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 frame has a plurality of generally evenly spaced apart threaded first openings while a bearing housing has a plurality of threaded second openings registerable with the first openings. An adjustment bolt, having an opening in its central axis, is threadably inserted into each of the second openings and abuts the bearing frame. An attachment bolt is inserted through each adjustment bolt's opening and is received within the respective first opening. Once the impeller clearance is set, each attachment bolt is tightened thereby maintaining the set impeller clearance.
