The CF-4 750 is a large-volume cast-iron pump suitable for large filtration systems – with a cast-iron body and pre-filter. The low-speed 1,450 rpm motor guarantees quiet operation; lower speed means lower noise and wear and a longer service life compared with standard pumps. Each unit is tested and supplied with a registration „birth“ certificate on the back of the manual.
