BOPI 02 BR / 2025 REPERTOIRE NUMERIQUE 14 transverse to a first plane within which the anchor point lies. The arrangement includes a tightening member operable for providing a tension force to pull the elongate member through the aperture. The articulating-tension washer is to be retained at the aperture to transmit a force between the tightening member and the elongate member, and includes an arcuate surface for location away from the aperture, the arcuate surface extends in an arc symmetrically across the direction of elongation of the elongate member.

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 suction liner (8) for a cenlrifugal pump (1) for processing slurries, the centrifugal pump comprising an impeller (3) housed in a casing (2), the suction liner (8) comprising a cylindrical portion (10) arrangeable in the casing (2) of the centrifugal pump (1), and a flange portion (11) which protmdes outtvards in a radial direction from the cylindrical portion (10). The flange portion (11) is arrangeable such that, when mounted in a centrifugal pump (1), at least a portion of a front end surface (12) of tlie flange portion (11) of the suction liner (8) abuts against at Ieast a portion of a front end (14) of the intpeller suchto seal an axial gap between the suction liner (8) and the impcllcr (3). and at lcast the front end surface (12) of the flange portion (11) is niade of a low friction polymer. The disclosure further relates to a centrifugal pump (1) for processing slurries, the centrifugal pump comprising such a suction liner (8). The suction liner (8) and the centrifugal pump (1) allow preventing recirculation of pumping liquid in a centrifugal pump and, therebv, reducing wear.
