The ID tag is damaged. Can anyone tell me what it is?
The pump is a Barnes/Haldex 11 gpm 2-stage pump which is sold under many different brand names.
If I swap this 11gpm pump out for a 16pm pump how much time will I gain?
Not enough to justify the expense.
Some of the 16gpm's are in the 9 second cycle time range.
When changing pumps you have to be sure the engine has the hp. to operate the pump. A 11gpm 2-stage pump requires a 5.5 hp. engine min.. A 16 gpm 2-stage pump requires a 8 hp. engine min.
I just installed an 11hp honda. Originally had a 10 hp B&S. Honda seems to work less.
If you make your splitter too fast you wont have time for refreshments while splitting.
Attached is a chart with diamensions that show the difference between 11 and 16 gpm pumps. Haldex/ Barnes is now Concentrics.
Need to know your cylinder size. (Bore x stroke). 16 gpm pumps aren't bad $$ wise. 22 gpm and up is where the money is. I would be looking to upsize with that engine on there too. 16 GPM would be a breeze on that Honda.
