Hanson PTO water pump info needed

[BTackett]

I have a Hanson PTO water pump and trying to find out the GPM flow of it. I want to use is with a 55 gallon drum to keep water on my pumpkins as it is dry as a bone here in E Tn. It has 7/8" threaded in/out holes and I want to put a regular 5/8 garden hose on it with a faucet on the barrell and a fire hose type head on the other end.

Any ideas on what GPM these small pumps were?
