The CF-4 2500 is the most powerful model of the CF-4 range – a large-volume cast-iron pump for the most demanding filtration systems, with a cast-iron body and pre-filter. The low-speed 1,450 rpm motor delivers quiet operation and reduced wear, thereby extending service life compared with standard pumps. Each unit is tested and has a registration „birth“ certificate on the back of the manual.
