A hot sludge pump comprises a bidirectional flow pipe (4) and an expansion joint (5) for compensating the heat-induced change in length of the bidirectional flow pipe (4), wherein the expansion joint (5) comprises a linear guide (6) and a sealing device (7, 7') arranged between a region (8) of the pump which can be or is movably linked to the bidirectional flow pipe (4) and a stationary region (9) of the pump. |
