Weekend project #34223.
Today im going to build a portable transfer pump i think would come in handy, mainly for camping but anything really. Built to the confines of a small weatherproof/impact resistant pelican case and with options for connecting to a 12v power source or using a 18v cordless power tool battery.
So we have the inlet up the top, inline gauze filter, through the pump, ball valve, which will also work as an on/off switch (because of the pressure switch) and back out again. The two stainless bushes are there so i can weld a bracket to them and screw to the box, eliminating any stresses from pulling on the hose etc and breaking the pump.
Here we have the pump mounted, support things fitted on an angle so the hoses dont have to kink, the 18v supply goes into a step down converter from 18 to 12v, it then links up to a 12v anderson plug for an external 12v supply, through a 10a blade fuse and to the pump. Job done!
