    en.wikipedia.org/wiki/Boiler_feedwater_pump

    Large industrial condensate pumps may also serve as the feedwater pump. In either case, to force the water into the boiler, the pump must generate sufficient pressure to overcome the steam pressure developed by the boiler. This is usually accomplished through the use of a centrifugal pump.

    Boiler water is treated to prevent scaling, corrosion, foaming, and priming. Chemicals are put into boiler water through the chemical feed tank to keep the water within chemical range. These chemicals are mostly oxygen scavengers and phosphates. The boiler water also has frequent blowdowns in order to keep the chloride content down.

    en.wikipedia.org/wiki/Chiller_boiler_system

    A chiller boiler system is a hydronic system. It uses water instead of air to heat and cool a structure. A properly designed hydronic system is usually more efficient than a standard forced air system. [1] Chiller boiler systems use radiant heating and cooling or fan coil systems to condition a home or business. This allows for multiple zones ...

  7. Peristaltic pump - Wikipedia

    en.wikipedia.org/wiki/Peristaltic_pump

    A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing. Most peristaltic pumps work through rotary motion, though linear peristaltic pumps have also been made.
