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.

Good video. Small criticism no soft jaws in vice plus quicker with impact gun to remove bolts etc.

@Eric-sk4dj 5 лет назад

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

@DESMIAS 5 лет назад

Yes :-)

@kanwarDbulley 5 лет назад

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

@DESMIAS 5 лет назад

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

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 3 года назад

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)

And for more information, please do not hesitate to contact us via desmi@desmi.com

@hoalbert 3 года назад

@@DESMIAS Thanks for the info. Will email desmi@desmi.com. 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.

@adarshks674 2 года назад

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

@DESMIAS 2 года назад

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 :-)

@arifsaifi7605 5 лет назад

Plz upload some turbine boiler video

@DESMIAS 5 лет назад

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 ru-vid.com/show-UCRxHPjrgOLvBEgsDcHnq1ZQHave a great day.

@rahimys6135 5 лет назад

Why didn’t check for shaft run out?

@DESMIAS 5 лет назад

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

@rahimys6135 5 лет назад

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..

@latestbuzz5066 3 года назад

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

@DESMIAS 3 года назад

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 3 года назад

@@DESMIAS thank you for your reply 🙏

@ahmedalhashimi4922 6 лет назад

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

@DESMIAS 6 лет назад

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 desmi@desmi.com

@ahmedalhashimi4922 6 лет назад

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

@lkkjhtemmexv1838 5 лет назад

@@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 5 лет назад

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

@davidmarchanvasquez4600 6 лет назад

what kind of coupling is it ?

@DESMIAS 6 лет назад

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
