Steam Boiler Feed Pumps & High Pressure Boiler Feed Water
See Fig. 1 Boiler feed pump. Fig. 1 Boiler feed pump: Model with VP-EM-RG-HP layout. The low-speed booster pump is usually driven by the free shaft end of the turbine via a step-down gear or directly by the free end of the electric motor.

These pumps move a higher volume of condensate than standard steam condensate pumps. Use them in low-pressure steam systems to capture hot condensate and return it to your boiler or feed unit. Pumps turn on when the tank is 2/3 full and turn off when condensate drops to 6" deep.

The duty of the boiler feed pump as determined by the boiler and turbine pressure flow conditions, is given by Fig 1.71.Shown on the diagram are the boiler feed-pump characteristics, i.e., the relationships between the head produced by the boiler feed pump corresponding to the particular value of feed flow pumped, and the boiler feed pump speed.
Large industrial pumps may also serve as the feedwater pump for returning the condensate under pressure to a boiler. Condensate pumps usually run intermittently and have a tank in which condensate can accumulate. Eventually, the accumulating liquid raises a float switch energizing the pump.

As taking suction from a condensate system is a high pressure application, steam boiler feed pumps are generally high head, low flow pumps, making multistage pumps a common choice. Side channel pumps are also a popular solution for high pressure boiler feed water pumps thanks to their ability to pump liquids with gas content.
