Then the only PD pump I can think of is Progressive Cavity pump for this application bcz of some solid particles present in the slop. So no matter how complex it will be in portable configuration, we will have to go for it. Screw does not like solid particles as I know.
For a centrifugal pump...
Artisi, thanks. So what do you think, how to manage minimum flow line if we use CF portable pump on Kerosene like products?
littleInch, thanks again. I took Vapor pressure numbers from MSDS and data sheets of main transfer pumps. The tanks have floating roofs, I checked the drawings.
I have...
LittleInch,
Thanks again, I agree with you. Other than AODD, next option for condensates is as what you mentioned. How about kerosene type products where we have about 10 m of NPSHA, can we use a centrifugal pump? Discharge side head head will be varying depending on the distance and level of...
georgeveghese, thanks for taking time and suggesting Wilden T20 AODD. Our tanks dia are in the range of 60-80 meter and the liquid level to be removed is about 1.5 m, making it 7500 m3 volume. So with an average flow of 30 m3/h would take around 10.5 days to empty the tank. That too if the pump...
Artisi, thanks. A vacuum assisted self-priming pump I think is not safe and suitable for our application bcz while initial priming, lot of HC vapors plus air mixture will be ejected which is an explosive mixture. Secondly, while pumping it continuously require higher NPSHa than what is actually...
Thanks for the reply LittleInch. I think you got a good idea of what our issue is. We use AODD which give low flow rate around 20 m3/h so it takes many days to empty the tanks remaining volume. The AODD pumps at this duty has reliability issues as well which also adds to the time.

Hello Dears,
Please advise what type of pump/pumping system is best for the following duty. Kindly share your experience as well.
Vendors please if you can offer a solution.
We need to often decommission large size hydrocarbon product tanks for inspection by transferring liquid from one tank to...
