The vertical CR stands upright with its ports in line, which suits a tight floor plan under a high ceiling. The CM lies horizontal on its feet with the suction on the end of the pump, which suits the opposite: a plant room where headroom is short and floor space is not. The motor is close-coupled on one shaft, so there is no coupling to align and no baseplate to grout, and both ports are NPT female threads, so nothing has to be ordered alongside the pump.\u003c\/p\u003e\n\u003cp class=\"cmh-p\"\u003eWe supply the full CM 3, CM 5 and CM 10 range in the correct US 60 Hz build — 168 part numbers across three frames and all three material grades, in AQQE or AQQV seals.

If several outlets running together make the pressure sag, the system is short of flow and a larger frame fixes it.

AQQE uses EPDM and AQQV uses FKM, both with carbon against silicon carbide faces. On the stainless builds AQQE is rated to 248 °F against 194 °F for AQQV, so EPDM is the standard water seal and FKM is for mineral oils, fuels and liquids that attack EPDM. On the cast iron build both seals are 194 °F. The tallest stacks in each family also fall back to 194 °F on AQQE.\"}}, {\"@type\": \"Question\", \"name\": \"Will a bigger CM give me more pressure?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"It gives more flow at the same head, which is usually the real problem. If several outlets running together make the pressure sag, the system is short of flow and a larger frame fixes it. If one outlet alone is weak, head is what is missing and a taller stack in the same frame is the answer. Stepping up a frame to cure a pressure complaint is the usual mis-buy.\"}}, {\"@type\": \"Question\", \"name\": \"Is the curve the pressure I get at the outlet?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"No. A pump curve plots what the pump adds to the pressure already at its inlet. On a city main holding 40 psi, a pump adding 60 psi gives about 100 psi at the outlet. On a gravity-fed tank the inlet contributes almost nothing and the curve is close to what you get.

What changes is corrosion resistance. The molybdenum in AISI 316 resists chloride pitting, which 304 does not, so the -G build is the grade for softened, brackish and chloride-bearing water. Where chlorides are not the issue, the -I build does the same hydraulic job for less.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background:#E1E3E6;border-left:3px solid #B8BDC4;padding:8px 14px;font-size:11.5px;color:#4A4A4F;margin-top:14px;line-height:1.5\"\u003eGenuine Grundfos equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier.\u003c\/div\u003e\n\u003cdiv class=\"gs-sec\"\u003e\n\u003cdiv class=\"gs-h\"\u003ePerformance — Will It Do What You Need?\u003c\/div\u003e\n\u003cp style=\"font-size:13.5px;margin-bottom:10px\"\u003eFind the \u003cstrong\u003ehead you need in feet\u003c\/strong\u003e and pick the model that meets it at 52.8 GPM.
