Finally found the ‘sweet’ spot on our ‘new’ tier 2 (230h Ritchie bros. Nisku) Cornell pump. Kubota V3600 85hp.
Feeding with a 4” Tsurumi portable pump at the big river (Quesnel). So as to save disturbance & future reclamation.
The pump is doing a 150’ head lift (around 800’ of 175psi layflat ‘black dragon’ hose layed out)
This setup is yielding around 450gpm at plant.
1850rpm, 125-130 psi at pump. Had to gently ‘release’ air from volute in order to achieve steady 125psi pressure. Also
using some 30’ sections of Goodyear ‘petroleum’ hose in critical areas. These were used for pumping canola oil in the port of Vancouver!
Was worried impeller
could have been damaged in oil patch use…engine paint etc did suggest nearly new.
Pleased as is doing required lift without excessive strain. BEP is 350’ @ 800gpm. We have a significant amount of frictional loss due to some lengths of 3” layflat.
