Chiller with 7.6m( ID:5/8") hoses was hooked up to a CMP tool. Due to high back pressure, desire flow cannot be achieved. Low pressure, high flow and vice versa.
Pressure from chiller and 15.2m hose (return + supply) was 28psig and CMP tool contribute about 47psig i.e total pressure of 75psig and flow of 6.1gpm.
Need to achieve 7.5gpm @ 50psig. Chiller supply and return port was hooked up to a Parker 3/4" Qick disconnect.
Kindly advise actions require to achieve desire flow of 7.5gpm. Thank you

I do not have the pressure drop charts handy, so I cannot tell you specifically if you can reach your desired output. However there is a pressure drop due to friction generally listed per 100' foot of travel through the hose. By increasing the diameter of the outlet hose you will reduce the friction loss and the back pressure it caused you also have an effect due to the effect of gravity generally desrcribed as elevation (how much you are trying to raise the water from the pump ouitlet). Try to locate the pump so that it has the least amount of elevation to overcome.

bigger hoses and/or use two chillers connected in parallel
