All reusable parts are cleaned either by sand blasting, glass beading, pressure washing or hand cleaning. Parts are replaced as required, either manufactured by BO-GE Assembly or those from the customers stock. Rotating parts are balanced to well below API specifications and the unit is final assembled.
