(72) TUOMISALO, Aki (FI) (73) METSO OUTOTEC SWEDEN AB, Box 132, 231 22 TRELLEBORG (SE) (74) Cabinet Spoor & Fisher Inc. Ngwafor & Partners, The House of Gideon, Golf/Bastos Quater, Opposite The American Embassy, Entrance-Saint John Paul II Boulevard, P.O. Box 8211, YAOUNDE (CM). (57) The disclosure relates to a wear element (23) for a slurry pump arrangeable in a pump housing, wherein at least a portion of the wear element (23) produces a magnetic field for attracting magnetic particles in a slurry processed by the slurry pump. The wear element comprises a magnet for producing the magnetic field, arranged such to generate formation of a protective wear layer on a surface of the wear element when used in a slurry pump. The disclosure further relates to a slurry pump (1) comprising a pump housing (2) and a wear element (23) arranged within the pump housing (2), wherein at least a portion of the wear element (23) produces a magnetic field for attracting magnetic particles present in a slurry processed by the slurry pump (1). The disclosure also relates to a method for producing a protective wear layer in a slurry pump comprising the steps of arranging a wear element in a housing of the slurry pump, wherein at least a portion of the wear element produces a magnetic field; and pumping a slurry comprising magnetic particles through the slurry pump, whereby magnetic particles of the slurry are attracted by the magnetic field, thereby creating the protective wear layer on the wear element. ________________________________________ (11) 21804 Consulter le mémoire (51) F04D 29/42 (2018.01); F04D 7/04 (2018.01) (21) 1202300352 - PCT/EP2022/055813 (22) 08/03/2022 (30) EP n° 21161588.5 du 09/03/2021 (54) Slurry pump.
