Finding the maximum power on the power curve and flow rate at BEP

[Paulus_]

Attached is the pump pereforamnce link of Tesk SVM(T)120-30 vertical Multistage Pump.

Assist in determining the the following:

1) maximum power on the power curve and flow rate at BEP
2) What is the correct forumala for BKW of pump


Kind regards

Hi,
A google search:

https://pumpbasics.wordpress.com/2018/09/20/typical-pump-performance-curve/

Edit:
Draw a vertical line at Q=120 m3/h and read all the relevant data at the intersection with the curves.
You can use the calculation provide in the link attached.

Thank you for your swift response Pierre.


Quick question, so the maximum power on the power curve is the BKW (shaft power)?

 

[LittleInch]

If you use the graph it's about 25.5 kW.

The little table though says 27.6

Powers Q x Hx SG / (367 × eff)

kW, m3/hr, m eff as a fraction.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
