Small DC Pump
Small DC Pump
(OP)
All,
I am working on an application/product where I would like to use a small DC (6V) pump, capable of < 1/2 GPM flow, with about 5' of head. I have looked at some aquarium pump manufacturers, but they are all 110 VAC. This application is going to be remote battery operated with solar trickle charging, intermittent operation. Any suggestions would be helpful.
Regards,
Rich.....

Search Micropump's website and catalogue. You should be able to find this stuff on Google.

I happened to be working similar problems (sitting for the P.E. this month). I've attached an excel worksheet for you to play around with if the numbers change a bit.

Inputs (in yellow): head required, voltage, GPM, pump efficiency, specific gravity. It calcs things like: mass flow rate, Watts required, hp required, amperage required, and wire size to go with the particular load.
I just wanted to make sure you could get 5 feet of head from the 6 volts. Of course, it depends on the current, so you can see that the current draw isn't too bad 78mA requiring 32 gauge wiring or better.

Thanks. This is exactly what I was looking for. Good luck with the PE exam. One word of advice, take along a bottle of Excedrin and/or Tylenol, because afterwards you are going to have a headache.
