The CF-4 300 is a large-volume cast-iron pump ideal for large filtration systems – the body and pre-filter are made of cast iron. It stands out with its low-speed 1,450 rpm motor, which delivers quiet operation. Lower speed means lower noise and wear, and therefore a longer service life compared with standard pumps. Each unit is tested and supplied with a registration „birth“ certificate listing the measured data on the back of the manual.
