Determing flow of a closed loop parallel pumping system

Click For Summary
SUMMARY

The discussion focuses on determining the flow rate (GPM) of a closed loop parallel piping system, specifically addressing a scenario with a pump rated at 4350 GPM at 50Hz, which is currently operating at 4500 GPM at 37Hz. Participants emphasize the importance of understanding pressure intake and outlet to model the system curve accurately. Additionally, the conversation suggests that adding a second pump in parallel may be a consideration for optimizing flow. The intersection of the system curve with the pump curves is crucial for effective system analysis.

Hi all,

How would one go about determining the flow(GPM) of a closed loop parallel piping system.
I believe this has to do with the pressure intake and outlet of the pump as I have a pump in the mentioned system rated at 4350GPM@50Hz but it is pumping at 4500 GPM at 37Hz,

Thank you all for your time in advance.

Regards,
D

You mean you want to add a second pump in parallel? Knowing the flow and pressure - assuming it is a constant flow situation - enables you to model the system curve, the identify where that crosses the pump curves.
