A common application of the multistage centrifugal pump is the RO Water Plant, Pressure Boosting System, boiler feed water pump. All energy transferred to the fluid is derived from the mechanical energy driving the impeller. This can be measured at isentropic compression, resulting in a slight temperature increase (in addition to the pressure

Inline multi stage pumps. In-line multi-stage pumps are used in installations in which a high head is needed. Several impeller stages are connected in series and the inlet and outlet are on the same level. In-line multi-stage pumps are used for water supply, water treatment and almost any industrial solution including those for aggressive liquids.

18/7/2017 · On the discharge side, the pressure generated from the pump must be enough to overcome the high pressure inside the boiler. All centrifugal pump curves show a decrease in pressure as flow increases. With single stage pumps, this means that a larger pump is needed to increase the pressure produced at a given flow rate.

1.4 Boiler Feed Pumps. The outlet of the deaerator is connected to the BFP suction and from there the working fluid is called "feed water (FW)" and reaches the boiler proper with the help of boiler feed pumps. It impels the FW with requisite pressure dictating the operating point of steam generation.
