US Water Systems has the Stenner 85 series adjustable PS pumps on sale right now for $336. The 85M5 is 11 to 223 ml/min which sounds about perfect for most ca reactor needs from what I am reading in other posts. Thanks for the tip. I think this makes much more sense than a used CP pump with unknown hours on it. Anybody know if the 45 series are much quieter being half the motor rpm of the 85 series?
