Work: Battery Powered Household Pump

In 2011, I worked on a project for a national brand of marine pump products that was looking to expand into the household market using their existing, proven pump technology.

They came to us with some preconceived notions of how much performance they would get with existing pump and battery selections versus their hypothetical use case.  Experiments and benchmarking showed that likely performance would be far short of what their marketing research suggested would sell.  Beyond the need for a larger battery, they needed to provide a larger pump head for household use than for marine use (picture pumping out a basement versus a dinghy).  We came up with multiple new configurations using their existing technology, and breadboarded proof-of-concept systems to show that they delivered.

After that, my colleagues generated a rugged, user-friendly, stable industrial design, that could be thrown into the flooded space and left to do its job.  Implementation of this as a part-waterproof, part-immersed housing with low cost parts and a minimum number of tools was a fun challenge.

I never bought one, and the project ended short of completion, partially because my former employer shut my office down, but the end product still looks like what we were working on.  Hope everybody that bought one liked it.  Unfortunately, it’s no longer available.
