The CF-4 550 is a large-volume cast-iron pump intended for large filtration systems with a cast-iron body and pre-filter. Thanks to the low-speed 1,450 rpm motor it operates quietly – lower speed brings less noise, wear and a longer service life compared with conventional pumps. Each unit is tested with a registration „birth“ certificate on the back of the manual.
