I've a submersible pump in my static IBC tank, fills up my 650l tank in roughly 10 mins.
Has to pump the water 45m through a 1 inch hose, its a 125l per min pump.
Gardinerpoles do them for a very respectable price....a bloody sight cheaper than the place I got mine from too
I won't name the company, but they are a major player in WFP and I feel really ripped off over it
The identical pump as Gardinerpoles sell (to look at anyway) and twice the price.
