CME is the CM pump end with an MLE motor on top: a motor with the frequency converter built into its terminal box, so the pump varies its own speed instead of running flat out against a throttling valve. It lies on its feet on a horizontal base, which suits a plant room where headroom is short and floor space is not.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA pump curve plots what the pump adds to the pressure already at its inlet\u003c\/strong\u003e, not the pressure you will read at the outlet. On a city main holding 40 psi, a pump adding 60 psi gives about 100 psi downstream. On a gravity-fed tank the inlet contributes almost nothing and the curve is close to what you get. Size on the boost required, then let the drive hold it.\u003c\/p\u003e\n\u003cp\u003eThe CME 3 frame is rated at 16.4 GPM. The family number is Grundfos’s nominal duty in cubic metres per hour, not a GPM figure — size the pump from the rated head table below, not from the model number.\u003c\/p\u003e\n\u003cp\u003e8 models are offered, from CME 3-2 to CME 3-9, covering 3\/4 to 3 HP on NEMA close-coupled motors. Adding stages raises head at the same flow without changing the footprint. Connections are 1 in NPT female suction and discharge, and the pump is rated 232 psi maximum operating pressure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy 304 rather than cast iron.\u003c\/strong\u003e The -I build has no cast iron in the liquid path, so there is no iron pick-up into the water and no rust bloom on a system that sits idle.
