Clean It Up

I currently have a 150 psi ninja and am happy with the vac performance but was thinking a pump upgrade will increase my productivity. I have sourced a 500psi pump from woodbridge. The machine already has a pressure regulator valve and bypass and the existing hoses appear to be the correct pressure. Is there any thing I haven't thought of? or does anyone have any advice?
Thanks

You haven't thought of only having 2 standard vacs with a 500psi pump. You may not get the best results as you would be leaving the carpet wetter.
Ashby's do there own 400 pump so I would speak to them.
-
why would using the 500psi pump at 250 - 350psi with two vacuum motors leave the carpet any wetter than any other twin vac with this pump ie:
The ninja (which uses the same pump but restricted)
The powerflite PFX1085
The powerflite PFX1350
The mytee speedster
The Kleenrite edge
The airflex pro
etc etc etc...... ???

Is there enough space for the pump in there?
You might need a cooling fan or ports depending on the set up of your machine.
-
There is just enough room but I think im going to have to re-route some bits and pieces, the exhaust at present takes up quite a lot of room. It does have two cooling fans one sucking air in one blowing it out.

How is having a bigger pump going to increase productivity?
If you lose the balance between what is being put down and what is being recovered, surely your going to spend more time making extra drying passes.
I'd leave well alone.

That's exactly the point I was trying to make. Although Simon put it much better.

Higher pressure doesn't allways equate to higher flow rate so you aren't actually putting more solution out its just hitting the fibres harder.
You could even have a bigger pump and use smaller jets.
Even if you are putting out more solution strangley you can often recover more as well as the additional fluid creates more lift at the wand.
You often find this if you are flooding carpets like Flotex or glue down Polyprop in nursing homes to deal with urine. In extreme cases I used to mix up urine neutraliser in a bucket and pour it on to the affected area. This helped the product contact all of the urine including that which had gone into the concrete slab. Then on extracting I found that this area was often drier than the areas just cleaned normally.
-
The only way of hitting the carpet harder and not increasing the amount of water put down is to reduce the jet size.
The balance is about maintaining the air/ water mix inside the vac hose so that the machine can maintain optimal performance. Increase the amount of water in that mix and you lose performance.

John do you have a recommendation for jet size in a 2 jet 12 inch wand for use with higher pressures?
-
I'd use 1.5's

Thanks John
For ones who have gone from a 135/150psi pump machine up to a 500psi machine do you notice much in the way of improved productivity or is there not much in it?

150 UPTO 500PSI,
Few things here. Autofill would be good, as your shift through the water quicker. Also you can be a little more blase with pre spraying on the higher psi, as you will blast dirt away, less passes needed, but extra drying passes.
But the 150 psi still has a place, just need to cover prep stage thoroughly and you will still get good results
May depend on what work your doing day to day.
80/20 dom/comm 150 is ok, just may need a rotary scrubber for commercial stuff to give extra clean
50/50 you will need higher psi imo, may still need to buff off low profile after for best results

I have auto fill and empty so no probs there, and a rotary.
I do a range of different carpets and generally get good results as I always try to prep well. Most important part imo.

I used to own a 400 psi Ninja, but when i purchased my 500 psi Scorpion, I noticed a massive difference, there must be a much bigger flow rate with the 500 psi pump, Also the electric motor on the 500 psi pump was much bigger
