Title: PSI v flow
Post by: mark_roberts on May 05, 2004, 11:31:39 pm
What flow and psi do you run your truckmounts and portables at?

Is there a switch to reduce flow and psi or does the flow reduce when the psi is reduced?

Whats the average flow and psi you run at?

thanks
Mark

PS. if gallons per minute is that US or UK gallons.

Mark, There is a control for the psi usually set at between 300 and 400 psi. There is no control of vacuum on the machine, but I have a adapter which fits between the wand and hose. This has a slide which opens a hole and bleeds off some of the vacuum. I use this when cleaning rugs, so as not to have to get the customer to stand on one end, or drag them round the room. Normally you want max vacuum to extract as much moisture as poss.

thanks Dave

I ment solution flow in gallons per minute.  ie. if your pump is rated at 3 gpm do you actually use all 3 gallons or is it adjustable like the psi.

In your opinion how much more powerful is the vacuum on your Boxer compared to the Ninja.

thanks
Mark

Mark,

Most flow controls work by bleeding off some of the pump output. this has the effect of reducing both flow and pressure, although both are also effected by jetting.

The GPM figure normally refers to the US gallon, which is only four-fifths of a 'real' gallon. This applies to most pumps manufactured outside the US as the figure is more impressive.

Sorry mark, Yes it is adjustable via a flow guage calibrated 0 - 10 GPM probably American. Vacuum is a lot more than my ninja, on paper twice as powerful, in practice probably 3+. Operates 150 feet hose no problems, think it will go to 400 feet if you have that much. Can tell customers 2 hour drying times without feeling guilty.
