ABSTRACT:
A pump has an outer casing, an inner casing and a rotor within the inner casing. The inner casing is of brittle material of substantially U-shaped cross-sectional configuration with the legs of the U extending into sealed axially sliding contact each with one of a pair of covers between which the rotor is disposed. A pump is provided to introduce a fluid under pressure between the inner and outer casings thereby to place the inner casing in compression to prestress the inner casing in opposition to fluid pressure peaks within the inner casing.
