Sir, can you confirm impeller fitment clearance on shaft in multistage pump if the impellers are slide fit on shaft

Happy Thanksgiving to you all

Very Nice Presentation!

Thanks

Very nice system

Excellent course. Congratulations! Where can I find the course presentation?

Good learning video for Rotating equipment engineers

Great sequence of videos from Rhurpumpen

Keep going, Ruhrpumpen team!!!❤

For product cooling water high flow 15000 m3 / hr and low head 60m Suction temperature 30 deg c. Can we go with BB1 Pumps or VS1 Pump. When we go for VS4 pump. Could you please advice.

Out standing PPT , Can u explain commissioning process in LNG gas with the Pump

Nice video, it help me to understand centrifugal pumps, im focus to positive displacement pumps

Felicitaciones y que sigan los éxitos.

Thank you very much for this valuable information We would like to know the effect of changing speed (SIMILARITY LAWS ) on NPSH

Wonderful course!! Thank you very much

00:09 This session will cover the concept of npsh - a crucial and challenging aspect of pumping. 02:46 Understanding of NPSH and its impact on us 08:32 Understanding NPSH is fundamental to pump operation. 11:28 NPSH and Nss explained simply 17:39 NPSH is often misunderstood, cavitation occurs at higher suction pressures. 20:35 Maintain sensible margin to avoid raising suction pressures too high 26:21 The correction factor for pumping different fluids affects NPSHr. 29:01 Understanding the difference between NPSH and recirculation in pumps. 34:28 Impeller designs from 1950s-1980s had limitations that led to increased vibration and unstable NPSHr characteristics. 37:15 Pumps should operate at their design point for best efficiency 42:26 Incorrect assumptions can lead to equipment oversizing and poor performance. 44:52 NPSh ratio and NPSh margin are important factors in pump performance. 49:48 High density causes damaging cavitation with an SG of 1.2. 52:29 NPSH is crucial for pump operation. 57:31 Calculate NPSH available and compare with pumps in the marketplace. 1:00:06 Consider inducers for improving NPSH margin 1:05:15 Designing systems to avoid cavitation and achieve best efficiency. 1:07:43 NPSH affects impeller trimming and pump speed. 1:12:49 NPSH is based on actual liquid level or pressure above in a closed system. 1:15:20 NPSH and cavitation considerations for pump operation 1:20:28 NPSH testing and operational considerations 1:23:12 Lowering the impeller in VS6 pumps can increase NPSH available Crafted by Merlin AI.

Great video, may you put the material used in this video available on your website? I could not find

Bad sound

Wonderful explanation, thanks for sharing this video.

Wow what a great project!! congrats.

Great video and wonderful equipments

proud to be part of this great company, keep going forward.

could you please upload th full session16

The best ever introduction on Basics of Pump theory ! Well done Simon 👏👏👏

Thanks. Always wondered what it meant.

Перекрыв себе винтель. Теперь как нефть будет продавать? Море не имеет выхода,считай что озеро. А нефтепровод российский. Сколько стран насрать старались.Германия небо закрыв теперь медикаменты из Китая самолётом в обход России.В семь раз дороже.Кто выиграл? Фины теперь через три моря а не через финский залив в Балтику.Что то они выиграли? Так и Казахстан. Через море и три государства два раза перегружая.Теперь посчитайте во сколько выросла себестоимость.

Perfect session

Good information

Excellent Video ... Thank you Simon

NPSH test is generally not applicable for VS1,VS4 pumps, instead Min. Submergence test is carried out

Felicitaciones y muchos éxitos.

Felicitaciones. Excelentes productos y servicios. Saludos desde Chaco, Argentina.

It's amazing....

Good

excellent presentation.

Excellent explanation.
