Abstract

Fluidpumpe, drevet av en integrert, innkapslet motor og omfattende et pumpehus (4) med en gjennomgående, sylindrisk kanal (6). En forseglet, ringformet stator (10) omslutter pumpehuset. En skovlhjulenhet (16) er dreibart opplagret i pumpehuskanalen. I skovlhjulenheten inngår et aksialstrøms-skovlhjul (18) og en forseglet rotor (20) som er montert rundt skovlhjulperiferien. Lagre, med innbe- fatning av aksialtrykklagre (24) er montert mellom skovl- hjulenhets-periferien og pumpehuset. Et radialstrøms- hjelpeskovlhjul (28) kan være forbundet med skovlhjul- enheten, for frembringelse av en radialstrøm av vann fra den sylindriske kanal i pumpehuset til en perifer fluid- sirkulasjonskanal (26) mellom skovlhjulenheten og pumpe- huset. Hjelpeskovlhjulet bringer den perifere fluid- sirkulasjonskanal under trykk.
