Booster Pump Use

Used to boost pressure...Pressure too low...

You don't specify if your process is high or low pressure in nature. It does make a difference if you're trying to induce pressurization or vacuumization.

If I remember correctly (always a question) a booster pump would be the first of a two-stage operation in which two pumps are in series. The 'booster' pump is used to either boost or reduce pressure before the second pump kicks in and completes the process of reaching the desired pressure range.

There is no hope for mankind.

Booster pump - Wikipedia, the free encyclopedia

Your application is "Pressurized water distribution" call it short-term boosting system.

Processing machines have dictated required pressure as 3.0 ~ 3.5 bar (43.5 psi ` 50.75 psi). Every 27" water column = 1 psi or every 2'-3" = 1 psi. So 43.5x 2.3 = 100 ft head ~ 50.8 x 2.3 =116.7 ft head. Now this means that the bottom of your overhead tank needs to be minimum this head which is not possible so from your overhead tank you cannot get the required psi/head. The supply line then needs a pump (boosting) to develop a pressure 3~3.5 bar to supply the machine (boosting). You then need a separate pump on each machine engineered both for flow m3/hr and pressure. You can have a a centralized system too with a Pressure Vessel and sets of pumps to take feed from underground tank and give pressurized 3.5+ bar on the entire waterline distribution system. this then eliminates your overhead tank usage. All my designed system have this Boosting/Pressurized water distribution system centralized network with NO overhead Tank ever need/constructed. For wash Rooms/utility the branch line supplying as a PRV to reduce pressure to desired level, rest each machine are getting their dictated flow (as per designed size of pipe diameter) and pressure 3.0~3.5 bar.

If the pressure of water not enough in upper floor of a house they use an in-line booster pump to increase the pressure.
