Abstract
An aquarium filter tank pump has a housing with a large upper portion and a small lower portion joined by a transition. A motor driven impeller generally conforming to the inside of the housing draws water into an inlet in the bottom of the lower portion of the housing and discharges it through a generally tangential outlet tube extending from the upper portion and containing an adjustable flow constriction control. A bypass tube extends downward from an opening in the transition so that restriction of flow through the discharge tube controlling pump output is balanced by flow through the bypass tube.
