Gear Pump

Gear Pump with mountable housing

Hey folks,

This is one of my first projects that I had to create while studying at the technical college.

The gear pump has a rotating and a driven axle (red), which are mounted in brass press bearings (white).

The housing cover and drive axle are sealed by two seals that I printed in the model with black flex filament.

After completion, I tested the printed pump, it is even pumped, however, far less than previously calculated.

This is probably due to the greater deviation than in a CNC machined, on the other hand also to leaks in the drive axle.

The pump is therefore rather intended as a model.

have fun cheers,

Steffen ;-)

Notes:

The case and lid were printed in blue with the best possible resolution and 10% infill.

The drive part, such as axles, gears in red with a resolution of 0.2mm & 10% Infill. Press bearing in white with 0,2mm & 15% infill.

The seals (frontplate and drive axle) were printed with black flex filament in 0.2mm and 100% infill, as they are very small and optimally durable for the model purpose.
