Abstract
Turbine pumps can include: an inlet port; a first discharge port; a body defining a flow path extending from the inlet port through a raceway to the discharge port; and a turbine impeller disposed in the raceway. In some pumps, the body further defines an channel providing a fluid connection between a raceway outlet and the discharge port. In some pumps, an outlet angle defined by the inlet port, an axis of the turbine, and the discharge port is between 30 and 180 degrees.
