Abstract
An impeller clearance adjustment system provides for the desired clearance between an impeller and suction housing irrespective of the amount of torque applied to the bolts of the adjustment system. A bearing housing has a plurality of generally evenly spaced apart threaded first openings while a bearing frame has a plurality of threaded second openings registerable with the first openings. A twinsert is threadably received within each of the plurality of second openings. An adjustment bolt, having an opening in its central axis, is threadably inserted into each of the first openings and abuts a face of a twinsert. An attachment bolt is inserted through each adjustment bolt's opening and is threadably received within the respective twinsert. Once the impeller clearance is set, each attachment bolt is tightened thereby maintaining the set impeller clearance.
