Saw this with interest. I've posted a thread here with a problem I need to solve.
We have a Blakes Hyrdram on the farm which works well most of the year but in dry times over the summer there isn't sufficient water supply to operate. What minimum water supply will the Pappa Pump operate with and how much will it pump? We have a head of 40m from the ram pump to the reservoir and distance of just under 600m. 32mm pipe between the two. Reservoir holds 14,000litres with additional 20,000 tank in main farm yard.
