1. A pump front side part for use with a centrifugal slurry pump for pumping a fluid mixture containing particulate matter, the pump side part comprising a main body having a main axis (Y-Y), the main body including a side wall section which extends laterally with respect to the main axis and has opposite facing first and second sides, the main body further including an inlet section which extends from the first side in the direction of the main axis and is co-axial therewith, the inlet section having an outermost end and an innermost end defining a passage of the inlet section therebetween, an outer peripheral side wall or rim extending between the first and second sides, the second side having an outer edge adjacent the peripheral side wall or rim and an inner edge located at the innermost end of the passage of the inlet section, a plurality of formations on a surface of the second side including an inner formation and an outer formation in spaced relation to the inner formation, the formations being circular or ring like in configuration when viewed in the direction of the main axis (Y-Y) and arranged concentrically with the main axis (Y-Y), wherein the formations are in the form of channels or recesses in the surface of the second side, and the channels are continuous and arcuate in cross-sectional profile to effect a reduction of particle settling effect on the second side of the side wall section, wherein the second side includes an inner region inclined in a direction away from the first side of the side wall section as the inner region extends towards the inner edge, and wherein the inner formation is located on the inner region of the second side and encircles the inner edge and the inner formation is smaller in size than the outer formation.
