Abstract (en)
[origin: EP2469093A1] The pump (10) has a shaft (28) movable in rotation around a longitudinal axis in a cavity (22) of a cartridge (20) of a motor (16), where the shaft is made of stainless steel or ceramic. Conduits allow the circulation of fluid in the shaft. The conduits are in communication with the cavity and extended along the shaft in a rectilinear or helical manner. A fluid circulation wheel is driven in rotation by the shaft. One of the conduits is formed between outer and inner tubes of the shaft. A magnet rotor (26) is encapsulated with stainless steel and fixed to the shaft.
