Abstract

This invention relates to an improvement in a pump for high operating pressures, particularly a main coolant pump for pressurized water or boiling water reactors comprising a pressure housing, a vertical pump shaft having an impeller thereon, a distributor surrounding the impeller, and suction and discharge connections, the pump shaft having an axis normal to the axis of the suction and the discharge connections. The improvement comprises a separator plate having an opening therein and dividing the pressure housing into a lower section constituting an inflow chamber and an upper section constituting a discharge chamber, the upper section containing the impeller and the distributor, and the inflow chamber and the discharge chamber constituting rotational chambers which are mechanically machined.
