We are replacing our dirty water collection pit that takes the wash-out water from the milking parlour and tankhouse. This is currently a settling tank linked to a pit with a submersible pump that pumps the dirty water/effluent through into the slurry system about 15m away and total head height about 7m through a fixed 2" plastic pipe.
Years ago, this was a 3 phase 415v pump, no idea on make or model, it was way over-specced to push the dirty water into a field irrigation system. The irrigation was done away with, and when the pump failed, it was replaced by a 240v single phase pump - no idea on current model, i think it's something like a Clarke HSE300A with a float switch. Bought last-minute from machine mart about 10 years ago. This has proved very troublesome over the years with solids blocking the impeller, sometimes won't start up, etc.
Now we are rebuilding the tank, we're going to skip the settling tank and go straight for a single pit with submersible in the bottom.
I want to replace it with something more beefy, budgeting around £600 to replace it, and can run single or three phase to it (will need a new control board anyways). It also wants a float switch, level control or dry-run protection of some sort.
Anyone got any recommendations or models to go for/things to avoid? At the moment I'm favouring 3 phase pumps just because of the easier/more reliable starting.
