ABSTRACT:
A high pressure centrifugal slurry pump in which the impellers and their associated diffusers are formed of hard chrome iron. A liquid-tight high pressure containment shell surrounds the impellers and diffusers and is radially spaced from them. The resulting space between the array of impellers and diffusers and the containment shell is in fluid communication with the interiors of the impellers and diffusers, preferably through a channel located between the last diffuser of the pump and the end wall at the high pressure end of the pumping chamber.
