Eifel ISO2858 Standard Horizontal Single Stage Centrifugal End Suction Pump for Building Services
This pump goes above and beyond the ISO 2858 benchmark. Thanks to its refined hydraulic engineering, it achieves superior efficiency with lower power consumption—meaning you get more performance for less energy cost. In fact, it delivers 1.6× the flow and 1.25× the head compared to standard ISO 2858 pumps of the same size, giving you a significant performance edge without upsizing your equipment.
