pranav,

 

Pump's NPSHR would dictate such height if other parameters, say suction vessel elevation and low low liquid level..., are to be already fixed.

pranav,

 

It depends on fluid S.G. and local atmospheric pressure For water at sea level it is around 10 meters from liquid level. Then, maximum height of suction side from the liquid level:

 

H (m)=10/S.G

2. cost of energy

 

3. pumping lift

13.12 ft

4. pump column pipe (suction line)

3-in. steel pipe

13. distance from pump to vessel

26 ft

5. system flow rate

132 gpm

6. yearly operating time

1000 hrs

7. distance from pump to pivot

14763.78 ft 3 inch PVC pipe

8. required operating pressure

15 psi

9. elevation change from pump to pivot

+49.21 ft

10. types of fittings in system

see drawings below

11. suction vessel pressure

14.5 psi
