayonpumpswithoutshaftseals.

Fromasafety-engineeringpointof view, theSLM AVP is an enhancement of the pumpswithmechanicalsealformerlyutilised,whicharedescribedintheAPI610standard.

Theconstruction typewithoutshaft sealbutwithmagnetdriveguaranteesthatthepumpis absolutely leak free, in accordance withthe TA-Luft specification (German TechnicalInstructiononAirQualityControl),andmain-tenance-free in operation, compared to theversionwithmechanicalseal.

Magnet drive (API-§ 9.1.3/6.1.6)

The magnet drive is configured concentri-cally and transmits torque without slip viathe field of the permanent magnets. Thethermally stable samarium-cobalt material(Sm2Co17) withstands operating tempera-turesofupto400°C.Themagneticmaterialaluminium-nickel-cobalt (AlNiCo) is utilisedforhighertemperaturesofupto450°C.

Asecondpressurisedflushflow is takenoffat a high pressure location in the hydraulicsystemandfedtothemagnetdrive,whereitprovides for the necessary heat dissipation.The pressurised flush flow ensures that thetemperature rise in the isolation shell areadoes not lead to evaporation of the pumpedliquid(seeFig.2).

Klaus Union-Standard: Single isolation shell with leakage monitoring and drain at the in-termediate lantern. (API-§ 3.66)

The standard version of the SLM AVP pumpisequippedwithasingle isolationshell.Theintermediate lantern is equipped with alabyrinth system to the atmosphere,a leakage monitoring system and a drainconnection. A pressure gauge or a liquidsensor can be utilised as a leakagemonitor. The labyrinth seal upstream of theanti-friction bearings serves as a throttlingpoint in the event of isolation shell damageleading to product escaping into the inter-mediate lantern. The pressure rise or thepresence of liquid is detected by the moni-toringsystem.ThisdesigncorrespondstothesecondarycontrolsystemdescribedinAPI685(§3.66).

Optional: Double isolation shell with pressure monitoring. (API-§ 3.64)

In this version, the pressure-containingsecond (outer) isolation shell serves assecondary containment and thus fulfils theAPI definition of the secondary containmentsystemaccordingto§3.64.Theouterisolationshellisarrangedconcen-tricallyaround the inner isolationshell.Thepressureismonitoredinthecavitybetweenthetwocontainmentshellsandisconfiguredwithapressurebelowatmosphereinthestateofthepumpasdelivered. It is thuspossible todetect isolation shell damage from outsideandfrominside.Intheeventofdamagefromoutside, the pressure monitor will indicateatmosphericpressure;whereasintheeventofdamagefrominside,thesystempressurewillbeindicated.

Outer magnet carrier protection (API-§ 9.1.3.5) and rubring zones (API-§ 9.1.3.3)

To protect the isolation shell, rubring zonesareprovidedonboththeoutermagnetcarrierandtheinnermagnetcarrier.Intheeventofadeflectionofthemagnetrotors,thiseffectivelyavoidscontactoftherotorswiththeisolationshelltoavoiddamagingtheshell.
