Well there has been talk about a dual stage pump but I am not sure if any one has done it but it was necessary for me in my next model hand held compact and very powerful almost supercannon powerful
Well here it is pictures posted separately due to size.some viewers may have to scroll sideways due to the large images and this stretches out the text.

Re: Dual stage pump Volume & Power
Pump in neutral position
First action volume dia 1"
Second action pressure dia 3/4"
First action volume dia 1"
Second action pressure dia 3/4"

Re: Dual stage pump Volume & Power
I'm not sure this will act as you intend. What I can see happening, is when you compress the pump, the strokes will go the 'wrong' way - the smaller part will move first, then the larger. Or am I missing something here?

Re: Dual stage pump Volume & Power
It looks like you have the idea backwards to me, but I could be wrong. Is the part with the tee the pump handled? Then the pump's fine. If not, it's backwards.
The problem was likely in the orientation: Usually, we present homemade parts with the end on left and the nozzle on the right, as it looks like you, adronl, did with the supposed firing valve section on the right. We just assumed that the pump's orientation matches the valves, which it appears to not.
The idea is that you nest a smaller pump inside a larger pump. This way, you use the big pump when the pressure is low and the small pump when the pressure is high. High pressures create more force on larger areas, so a smaller pump avoids this.

Re: Dual stage pump Volume & Power
If you notice the smaller pump with the T is the handle and that isnt actually a T it is a 3/4" to 1/2" threaded clip on T that you can put a handle on later and I will. Also if you look closely it is exactly as the diagram drench put up. On the smaller pump action there is a 3/4" male and female adapter so that when getting to higher pressure the smaller pump doesn't just pop out as you push. When you are ready for higher pressure you unscrew the smaller pump and go at it.

Re: Dual stage pump Volume & Power
Good. At first I thought you did have it backwards; then I thought that if the tee part was the handle, it would all make sense. It does now.
That screw idea looks good. It keeps the small pump in place until you need it.
