Abstract
A circulator pump-motor unit which has an impeller assembly that can selectively tilt between two positions is disclosed. Each of the two positions corresponds to aligning a suction port with one of two inlet ports. The unit can be used to, for example, change the path of hot water conveyed between these ports so that either a hot water system or a hydronic system gets heat.
