Each CMBE pump carries a Grundfos integrated variable frequency drive and is delivered complete with five-way fitting, non-return valve, diaphragm tank, pressure sensor and pressure gauge. Both pumps run when a higher flow is needed to hold a constant pressure; one pump carries the load the rest of the time.\u003c\/p\u003e\n\u003cp\u003eCascade control adapts the system to consumption by switching pumps on or off and changing the speed of the pumps in operation, so the system runs with constant pressure using only the number of pumps required. Pump alternation distributes operating hours evenly — the system automatically starts the available pump with the lowest number of running hours since the last power-off. The premium-efficiency IE5 MGE motors need no external motor protection and run at 55 dB(A) or lower.\u003c\/p\u003e\n\u003cp\u003eHydraulics are stainless steel AISI 304 throughout — pump housing, sleeve, shaft, impellers and chambers — with an AISI 316 sensor fitting. CMBE TWIN is designed for flooded suction (maximum 3.28 ft of lift; not self-priming), handles liquid temperatures to 140°F, and is radio-enabled for Grundfos GO through the MI 301 module. Typical installations are apartment buildings, hospitals, hotels, small industrial plants and domestic fire suppression.\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\u003etotal head\u003c\/strong\u003e you need across the top (pressure in parentheses).
