What happens if I put a TS2021 pump , with the pulleys off a ts1511 pump .. and run it with a 13hp motor>> Will I get more GPM?? More Pressure ??? or will it just pump 3500 @4 gpm like the ts1511.. ??? I can buy the ts2021 cheaper thean the ts1511 thaqts why I am asking...

Just kidding around, I don't know the answer, sorry John, I just couldn't resist.

Thanks for all your informative posts on the board. And again I apologize for this waste of time.
 
The pulleys are standard sizes. Typically, you will approach the 3000 PSI at around 4.25 GPM, That is the Scott's new math of calculation. It is very possible that you will get more GPM than that, though. The 2021 is rated at the same GPM as the 1511. You can use a smaller pulley on it to get more GPM, at the cost of some pressure.
 
Thanks Scott... I just wanted to make sure I wouldn't do any damage to the new Honda GX390 that I just bought... I am saving all my old stuff as spare parts since it still works, the motor , the pump etc... Never Hurts to have backup stuff when you work at night , after all the pressure washer parts sales people are asleep.. I have always said that when I get to old to steam clean I am going to open a 24 hour , roadside pressure washer parts and service business...
 
It will work just fine you just do not have the horsepower to get the full performance of the TS2021. To figure out what you can acheive take GPM x PSI /1100 = HP required.

Such as...
2500x5.6/1100=12.72 hp (will work)
or
3500 x 4.2 / 1100= 13.36 hp (will not work)
or Scotts calc.
3000x4.25/1100= 11.59 hp (will work)
 
The 2021 puts out 1.4 times as much water, gpm, at any given speed.
 
I would be more concerned with keeping the GPM close to what you had before, so that your burner can keep the water temp similar to what you're used to, knowing what the machine is used for.
 
or even sacrifice the gpm's and get a greater heat rise may even help. I don't know much about cleaning hoods but I do know that the hotter the water gets the easier the grease melts off of the grease cans used to carry grease out to the infamous black boxes
