Pump Engine setup

Mr. HotWaterWizard

I'm a big fan. Several years ago I came across some of your burner info and some diagrams that really helped me out.

Questions - I think your just the guy who can answer
If your putting out 4 gal at 3000 psi and bypassing 4 gal, is the engine working to put out 8 gal at 3000psi ?

I'm planning to run a 12 gal pump between 6 and 10 gal with a 28 hp engine and a k1 (specs say 2-10 gal) unloader and I want to adjust the rpms up or down to match what I need. Do you think this is a workable plan and where would you run the engine? I'm trying to consider fuel, engine wear, pump wear.

Here's the hp/torque for the engine

Thanks
 
Sory for the Delay on my response.

The pump is positive displacement. it will put out it's maximum flow at all times.
The nozzle size determines the PSI and the RPM determines the GPM
If you run the pump slower than the rated RPM the GPM output will go down.

Nice talking to you. My question is mostly curiosity. If your spraying say 8gpm but only using 6 at the nozzle - bypassing 2 - do you 'pay the price' at the pump for 8? Does the pump have to produce all 8 at full pressure?
