MEC-ACOSTRUZIONE Corpo pompa: del tipo a voluta con boccapremente flangiata, posta in posizione radialerivolta normalmente verso I'alto. Girante: del tipo chiuso, equilibratadinamicamente, con camera di bilanciamentoed anelli di tenuta, facilmente sostituibile, perla compensazione della spinta assiale. Coperchio aspirazione: fissato sul corpomediante viti prigioniere e dadi, con bocca diaspirazione assiale, flangiata. Supporto: del tipo a sedia, ampiamentedimensionato; funge da base di appoggio e, nelcontempo, sostiene a sbalzo la parte idraulica. Albero: guidato e sostenuto da due cuscinettia sfere alloggiati nel supporto a sedia elubrificati con olio; essi sono largamentedimensionati a permettere I'accoppiamento siaa motore elettrico che endotermico a mezzo digiunto elastico. Tenuta: a baderna registrabile, facilmentericambiabile, alloggiata nella camera stopparicavata nel corpo pompa; un circuito internodi sbarramento contro eventuali ingressi diaria ne assicura la lubrificazione Senso di rotazione: orario visto dal latocomando.CONSTRUCTION Pump casing: volutetype with top directedradially positioned flanged delivery outlet; Impeller: closed type, dynamically balancedwith thrust balancing chamber. The impeller isfitted easy replaceable wear rings Suction cover: fastened to the casing by studsand nuts, with axial flanged suction inlet; Support: bearing stand, amply sized; serves asa base and support of the overhanged wet end; Shaft: guided and supported by two oil lubricatedball bearings housed in the bearing stand support.Bearings are amply sized for coupling to electricmotors and endothermic engines by means offlexible coupling. Seals: adjustable packing, easily replaceable,housed in the pump casing’s packing gland chamber; an internal circuit prevents air from enteringand ensures lubrication Direction of rotation: clockwise viewed fromdrive side.CONSTRUCTION Corps de pompe: du type a volute avec tubulurede refoulement à bride, placé en position radialeet orienté normalement vers le haut ; Roue: du type fermé, équilibrée dynamiquement avec chambre d’équilibrage et anneauxd’étanchéité facilement remplaçables pour lacompensation de la poussée axiale; Couvercle d’aspiration: fixé sur le corps depompe au moyen de goujons et d’écrous et comportant la tubulure d’aspiration axiale à bride; Palier: largement dimensionné et faisant fonctiond’appui pour la fixation de I’ensemble et sur lequella partie hydraulique est montée en porte-à faux; Arbre: guidé et soutenu par deux roulements àbilles logés dans le support et lubrifiés à I’huile.Ils sont largement dimensionnés pour permettreI’entraînement par moteur électrique ou thermiquepar I’intermédiaire d’un accouplement élastique. Garniture: à tresse facilement remplaçable logéedans une chambre du corps de pompe, un circuitinterne fait barrage contre les entrées éventuellesd’air et assure la lubrification de la tresse. Sens de rotation: horaire vu côté entraînement.materiali pompa - Pump materials - Matériaux pompe- Corpo mandataGhisa grigia- CoperCHio aspirazioneGhisa grigia- DELIVERY CASINGCast iron- SUCTION CASINGCast iron- CORPS DE REFOULEMENTFonte grise- COUVERCLE D'ASPIRATIONFonte grise- GiranteGhisa grigiaGhisa sferoidale per:(mod. 004/80)Bronzo per:(mod H5/100, zrBH2/125,zrBH3/125, zrBH4/125)- IMPELLERCast ironNodular cast iron:(mod. 004/80)Bronze:(mod.
