“Better”, but no cigar yet. After the brass liner was installed, the pump will now take
suction at normal operating level above water, but only at high speed on the drill.
The drill tops out at 2500 rpms. Not sure what “Start” position rpms would be on this
motor, but presume less than 1000 rpms.
There is a wear circle in the top plate and bottom of the liner, the top being worse,
where the center hub of the impeller rides. Note at high speed operation on my video, water
blows out the hole on the top plate where the driveshaft goes thru. Not sure
what’s happening on the bottom side. Is this indicative of my poor pump performance?
I could make a new top plate, out of brass, if it’s worth my effort???
I don’t think the bolt holes line up if I turn the top plate over, but will re-check.
Any other ideas or thoughts welcomed.
BTW, the driveshaft has two flats on top of the driveshaft to drive the impellers,
but there’s also two flats towards the bottom of the driveshaft. Was the same shaft
used on other models with the pump down low?
I don’t think there’s a way to mount the pump down low though on this Bailer model.
Prepare to be boarded!
