A booster pump is a machine that increases the pressure of a fluid.They can be used with liquids or gases,but construction details will vary depending on the fluid.A gas booster is similar to a gas compressor,but is generally a simpler mechanism,usually with only a single stage of compression,used to increase the pressure of a gas already above ambient pressure.A two-stage booster was also built.The supercharger can be used to increase gas pressure, deliver high-pressure gas,fill gas cylinders and scavenge.

Water pressure

In new construction and renovation projects,hydraulic booster pumps are used to provide sufficient water pressure to the upper floors of high-rise buildings.A water pressure booster pump may also be required after a backflow preventer (BFP) is installed,currently mandatory in many cities Protecting public water supplies from pollutants entering public water supplies in buildings.The use of BFP began after the passage of the Clean Water Act.These devices can cause a pressure loss of 12 PSI and can cause the upstairs flush valve to not work properly.After a pipe is used for a long time, scale builds up on the inner surface,which causes a pressure drop as the water flows.

Structure and function of hydraulic booster Booster pump

Home water pressure booster pumps are usually simple electric centrifugal pumps with check valves.They can be constant speed pumps that turn on when the pressure falls below a low pressure set point and turn off when the pressure reaches a high pressure set point, or variable speed pumps that are controlled to maintain a constant output pressure.Fixed speed pumps are turned on by a normally closed low pressure switch and will run until pressure rises to open the high pressure switch.They will cycle as long as enough water is used to bring the pressure down below the low set point.An accumulator in the upstream piping will reduce circulation.Variable speed pumps use pressure feedback to electronically control motor speed to maintain a reasonably constant discharge pressure.Most applications use AC mains current and use an inverter to control motor speed.Installations supplying water to tall buildings may require boosters on multiple levels to provide acceptable consistent pressure to all floors.In this case, separate boosters can be installed at different stages,each booster increasing the pressure provided by the next lower stage.It is also possible to boost the pressure once to the desired maximum pressure and then use a pressure reducer at each stage.This method can be used if the roof has a storage tank that feeds water to the supply system by gravity.

Gas pressure

  • Gas boosting can be used to fill gas cylinders to a higher pressure than the available gas supply,or to provide process gas at a pressure higher than the line pressure.Examples include:

  • Breathing gas mixtures for underwater diving,where gas is supplied from high pressure cylinders,such as scuba diving, scuba displacement,and surface-supplied mixed gas diving,where the component gases are mixed by adding partial pressures to      storage cylinders,and mixtures the storage pressure may be higher than the usable pressure of the component.

  • Helium recovery system,where the heliox exhaled by a saturated diver is piped back to the surface,oxygen is added to make up the desired composition,the gas is pressurized to the proper supply pressure,filtered, carbon dioxide removed,and returned to gas distribution panel, again supplied to divers.Shop compressed air is generally available at a pressure suitable for most applications,but some may require higher pressures. A small supercharger can efficiently provide this air.
