The CF-4 400 is a large-volume cast-iron pump for large filtration systems – the body and pre-filter are made of cast iron. The low-speed 1,450 rpm motor ensures quiet operation; lower speed means lower noise and wear and a longer service life compared with standard pumps. Each unit is tested and is supplied with an enclosed registration “birth” certificate on the back of the manual.
