Purpose of Booster Pump

What is, "intdbfp"?

You can do anything your boss permits you to do. We are certainly not going to stop you here. Here you can make up new words, intdbfp, that have mysterious meanings. Now I believe a booster pump is a pump that changes some parameter of fluid motion but to less of an extent than the main pump. This design approach could be for any of several important reasons:

• The fluid has lost too much of this parameter to be effective in the next job.
• The circuit branch with this booster pump requires a different level for this parameter than what the main pump provides the rest of the system.
• The parameter level needed cannot be produced in just one stage.

Any of these reasons that I dreamed up and several more that I didn't think of could explain why you use a booster pump in your system.

Now you will notice that I deliberately used nebulous terms like parameter and fluid in my plausible explanation. This is because I do not know anything at all about these items to help you solve your problem. I use to ask the OP to come back with more information but so rarely does anyone return with useful information that I've come to a different conclusion. Most people who ask these kinds of questions come here with all of the information they can grasp of the situation looking for help. They use their subsection 1d10T exception clause to bring their problem to us. (We all have used this exception at one time in our lives. We're all human here. Beep. ) If you wish to provide us with more information about your system, I'm certain somebody here may help you. Or you could just bypass your booster pump and install a bigger main pump to see what happens.

Good Luck

To begin, I assume by 'intdbfp' that your fingers got crossed-up on the keyboard and you meant to type 'omyfng['.

You don't provide any details about your system, so any answers you get are likely to be pure speculation. So here goes, 4 quick ones just off the top of my head:

1. Your system doesn't have enough electrical power available to support a larger main pump, but it can support a booster pump down stream.

2. The pipes cannot support the stronger pressure from a larger main pump.

3. A larger main pump would need to be fed by a booster or priming pump anyway, so their is no gain in having a higher capacity main pump.

4. Plans for future growth makes using a booster pump a better long-term alternative.

What's "omyfng["?

the word is "booster" means to boost up/increase. What to increase ? pressure not flow!

Based on the information provided (or lack there of) and the way the original question was written I suspect that "chalkpiece" is from/in India or Pakistan.

I also suspect that he or she is really meaning a "Jockey Pump" normally associated with a fire water loop system to maintain pressure without running the main Fire Water Pumps.

Just a thought.

TWDHSS? <S, C>

The booster pumps are placed ahead of BFP in thermal power stations to ensure that sufficient NPSH is available to BFP and thereby avoid cavitation (you must be aware that the condensate is at negative pressure)

UD15

These booster pumps are placed ahead of the primary pump to maximize flow rate. In this case cavitation is not a problem.

yes boss, i asked about power plant only,,,,can u please expalin it elaborately,,,,

Where did you say anything about a power plant?

I guess this comes under the realm of poor English. Well allow me to post the pertinent part of the FAQ on the rules for posting.

Provide as much information as possible. The most frustrating questions on this site are like this: "I need a sensor to test water flow - which is the best one." What are you testing for, what are you trying to determine? Is it in a stream, a pipe, an aquifer? Are you looking to measure velocity or mass? Are you testing for particulates, mineral concentration or pollution? Is it wastewater, potable water, slurry, etc.? The more you let us know, the better the chance that someone on the site will be able to help you find an answer (thanks Silas Marner).

This rule exists not only so that we can understand what you are asking but so we can also understand your language skills and technical expertise.

Now allow me to add my own personal caveat. Power plants are very dangerous environments. If you do work at a power plant, you should not be asking us about the details of your plant's design without demonstrating what you do understand about your plant's design. If you are lucky a little misplaced knowledge in this environment will only shut down the power plant and cost you your job. If you are unlucky you could kill many people. Nobody here wants to see another Chernobyl disaster. If you do not work at a power plant then you must still explain how much you understand of this process so we can offer a useful explanation. Requesting a more elaborate explanation when you offer so little comprehension seems very dangerous and disrespectful.

The BFP is a high RPM pump and hence more prone to cavitation if sufficient NPSH is not maintained.

One way to generate this NPSH is to move de-aerator up and the gravity will provide the NPSH. However as you may see that for the huge flow requirement the height required will be enormous.

The better method is to put a low RPM pump feeding to the BFP which will be more tolerant to low/ negative suction head at the pump inlet.
