Biostream BP40 (4″) Fish Pump

Q: How many fish will the BP40 move in an hour?

Up to 8 tonnes per hour through its 4″ (100 mm) bore, though the rate you actually achieve depends on species, fish size, pipe run and head.

Q: What size fish will it pass?

The BP40 is rated to a maximum average fish size of 300 g.

Q: How high can it lift?

Up to 9 m of pumping head on the standard 3 hp BP40, or up to 14 m on the 7.5 hp BP40-S.

Q: How do I choose between the BP40 and the next size up?

Compare bore, fish size and tonnage together — the BP40 is 4″ bore, 300 g fish and 8 t/hr, while the BP60 is 6″ bore, 600 g fish and 16 t/hr.

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

Water and air demand figures are not published for the BP40, 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.

Q: How do I get a price?

Request a quote with the tonnage you need to move per hour, your maximum average fish size and the vertical head from water level to discharge, and we’ll confirm the right BP model and lead time.

Sizing: the BP40 moves up to 8 tonnes of fish per hour through its 4″ (100 mm) bore at up to 9 m head, with a maximum average fish size of 300 g — step up to the BP60 (6″ bore, 16 t/hr, 600 g fish) if your fish are larger or your tonnage is higher, and size on your worst case, as these limits cannot be achieved simultaneously
