adding GPM

[B.A.]

Will a Honda 13hp belt drive push a pump of 5.5 gpm or more? What i mean to say is ... can you replace a smaller pump with a larger one and keep the generator?

 

[BUNN]

If horsepower remains steady, as you increase GPM you lose the power necessary to build pressure. Yes, a 13HP engine can push 5.5GPM, but it will not be able to maintain 4,000PSI as it could with a 4GPM pump. You could put an 8GPM pump on a 13HP engine if you wanted to, you would just be limited to a lower pressure.

HP= pressure, if you want more gpm and pressure you will need more HP.

it all makes sense now...

I actually put a 5.5 gpm/3000 psi gear-drive pump on a 13 hp Honda. It delivers 5.5 gpm @ 2500 psi. Much better running a 20" surface cleaner.

What brand pump, John?
Got a link?

Yeah, good timing

I have an 11Hp GX340 honda engine with a "broken" AR pump and I'm trying to replace it, but I can live with 2500/300PSI if I can get more GPM.

If someone wants to chime in and help me out here .... I'll mail you a beer

AR makes a direct drive 5 or 5.5 gpm pump that will fit right on what you've got. With 11 hp, you can get 5 @ 2,500 or 5.5 @ 2,250. Plus, sticking with AR brand, your unloader setup should go right on regardless if it's seperate components or a bolt on. Call me for pricing if you like.

Russ, PM those prices with shipping included to 77450.
how difficult is to remove unloader and that stuff and put the new one back ?
I was hoping for something like THIS
just "plug-n-play"

 

[Russ Johnson]

Oh no. Stay away from that model. I have replaced several under warranty on John Deere washers. They're fragile. The valves are no good. You want an RKA or RKV. That's the RSV.

Does the unloader bolt to the side of the head? If so, just pull the 2 bolts and move it.

Just get a General or a CAT and be done with it...

Its a Comet. Bought on eBay from Clean Water Solutions. They are not showing any for sale at the moment, but their number is 866-897-6005. They were great to work with and I have been very pleased with the pump.

Is loaded in the van right now, ready for a small driveway tomorrow, but I'll take a look at it and see how the unloader is attached and see.
Thanks for the heads up.
What about pricing on the RKA or RKV's ?
PM that if you will.

Here is your hp formula for a gas engine. Gallons per min x PSI / 1100 = hp required for operation. As long as your hp is equal to or greater then required you are ok.

hey i am building a 3500 psi at 10 gpm

Russ I am doing a 8-10storie building. My goal is to have my pressure washer on the flat roof where there is water hook up. But my question is how high can I go before I have problems. I heard what can happen is the cerimac pistons might crack if I run it from the ground. I will be renting a 120 lift.

 

[Russ Johnson]

The pistons will only crack if you leave the machine in bypass for a long time.

What are your plans?

one pump system or two pumps combined at those specs?

I aquired a 20 hp Honda yesterday.. Any suggestions for running a pump and running it thru my whitco burner... ???? What about Gpm to heat ratio for a burner ...
