Pentair Fairbanks Nijhuis BF Series BiFlow Pumps

The Fairbanks Nijhuis BiFlow pump is a bi-directional, in-line ballast / anti-heeling pump. This pump is specially designed for the transport of large amounts of ballast water, where space requirements and piping must be reduced to a minimum to ensure a high system efficiency. The configuration is completely symmetrical, consisting of two counter-rotating impellers with variable speed. The driver is submerged and completely integrated with the pump. This configuration ensures a high efficiency and controlled flow in both directions to opposing ballast tanks. The BiFlow can be installed in the double bottom section of the ship, submerged or dry. - Capacity: 4,403 - 13,208 GPM (1,000 - 3,000 m3/h) - Head: up to 98 feet (30 m) - Bi-directional operation In-line assembly - Large performance envelope - High overall efficiency - Symmetrical forward and reverse performance - Minimum of space and piping - Fast control response Low noise and vibration levels
