The CF-4 1000 is a large-volume cast-iron pump for large filtration systems with a cast-iron body and pre-filter. The low-speed 1,450 rpm motor ensures quiet and wear-resistant operation – lower speed extends service life compared with standard pumps. Each unit is tested and has a registration „birth“ certificate on the back of the manual.
