Double Closed Impeller Centrifugal Pump - AirBus Design

Last crawled date: 2 years ago

The key points I want to address with this pump are Low Cost, Simplicity, Reliability, Weight, Flow Rate, Size and a unique double closed impeller solution adding self-priming features as well as increased pressure throughput.

Pump should be orientated inlet port down, to saturate the bottom impeller chamber to enable self-priming.

Additionally, it was designed to be aesthetically pleasing with a spiral flow chamber (which is not entirely needed) but does provide some stylistic flare to a mundane competition. (may as well have some fun with it)
Professional renders were also made to satisfy the promotional and marketing intentions of the competition.
