Online software for calculating and selecting pumps is currently designed to select a building water pump. In this program, the pump is selected for you in three ways:
Pump head and flow calculation software
Section 1 How to select a pump works as a catalog, ie you can choose the pump for yourself by using the head in meters and flow in gallons per minute. The calculations in this section are accurate because no special process takes place.
In parts 2 and 3, the software is basically the calculation of the head and flow of the pump, ie the flow (required amount of water or discharge capacity) is calculated using the number of equipment, and the difference is in the calculation of the head (pressure drop of the piping system)!
In the second part, when you do not know the material and size of the pipes, you have to select the head and flow by finger, so that by entering the floor area of your apartment and the height of the building, you can select the head and flow plan using formulas and standards. Granfos calculates with the thumb and forefinger and as a result introduces the work of the pump to you!
But if you know the material and size of the pipes of your plumbing system, you can choose the material, size and length of the pipes of your building in the third part of the specifications, in paragraph 3 of the head, using the information of your plumbing system, to calculate completely accurately. And the reference of calculations in this section is Ashri handbook.
If you are looking for Pentax pump selection software, you can choose your own pump.
Please introduce the online calculation and pump selection software to your friends.
