A centrifugal pump for transporting fish, the centrifugal pump having an axially directed inlet, a radially directed outlet, and an impeller, the impeller comprising:
- a base that is concentric relative to a rotational axis of the impeller;
- and
- an impeller body formed as at least one oblique cone having an eccentric apex and a smooth outer surface, the at least one oblique cone extending from the base.
A pump for transporting fish, the pump having an impeller with an impeller body, wherein the impeller comprises:
- a concentric base relative to a rotational axis of the impeller;
- and
- an oblique cone having an eccentric apex, at least one ridge, and a smooth outer surface, the oblique cone extending from the base, the rotational axis extending through the oblique cone,
- wherein the at least one ridge spirals down from the eccentric apex to the base.
A pump for transporting fish, the pump having an axially directed inlet, a radially directed outlet, and an impeller, the impeller comprising:
- a concentric impeller base relative to a rotational axis of the impeller;
- a tapered impeller body extending from the impeller base, the impeller body forming an eccentric apex and defining a smooth exterior surface, the rotational axis extending through the impeller body;
- and
- two vanes extending from the impeller base toward the eccentric apex,
- wherein the two vanes are provided at diametrically opposite positions on the impeller body.
