Do you run any chems through your pump Barry?
Same pump as used in Grippa tank system. Rate it over shurlfo. Much smoother operation.
Going by the spec it's a 6 lpm not 5 lpm pump so I assume that's the main reason why the flow seems different.Same reason I suppose why when I'm using an 8 lpm chem pump. I decided to put a contoller on it as wanted to have full control of the flow as the flow was too high for my needs.
Cheers Ian, sounds like a good pump
