2. Booster pump - Wikipedia

   en.wikipedia.org/wiki/Booster_pump

   They will cycle whenever enough water is used to cause a pressure drop below the low set point. An accumulator in the upstream pipeline will reduce cycling. Variable speed pumps use pressure feedback to electronically control motor speed to maintain a reasonably constant discharge pressure.

3. Pumping station - Wikipedia

   en.wikipedia.org/wiki/Pumping_station

   In-line booster pumping into an elevated tank; High service pumping of finished water at high pressure; Distributed system booster without a storage tank in the piping system; Water pumping stations are constructed in areas in which the demand or projected demand is reasonably defined, and is dependent on a combination of customer needs and ...

4. Dry running protection - Wikipedia

   en.wikipedia.org/wiki/Dry_running_protection

   It is thus always recommended to install dry-running protection on all booster sets. There are three different methods for detection of water shortage: Pressure switch on suction manifold or float switch/electrode relay in the supply tank: Dry-running protection with pressure/level switch.

5. Pressure tank - Wikipedia

   en.wikipedia.org/wiki/Pressure_tank

   The diaphragm or bladder may itself exert a pressure on the water, but it is usually small and will be neglected in the following discussion. Case 1 is an empty tank at the charging pressure P c (gauge). The total volume of the tank is V t. Case 2 is a tank in use, with the air pressure at pressure P (gauge) and a water volume of V. Referring ...

6. Expansion tank - Wikipedia

   en.wikipedia.org/wiki/Expansion_tank

   An expansion tank or expansion vessel is a small tank used to protect closed water heating systems and domestic hot water systems from excessive pressure. The tank is partially filled with air, whose compressibility cushions shock caused by water hammer [ citation needed ] and absorbs excess water pressure caused by thermal expansion .

7. Fire pump - Wikipedia

   en.wikipedia.org/wiki/Fire_pump

   Fire pumps are used to increase the pressure of water sourced from a municipal underground water supply piping network, or a static supply (e.g., tank, reservoir, lake). A fire pump is a centrifugal- or positive displacement- pump that has been tested and listed by a third-party testing and listing agency, such as UL or FM Global specifically ...
