We have been researching the Impact of Truckmount & Portable pump systems.
In talking with Spraying Systems engineers, the importance of GPM over pressure has been clarified.
Impact is more dependent on GPM than PSI.
If you double GPM. the Impact goes up 100%.
If you double the PSI the Impact goes up 41%
We have noticed this dramatically on rotary jet Tile & Grout cleaning.
The top rated T&G equipment (Turbo Hybrid) has two 0502 jets (total of #4).
On a TM, changing to two 0503 Jets will increase the impact to 150%.
Try this out on a tough T&G cleaning job.
We also like a minimum of #8 or #10 in total jet size on 14" wands.
Pressure hose diameter does become a factor with long hose runs.
