I enjoyed every moment of this training! Many thanks!

THIS GUY IS NOT A MECHNANIC. HES JUST A ROBOT. HE DIDNT STUDIED MECHNICS, HE DONT KNOW WHAT HES DOING. HE RELLY NEEDS TO STUDY MECAHNICS TO HAVE THE MECHANIC EYE. A RELA MECHNIC WORTHS MANY DOLLARS...ROBOSTS ARE JUST CONVENIENT WORKERS, GOOD LUCK EMPLOYING PEOPLE WITH NO MECHANIC KNOWLEDGMENT.

Thank for upload it

[@adarshks674]

What do you call the material handling set up you have with remote control for moving the pump?

[@DESMIAS]

We use a remote-controlled crane by the workstation. Other options could work, as long as safety, weight and mobility and is taken into consideration and in place :-)

[@hoalbert]

Some of our brand new Desmi vertical pumps impellers are rubbing against the housing when turning the pumps shaft with hand. Any suggestions? We have a lot of Desmi Pumps in the warehouse to be installed on the ship in future. Thanks

[@DESMIAS]

Please check/ensure that the pump casing is not overloaded with forces / moments from the piping system - this might deform the pump casing and result in impeller rubbing against wear ring(s)

[@DESMIAS]

And for more information, please do not hesitate to contact us via [e-mail]

[@hoalbert]

@@DESMIAS Thanks for the info. Will email [e-mail]. No the pumps are not installed yet and it is in the warehouse for long term storage for 6 months to a year before they get installed on the ship. Part of the storage maintenance is to turn the pump shaft once a month. When turning with hand you can feel some of the pumps impeller is touching the housing.

[@Eric-sk4dj]

When fitting the impeller back over the shaft, does the mechanical seal shaft spring get compressed down over the keyway?

[@DESMIAS]

Yes :-)

[@kanwarDbulley]

No wear rings in your pumps? why no mention of clearances b/w impellor and casing. ?

[@DESMIAS]

Yes - the NSL pump has wear ring(s). Please refer to actual pump manual regarding acceptable clearance.DESMI pump manuals are found here: www.desmi.com/centrifugal-pump-manuals.aspx

[@latestbuzz5066]

Can anyone please tell me what is the exact name of that Coupling.

[@DESMIAS]

This pump does not use a regular coupling. Our model A02 is designed with a short motor bracket frame which means that we use a kind of pipe coupling which is fitted directly at the motor shaft. This design also eliminate the requirements of pump bearings.

[@latestbuzz5066]

@@DESMIAS thank you for your reply 🙏

[@rahimys6135]

Why didn’t check for shaft run out?

[@DESMIAS]

See 5:18 where we mention "check the shaft for damages" :-)Have a great day.

[@rahimys6135]

Yes i know you check the shaft for damages but should check shaft with dial indicator to determine whether the shaft is bend or not..that’s what i mean..if the shaft using component or cartridge seal, always check stuffing box perpendicularity and concentricity to ensure it’s still within tolerance to avoid seals premature failure..thanks..have a good day..

[@arifsaifi7605]

Plz upload some turbine boiler video

[@DESMIAS]

Hi Arif - thank you for your comment and suggestion, but unfortunately we do not have a turbine boiler video available. DESMI manufacture, sell and service pumps and pumping solutions. All video material is available at our you tube channel kzbin.info/door/RxHPjrgOLvBEgsDcHnq1ZQHave a great day.

[@ahmedalhashimi4922]

Could someone please clarify to me why the bearings had to be heated?

[@DESMIAS]

Hi A. Specter - thank you for your comment. The bearing is heating for easy mounting on the shaft.For more information, please do not hesitate to contact us at [e-mail]

[@ahmedalhashimi4922]

That's what I had in mind, thank you for replying.

[@lkkjhtemmexv1838]

@@ahmedalhashimi4922 iF YOU DONT KNOW THIS, this is so basic, yor wasting your time trying to learn mechnics. Obviously your are not going to do that if you want the pump to last.

[@ahmedalhashimi4922]

@@lkkjhtemmexv1838 Nobody is talking to you, and perhaps you should spend less time on KZbin, and more time learning how to spell correctly.

[@davidmarchanvasquez4600]

what kind of coupling is it ?

[@DESMIAS]

Hi David. The easy answer is Monobloc Coupling and this of course comes in various sizes. You can read more about the NSL pump and the coupling here: www.desmi.com/desmi-products/nsl-centrifugal-pump.aspx
