Dear sir,
thanks for your good cooperation and helpful files.
1- Mr.LittleInch : we can not put a sampling cap in to the truck because we want to lift the liquid from different location and also different liquid level. for example water is heavy that gasoline and deposit in bottom of tank. with...
Excuse ne my dears,
Our plant and our target is very simple ( as shown in schematic). We want to lift a liquid(oil, gas oil, gasoline,...) from the truck for sampling and its qualificatin.
For this porpose, we have to lift the liquid with PD pumps. The distanse between pump and top of liquid...
Ok and thanks again,
The teat was down with gas oil.
And in this atached schematic you can see the our plant. In fact we want to lift the oil, gas oil or gasoline from the truck for sampling. All part work ok except the pump. As i toold our pump work only 30 secends...
Dear sir
Today we test the mentioned pump(gear type) for lifting the gasoil from 3 meter. The pump lift the gasoil esely and discharge flow was good. But the pump worked only 30 secends! And after that the flow decrease to zero!
Then we stop the power and reverse it for secend. Again we connect...
Thans alot for your kinkly information and help. Today we test this arrangement again with som modification and i reflect the result here.
Thanks again
Thanks Dears
But it is impossible to use the nitrogen for increasing the pressure. We know that the maximum lifting height is around 10 meters. Why we can not lift the gasoil 3 meters?
thanks alot,
the site elevation is not too high but it seems that the pump can not wotk becuse of low NPSHA. is there any solution to incrise the NPSH in this case? or is there any pump that can work at this sicuation?
wen we fill the sucton line with gasoil, the pump works better than befor but...
Dear Sir,
i want to select the suitable pump to lift the gasoline from the Truck. the truck is located 3 meters under the platform that pump is located on it.
we try with gear type pump (that used in gas stations), but the result is not good becuse of very low flow. we can not used check valve...
dear all
i want to prepare a data sheet for some injection packages such as:
1- methanol injection package
2- anti foam injection package
3- corrosion inhibitor injection package
in all package we have mettering pump, storage tank,mixer, electrical motor and related auxillary. could you please...
Dear artisi,
As I know, in some project specification, only for parallel operating pumps, the motors shall be sized based on end of curve. I think the reason is as follow:
Please consider two same pumps are working in parallel and they pass the 100 m3/hr flow in the line. In this case each pump...
thanks all,
dear JJpellin,
my consern is not aboat the sizing of couplig, my clear question is this:
the pump manufacture sujest the 1700 KW motor for our requirment (as explaine in my thread). i want to check that this power is enough or not?
based on our rated flow, this is good selection...
Dear friends,
I want to select the suitable motor for pump. The hydraulic power as per this formula (Ph = q ρ g h / (3.6 106)) is 1115 KW
The pump efficiency is 0.73, so the shaft power is equal to (1115/0.73) = 1527 KW
As per our pump data sheet, the motor shall be selected based on” End of...
I would be grateful if someone responds to my post that they have enough information about it.Marginal issues and moral judgments are incorrect.
thanks again
thanks for your answers,
but i have to choise the pump standard in our data sheet. i khnow that non Api pumps is suitable for water application, but i want to specifiy other standard such as ANSI, HI , ...
which standard do you recommend except API?
Dear All,
- could you please help me to introduce with Non-Api pumps?
- which standard shall be referred for this pumps?
- when we use this type of pumps in Oil&Gas industry?
if you want to select the water pump in your refinery for fire fighting tank loading,which type of pump do you...
