Pump question

Hey Mark, pump question for you. With the machine I have been having my problem with i have a question. It has a general TSF 2221 pump on it and a 24 hp honda hot water with 120v burner and is set up for 6 gpm at 3500psi. My question is can I make it a 8 gpm? How much would I have to change? How much pressure would I loose? I use it mostly for flatwork.

Chad,

With your altitude in Goldsboro (34' above sea level) you should be able to run 8 gpm @ 3000 PSI.You will probably sacrifice temperature at 8 GPM but the pump and engine will handle 8 GPM @ 3000 PSI.:eek:
Volume is king.

Your pump will produce 8 GPM at 1365 RPM, or 8.5 GPM at 1450 RPM. Divide RPM by GPM, then multiply by desired GPM. [whatup]
See attached specification sheet on the General pump 66 series TSF pumps.

I can post some info later about sizing pulleys / sheaves, time permitting.:) I believe a search of this board for sizing pulleys, or pump rpm will find an old thread with that information.

Ok Mark I searched the old thread, and I'm still confused. I have a 8.75 pulley on my pump now so do I need to go smaller on the pump? Will I have to change my fuel nozzle also?
