Description<\/h4>\n
\n
Vertical multistage electric pump for high temperatures, up to 130\u00b0C. Specially designed for feeding water boilers.<\/strong><\/li>\n
The pump is equipped with flanged offline ports.<\/strong><\/li>\n
Compact, monobloc<\/strong> design with rigid coupling<\/strong> to a standard high-efficiency motor, in accordance with IEC standards.<\/strong><\/li>\n
Impellers are made of 316 stainless steel<\/strong>, offering superior rigidity and excellent resistance to oxidation, corrosion, and limescale buildup thanks to their outstanding chemical properties. The pump casing is constructed from 304 stainless steel<\/strong>, while the suction base and discharge casing are made of GG-25 grey cast iron.<\/li>\n
The impellers are equipped with drag cores to enhance mechanical strength and, consequently, improve hydraulic efficiency.<\/li>\n
Very quiet operation,<\/strong> achieved through a shaft supported at four evenly distributed points along the assembly.<\/li>\n
The unit is equipped with 2RS deep-groove ball bearings<\/span><\/a>, lubricated for life.<\/li>\n
It features a bellows mechanical seal, independent of rotation direction, in compliance with EN 12756.<\/li>\n
Suction and discharge ports:<\/strong>\n
\n
For VM-U 10 models, 1 1\/2″ G suction port; 1 1\/4″ G discharge port.<\/li>\n
For VM-U 16 models, both ports 1 1\/2″ G.<\/li>\n
For VM-U 20 models, 2″ G suction port; 1 1\/2″ G discharge port.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
