For buried storage tanks, what should be done if the pumping distance is not sufficient?

What should be done if, in the case of buried storage tanks pumped with a pump, the suction lift is insufficient (the tank is 5 meters deep)?
Increase the pressure in the storage tank; select a pump with a high net positive suction head
The main issue is that it’s not possible to find a pump with such a high suction lift, sir!
It can be pumped up using a self-priming pump. Or inflate and punch inside the tube
Pumps are connected in series to increase the pressure difference, which can solve most problems; however, it depends on the working medium
Use an submersible pump, use a subsea pump, or use nitrogen to push it
What medium? A sliding vane pump is used, with a suction height of up to 9 meters
:Should a buffer self-priming tank be added before the pump? I’m not sure what it’s called where you are; it involves using a pump to fill the tank, so that vacuum is created and suction occurs. Fill the tank for the first time by using the pump
Buried tanks are generally used for storing dirty oil or waste liquids, and there are specific requirements regarding the pressure in such tanks; it is not advisable to employ pressure-boosting measures. It is recommended to consult the submersible pump manufacturer to see if the medium and operating conditions meet the requirements.
Sir, I’d like to know what the pressure requirements are for such buried tanks. Thank you!
