Note: The impeller design has a major flaw making it useless in a centrifugal pump. The center must be hollow to allow intake flow.

A centrifugal pump intended for a DC motor to mount to. I designed this ultimately to flush the heater core in my car. The barbed fittings are sized to fit 1/2" ID vinyl tubing.

I'm not sure whether the twisted turbine blades affect the function at all but I thought they looked cool.
