Hi all,
I have a problem on my hand:
I have chilled water project with primary and secondary pumps. The primary loop consist of Three small pumps to ensure that the three chillers we have never starve for water. Each pump is about 15 HP. Now the secondary pumps consist of two on duty and one stand by pump. Each pump is about 50 HP and can push up to 1300GPM. The problem I have is that the water coming from the chillers to the secondary pump is arriving at 65 psi but the pressure at the pump outlet is dropping to 25-30 PSI. This means that my project is getting chilled water at 25-30 PSI which is too low because my highest point of demand is at 35 meters and I need about 60PSI to get it up there. The reason the pressure is high at the inlet of the secondary pumps "I would presume" is because the primary pumps are pushing the water at this PSI. How can I get the pressure to the net work to go up?
