Hi Guys,
I have a query.
- What is the BS standard (Latest edition) to be used for compliance for Chemical process centrifgual pumps and Positive displacememt pumps?
- Is the API standard for centrifugal and Positive displacement superior in terms of design and specifications? (Meaning, can an...

Hi Guys,
We are under a big dilemma now. Need your kind inputs please.
The submersible pumps ordered is to be cooled using pumping fluid which is ambient temperature. Although we can also supply external water (continuous flow) & filling the cooling shroud to cool the pump motor.
Now...
Hi Guys,
I need your advise.
I am doing an apple to apple comparison of Mixed flow Vertical line-shaft pumps.
Duty conditions are 4,400m3/hr @ 15m, 2,500m3/hr @ 30.3m
Based on the motor specs compliance of 1.15, the motor rating turns out to be 500Kw / 8 POLE for the Manufacturer A.
However...
Hi Guys,
I have a PD pump (Internal Gear) with Cast Iron construction. As the understanding goes, the nozzle loads (Forces and Moments) are not compliant to API-676.
The pump footing lies on the bkt which is offset from the pump casing by 400mm. Now, the piping is already fabricated based on...
Hi Guys,
I have few doubts and new your advise. Am referring to PD Pumps (Internal Gear)
There was this question from my customer which am not getting a satisfactory reply from the manufacturer.
1. What does dynamic load imply to PD pumps?
2. How to calculate Dynamic load?
Thanks in advance.
Hi Guys,
From the acceleration head formulae, Ha = LvnCSg / 2.31Kg (ft)
is the "L", just the the total length of pipe from suction tank to pump suction flange?
Or
‘equivalent length of straight pipe factoring all the friction loses on elbows, Tee joints, valves & fittings etc’.
I don't get any...
Hi, I have another query. Need your opinion.
Suction side: If I need to install Inlet stabilizer, Should that be: pump suction flange -> Inlet stabilizer -> Expansion joint OR Pump suction flange -> Expansion joint -> Inlet stabilizer?
Disc side: If I need to install pulsation dampener, should...
Hi Guys,
I need your opinion. Is AODD Pumps "With Inlet stabilizer placed next to the pump Inlet" suitable for Low NPSHa (typ 0.5m)? had you come across this before?
Hi Folks.
I need your advise.
Does using (Inlet stabilizer / surge suppressor / tranquilizer / pulsation dampener) on the suction side of the pump reduces the calculated acceleration head? If Yes, can we quantify it by using any equation / formulae?
Hi guys,
Does anyone know about the file types in Intralink cache folder. Those follows as WFCONT file, STATE_LOCK File, etc etc.
Please check the attachment. Are these files editable & whats the usage of all these. Every time, I check-out or open a file in workspace, I see a lump of files...
Hi guys,
I am using pro/E WF4.0, Intralink 9.1.
I had checked out a large assembly to my workspace, opened in simplified rep & was working continuously.
Suddenly I encountered this pop-up box stating "The server is currently unavailable. Do you want to switch to offline mode". I clicked No...
