I did not know until just after I posted. DAB has different products, rather than rebranding Grundfos. DAB is new to me, but they clearly are a big outfit.ill look at that grundfos pump equivalent later this afternoon. I didn't know grundfos owned dab!
Fear that the water level will drop. Unless there is a reason to the contrary, you would usually like to have the pump 20ft or more above the bottom to give room for sediment.this is an offshoot question i guess but- is there any reason a pump would be set that low(285) in practice ?
But the effort the pump exerts is overwhelmingly the lift from the water surface, and not the lift distance from the pump. The water flow resistance of the drop pipe is relatively low compared to the head due to lifting.
What do you mean by "ss"? Not stainless steel, because that would be very expensive.Ok guys - i made a serious error on the casing diameter as i am not on-site. its actually 6"ss casing! not 4" .
Yeah, that 6 inches is a big difference. The 6 inch does call for a flow inducer for better pump life and maybe some other advantages. If your pump guy is not used to doing that, search out info. This forum is a good place to search using the search box above. You could build the flow inducer yourself if the pump guy does not do that usually.
