Inline Centrifugal Circulators

An inline centrifugal circulator is another type of pump commonly used in hydronic heating systems of small- to medium-size residential and light-commercial structures. The Bell & Gossett Series 90 inline centrifugal pump shown in Figures 10-15 and 10-16 is an example of this type of pump. It is a close-coupled, low-maintenance unit that can be mounted inline both vertically and horizontally. Because the motor can be disconnected from the pump body for servicing, there is no need to remove the pump body from the piping circuit for servicing.
