Screen wash Mixing pump

Screen wash Mixing pump

Screen wash Mixing pump

(OP)
I am reverse engineering a screen wash system (our supplier has gone bust). I need to identify a mixing pump that is powered by the high pressure water supply, that draws in anti-freeze and mixes it with the output?
Any ideas?

RE: Screen wash Mixing pump

Some data would help.  Pressure of the high pressure water, flow rate of high pressure water, flow rate of anti-freeze, outlet pressure, etc.  Do you mean a pump or an eductor?  It's a little unclear what's going on to me.

Good luck,
Latexman

Hi Latexman,
The water is supplied a 3 bar, and mixed 3:1 with anti-freeze.
The fittings are 3/8 BSP.
The water drives a double piston crank, which drives the anti-freeze pump. It is not an eductor, but like an eductor has no other power supply.

RE: Screen wash Mixing pump

After the 3 bar water loses it's energy to the double piston crank/antifreeze pump, is it the same "exhaust water" that is mixed with the antifreeze or is there a second stream of water involved?

Good luck,
Latexman

RE: Screen wash Mixing pump

Very interesting!  Thanks for sharing.  There's a pump salesman that calls on me that only carries these esoteric, specialty, niche pumps.  I would have called him.

Good luck,
Latexman
