Viscous material pump, especially for a mobile viscous material pump

摘要

Thick-matter pumping device, in particular for a mobile slurry pump, with an at least pivotable S-tube (10a-n) having an input (11a) and an axially parallel to the input (11a) offset output (12a), with one to the S-tube (10a-n) adjoining output pipe section (17a-n) adapted to be connected to the outlet (12a) of the S-pipe (10a-n) and having at least one seal (18a; 18b; 18c; 18g ), which has at least two mutually rotatable sealing surfaces (15a-n, 16a-n), which are provided to seal a connection between the S-tube (10a-n) and the output tube piece (17a-n), wherein the seal ( 18a, 18b, 18c, 18g) has at least one wear element (13a, 14a, 13b, 14c, 14d, 13e, 14e, 13f, 14f, 13g, 14g, 14i) which has one of the sealing surfaces (15a, 16a, 15b, 16c ; 16d; 15e, 16e; 15f, 16f; 15g, 16g; 16i).
