Modeling Pumps in SSA

Can anyone assist with why there is no flow in the forcemain?  I have a lead pump that turns on at 3ft depth and off at 1ft depth and a lag pump that turns on at 5ft depth and off at 3ft depth.  Both pumps are Type-3 and I input the performance curve from the manufactururer.   Even when I change the pump to "design" there is no flow in the forcemain.

Hi William, 

 

There appears to be some issue with your Type3 pump curve. Please refer to the TYPE3 Pump Curve from Help page 284 | Chapter 7. You may want to review your pump curve, the higher the head difference, the lesser the flow should be as per Type 3 pump curve. Please refer to the revised model where the pump curve should be in that line (not to say that it is the correct pump curve).

 

Thanks,
