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.
