Specification of

An In-line Vertical Pump is a type of centrifugal pump that has a vertically oriented shaft, with the suction and discharge connections in the casing in line with each other, rather than requiring a change of direction like end suction pumps. They are commonly used as circulator pumps in situations where water flowing through a piping system needs to be pressurized. Some are designed to be easy to fit into a residential or commercial piping system, and they are commonly used for chilled water and hot water circulation in commercial buildings.

The main advantage of this pump configuration is the floor space savings that this creates, as compared to a horizontal end suction pump. A secondary advantage is that the piping is simplified, since the piping does not have to change direction as it does with an end suction pump. In many commercial building applications, in-line circulators are simply suspended in the piping, just like a valve .
