Give us a clue as to the context...

Water supply? Automotive carburation? Rocketry? Sneakers for short people?

Yeh, just too many cats...mine was getting grumpier and grumpier,

So I found this old family photo! (I'm the tall one)

what is the functions of booster pump and how it is monitoring the pressure drop and supply water to bathrooms.

A booster pump increases the pressure in a pumping system.

Where it is used (pumping of water)

If a single pump is used In a high rise building all the water requirements of the building must be supplied with sufficient pressure to service the top story.

example: a 50 story building at 3 m /floor = 150m + storage tank 4 m.

water use = 2y units per floor.

if friction is taken at 10m the total pumping head will be 150 + 4+10 = 164m

energy = constant * 100y * 164m = c16400y (efficiency taken as 100%)

if for the same building a booster is installed 1/2 way up the power use will be

pump 1 = 100y units @ 75 + 5 = 80 energy = const * 100y * 80 = c8000y

Booster = 50y units @ 80 + 4 = 84 m energy = const * 50y * 84 = c4200y

total =c12200y ==> the energy used is about 75%.

More boosters will produce More savings.

Another advantage of boosters is that the pipe can be of lighter class.

Boost system fluid pressure due to required output levels should output pressure without the pumps be lower than required due to frictional and other losses.

My own experience with booster pumps is to supply fluid into the suction of high pressure pumps to give them a positive suction pressure.

Quite true but the pumps do not have to be close to each other.

Booster pumps can be used for practical and economic reasons.

On a construction site a pump is rated by the vertical height that it can pump. If you need to raise fluids to larger heights there are two possibilities,

1 get a bigger pump,

2 add a booster pump. The pumps in series will add their height pumping capacity

Price, space and availability make the diference.

The sketch is not accurate.

Typical booster pump usage for irrigation

Pump station

A : 4 low pressure submersible pumps.

B : 4 centrifugal booster pumps above flood line

C : 3 centrifugal booster pumps.

D : 2 centrifugal booster pumps

8 circles serviced by 3 centre pivots, irrigating a variety of crops on a rotation basis.

The rise from B to 1 is more than 40m

On the date of the image 3 pumps each was used at A & B and 2 pumps at C.

Advantages;

The pipe class could be reduced.

Energy costs is kept low.

Hope this satisfy your curiosity about booster pumps.

Going back to HydraulicS Fundamentals.

--------------------------------------

A piston pump WILL suck LIQUIDS from a Sump that is open to atmosphere.

So doing ,LIQUID will cause cavitation because Inlet will approach ZERO PSIA.

Cavitation will eat up all metal on PISTON INLET path in a few hours- unless:

A Booster pump keeps pushing liquid into Piston Pump Inlet at all times whether piston is sucking or not.

The Q-H characteristic curve of a Centrifugal pump can be fairly flat.

This makes Centrifugal the ideal AND ESSENTIAL Booster Pump type.

So that Piston Pump Inlet never experiences near- Absolute -zero pressure.

Booster pumps are supplementary pump to a system where main pumps fills the circuit and building main pressure.Once line pressure was maintained ,boosters are operating when there is a pressure drop.Pressure drop indications are set by pressure switches.These systems are used in apartments,hotels,long distance liquid handling and fire fighting.If you want to learn more contact KSB,ITT,GRUNDFOSS.
