Hi everyone,
In the API 617 turboexpander data sheet format,Single/Double/Triple port buffered labyrinth seal has been specified while in the body of this standard there is no clear schematic to show these type of seals.
It would be appreciated if someone can provide me a simple schematic of...
Dear LittleInch,
Thank you for your reply.
For more information, please refer to the schematic attached to this thread.
1- Min start Level= wetted lower bearing
2- NPSHR level at 3% head drop [it is already clear]
3- Pump-down level at head drop (at rated flow)
4- Minimum pump-down=loss of...
Dears,
I have received an NPSH curve from a cryogenic submerged pump Vendor in which a pump-down curve has been also provided (please refer to attached file for similar curve)
The pump is a propane cryogenic submerged type installed in a column inside the LPG tank and sends out the propane from...
Hello all,
I'd like to know how the Flange rating of centrifugal pumps is calculated based on MAWP (Maximum Allowable Working Pressure).
Moreover, as you know the hydro-test usually is performed at lower temperatures than design or operating temperatures.
How the hydrotest pressure is...
Hello All,
I am working on a project in which our client has requested us to provide thermal insulation for some high temperature centrifugal pumps such as steam condensate pumps to save the energy and as personal protection.
does anyone have experience with this type of insulation for...
Dear friends
Thank you all for your help and reply
Here I mention the process condition and the specification of the selected pumps by the vendor:
First proposal:
Head: 45 m Capacity: 12 m3/h
Pump model: CP-25-225
Impeller sizes: Max= 250, Rated= 187, Min=170
Second...
As you know, the pump manufacturers supply their pump performance curves with nominal minimum and maximum impeller diameters and some diameters within this range for a particular model.
I received one proposal from a manufacturer in which a pump model had been selected for our process condition...
