Biostream BP25 (2.5″) Fish Pump

Q: How many fish will the BP25 move in an hour?

Up to 4 tonnes per hour, though the rate you actually achieve depends on species, fish size, pipe run and head.

Q: What size fish will it pass?

The BP25 is rated to a maximum average fish size of 95 g.

Q: How do I size a fish pump for my harvest?

Work from three numbers together — the tonnage you need to move per hour, the maximum average fish size, and the vertical head from water level to discharge. The BP25 covers 4 t/hr, 95 g and 7.5 m, but those limits cannot be reached at the same time, so size on your worst case.

Q: What pipe size does it run?

A 2.5 inch (63 mm) bore, which is what the BP25 designation refers to.

Q: How high can it lift?

Up to 7.5 m of pumping head on the BP25.

Q: How much water and air does the pump need?

Water and air demand figures are not published for the BP25, so ask Fresh By Design to confirm the service requirements for your layout before you design the services.

Q: Can it be left permanently installed?

Yes, it can be installed as a permanent centralised transfer and harvesting system, or moved between tanks as required.

A fish pump for moving small fish gently between tanks, ponds and vehicles.
