Centrifugal pump recirculation line This long-awaited new edition is the complete reference for engineers and designers working on pump design and development or using centrifugal pumps. This return system design ensures that there is always hot water in the trunk or main line but it is essential that the hot water recirculation lines are as close to all fixtures as possible. This utilizes a booster pump that forces the hot water to the fixture that is farthest away.
You can select the pump based on the. Connect the pump and the Pump Manager. While the minimum safe continuous flow can be calculated the following guidelines are offered by pump manufacturers.
