Thanks Tommy. I'm interested in the injector type that attaches at the wand end. My nozzles are the standard quick connect type used by most professional and higher end consumer equipment. The unit develops 2,500 psi.
I want to wash mechanical parts using a mixture of water and some abrasive material such as baking soda, so keeping the media out of the pump is essential.
I've tried using air soda blasting equipment, but it tends to clog often due to humidity and other factors plus it's somewhat difficult to regulate the amount of media used. Sand blasting tends to damage the surface of the parts too much.1. Does the device in link #2 above pull an abrasive solution from a container while the nozzle is operating at full pressure, or is a soap nozzle required?
2. What other abrasive materials can be used in this type of system?
3. Can you recommend a different and better alternative?
4. Will using 150 degree water improve the cleaning rate?
It is made to pull from the container just like a sand blaster using the water flow for the suction instead of air like a sand blaster.
Now, it is hard to say how well it will pull if the solution is too high in solids concentration.
That part would have to involve some trial and error to get the correct consistency as most pressure washers are used for liquid mediums and not much testing has been done in that area to my knowledge.

The higher temperature would certainly help with the cleaning process.
The only thing to look at when using a higher temp, is watching the pump for any problems.
Don't know if thee is any issues with your unit or not, the manual would state if temperature is a problem, but I would say it is not an issue at 150 degrees or so.
Stay aways from anything higher as it could create some flashing at the nozzle.
Thank you Tommy. You always have very clear answers.
