Looking for a ballast tank pump supplier.

[Captn Nemo]

Ahoy mates...I am looking for a new pump supplier for my ballast tanks. The pumps I used to get were from Germany and produced a flow rate of 1.8 liters a minute. I can no longer get them because the German supplier quit shipping to the US because of the tariffs. I need the high flow pump because of the large size of my ballast tank in my 58 inch sub. Does anyone know where I can get a reversable high flow pump in the US?
Thanks,
Walt

This may or may not suit the purpose but I have two planned as steering thrusters for a 60” sub.
