3D Printed Centrifugal Pump - Designed with a closed vane impeller and a suction eye to accommodate a standard UK 2 litre bottle. The coupling was designed to fit a 3.2mm RC motor shaft but by using a longer (150mm) coach bolt it can also be used with a drill.

Whilst testing at 1800RPM the pump has a capacity of 13litres/min at around 0.9m. It's maximum pump head is 1.2m.
