Pump curve basics. In this video we take a look at pump charts to understand the basics of how to read a pump chart. We look at basic pump curve, head pressure, flow rate, pump performance, impeller size, efficiency, npsh, multi-speed pumps, VFD’s, rotational speed, voltage, frequency and phases to help you learn hvac, hvacr and mechanical engineering.

It's a awesome vdo
🤔
In Canada 3 phase voltage is 575v and not 480v as in the USA
enlightening
DUDE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thank you very much
Amazing Video! Thanks guys you're doing amazing job. The way you explained it is very clear and easy to understand.
But I have to disagree with an info you mentioned at 1:00 , as I know pumps don't produce pressure, they produce flow only and the pressure forms from load and friction and the pump has to overcome it to deliver the desired flow.
I really love your video , i request to you that please upload video about mechanical seal design and selection
Well done. Clear concise and well illustrated.
great job!!!!

Our company distribute water pumps in Myanmar. Distributed world wide brands are Lubi Made in India, Sea Land & Rovatti Pompe Made in Italy, Star Pompa Made in Turkey, JD & Jianming Made in P.R.C. Please join our UMC-TV(Pumps) channel for more water pumps video. Thanks for your attention. 🤗🎊
Thank you sir .
I have a question,
If a centrifugal pump flow limit is from 60 LPM to 535 LPM at 3500 rpm, does the low flow limit of 60 LPM changes with running the pump at lower rpm? Does this limit changes goes down when we run the pump at lower rpm?
How to accomdate viscosity impact on pump curve selectiin while vendor runs his pump with water?
horizontal pipe : "so no head?"
Any video for start up fixed & multi-speed pump?
Thank you…I’m civil engineer and I’m currently working water industry, I do lot of mechanical works, big pumps water treatment plant…this information very helpful to me.. cheers
Very informative. U guys are doing amazing work. Useful information. Keep sharing!!!
Dear sir.. I have amixed flow pump when i decrase the flow and pressure increase the power also (increase) what is the problem about this
Thank you Sir
Really really helpful video
How to calculate the submersible pump when I only have the power and lift height?
It's very informative with very clear explanation… thank you so much this amazing video 🤩🤩
