In Awe of the Bison Pump – Cylinder Yield

Just wanted to let you know I received the pump today. Everyone is checking it out and complimenting the quality. I knew of your pumps so I was not surprised . The rest of my crew is in awe. I cannot wait to install it for the client. The one question they have I cannot answer, and I am not sure if you can. Ok on a full pump stroke with the pump fully primed, how much water per stroke?

Thank you again for the fine product. Ray

ANSWER: Yes, Ray, we can. 3″ cylinder 20 oz/stroke, 2 1/2″ cylinder 12 oz/stroke, 2″ cylinder 8 oz/stroke, and 1 1/2″ cylinder 4 oz/stroke. Our shallow well one-piece $20 oz/stroke and our utility 10 oz/stroke.
