ABSTRACT:
A primary recirculating pump for pressurized water or boiling water nuclear reactors has a spherical housing with a radially extending integral outlet, a rotary impeller which is insertable or removable through a sealable opening of the housing, and a composite inlet including an outer section which is integral with the housing and a discrete inner section which is insertable and removable through the opening and serves to convey to the impeller, and to preferably accelerate, the fluid which enters through the outer section. The inner section may resemble a bend or a funnel which diverges from the impeller toward the outer section, and the outer section may resemble a bend, a substantially straight pipe which extends tangentially of the housing, or a helical or semihelical conduit. The plane of the outer section is closely adjacent to or even coincides with the plane of the outlet, especially when the outer section is tangential to the housing or resembles a portion of or an entire helix.
