PTO rpm/ BH pump rpm?

[YukonKing]

hi guys,

I am trying to figure the GPM of my LW-6 backhoe pump. It is marked 10ml per revolution now if I knew the rpm of the shaft I could do the math. Assuming the PTO was at 540rpm what would the bh pump be turning at and at 1000rpm respectively? Or if anyone knows that would be great.

Thanks,

YukonKing

If you are using the factory supplied pump (mounts with four bolts above the splined PTO shaft), it turns at engine speed. It's rated output @ 2,000 r/m is ~6.75 GPM.
