Chiller pump reccomendation

[Acrofiend]

Hi I have a chiller rated for a flow rate of 100-160 gph and need a pump recommendation. I have about 4ft of 1/2" ID tubing going into the chiller and 4ft going back.

Have similar head heights and flow requirements for my 1/10 HP jbj chiller and the Sicce syncra silent 1.5 has worked very well for me. Maybe the 1.0 is all you need

The min/max flow rate for the 1/10hp is 240/960 gph to give you and idea. Maybe you should even consider the 0.5 syncra pump

My main question is do I calculate the head loss totalling 8 ft of tubing? Or only from pump to chiller?

here’s a good article. In short yes you do factor in the total tubing distance but lift distance is factored in differently than return line distance.

Most pumps are listed with GPH (gallons per hour) flow rates to give you an idea of how much water they will move, however this number is with zero head pressure. In reality, most aquarium return pumps have a good amount of head pressure against them, so the flow rate at zero doesn’t necessarily...
