Descrizione Description

Pompe centrifughe di processo a doppio supporto, sin-gola o doppia girante, progettate e costruite in accordoalla normativa API 610, 10a edizione. Le HPD sono pompe monostadio con girante a doppiaaspirazione e corpo a divisione radiale.Le HPE sono pompe a due stadi con la prima girante asingolo o doppio imbocco, secondo la portata di proget-to. Entrambe le linee di pompe corrispondono alla formacostruttiva BB2 prevista dalla normativa di riferimento. La costruzione compatta ed il generoso dimensiona-mento dei singoli componenti e dell'assieme le rendonoidonee ai servizi più gravosi: in queste pompe, le spinteassiali sono intrinsecamente bilanciate in modo daminimizzare il carico su albero e cuscinetti reggispinta.La cura nella progettazione, nella costruzione e nellabilanciatura dinamica delle parti rotanti garantisconoaffidabilità e livelli di vibrazioni particolarmente conte-nuti.Per i servizi a temperature elevate è previsto il raffred-damento dei cuscinetti mediante uno scambiatore dicalore realizzato in acciaio inossidabile e progettato inmodo da poter essere facilmente inserito e rimosso permanutenzione dal supporto cuscinetti, senza necessitàdi smontare il supporto stesso. In alternativa, e' previ-sto il raffreddamento ad aria su entrambi i lati dellapompa mediante ventole calettate sull'asse, anch'esseappositamente disegnate e realizzate in alluminio pres-sofuso. Le pompe HPE e HPD possono essere realiz-zate in tutte le combinazioni di materiali previste dallanormativa di riferimento ed in materiali speciali perservizi su liquidi aggressivi.

Single and two stage between bearing process pumpsdesigned and manufactured according to API 610, 10thed. HPD are single stage double suction radially splitcasing pumps.HPE are two stage pumps with either single or doublesuction first stage impeller, depending on the designcapacity.Both series of pumps correspond to type BB2 asdescribed in the reference standard.Compact design and generously sized componentsmake these pumps suitable for the most critical appli-cations: in the HPD and HPE pump series, the axialthrust is intrinsically balanced in order to minimize shaftand bearings loads.Care in design and manufacturing as well as dynamicbalancing of rotating parts will grant equipment reliabi-lity and smooth operation with low residual vibrations.For high temperature duties, cooling of the bearingscan be obtained by means of specifically designedstainless steel integral coolers which can easily beinstalled and removed for maintenance purposeswithout dismounting the bearing housing. As an alter-native, custom designed, integrally cast aluminium airfans can be fitted on both drive and non drive end .HPD and HPE pumps can be manufactured in all thematerials combination foreseen by the reference stan-dard and in special alloys for chemically aggressiveservices.
