Abstract

The invention relates to a pump construction type comprising ceramic elements, in which the impeller (8, 16, 23) and casing walls (4, 9, 17, 20) adjacent to the latter are designed as disc-shaped elements. An impeller (8, 16, 23) arranged between the casing walls here slides sealingly along the casing walls (4, 9, 17, 20). <IMAGE>
