Hi Folks!
Fresh oot o' me hospital bed,after a nasty chest infection and pneumonia at the base of me lung![as weel as an acute kidney injury!!]
Tired and very weak,but fighting it,and mighty chuffed ti find that Eggy has posted the report from the northern coalfield.
A had the dvd for a loan of from a friend a lang time ago,and have since googled it with nae success!
A worked with aal three of these lads,but especially John and Alan,real gud Marra's ti hae!
Aav nivvor seen a pump like this personally,but just past experience wi loads of different types of pump tells me that this is a single-stage centrifugal pump,definitely not a submersible one,cos the base of the pump has the suction and delivery pipe flanges clearly shown.
The suction pipe was always flexible to allow the " Strum-End" [pipe-end with a filter attached],to be lifted out of the water to be cleaned of sludge periodically.
The lifting eyes shouldn't need any explanation,given the size of the thing!,but it would have been suspended above the high water mark,on block-and-tackles,to assist maintenance,below the Sump-boards at the shaft bottom.
It's marked No 2,cos usually there would be two pumps in the sump.
Submersible pumps are self-contained sealed units,with a built-in grill inlet at the bottom of the pump body.
Check out my pit pic above,and note the small " upside-doon pail-like thingy",wi the red fire-hose coming oot the side,next ti the strata,noo that's wat we caaled a "Dalek" pump,[for obvious reasons!].
Noo when ye set that little submersible pump away,it pumped full-bore under so much pressure,that a fifteen stone bloke standing on the hose,cudn't even begin ti squash it,the hose was hard as a rock!
The waata in the pic is owa a foot deep for aboot sixty or more yards ootbye from the face,and that Dalek pump wud hae the waata doon in aboot an hoor.
Of course when we started drilling,the pump had mair work ti dae cos the windy drillers teemed waata oot like a tap running full bore.
Modern shaft bottom pumps were massive things,cos they had ti pump water vertically up a thousand-foot deep shaft,[deeper in some pits],through pipes upto a foot diameter!.......that's a hell of a lot of waata!!
Eggy,if ye cud put aal me pit pics on here,tha's one taken just as the cage disappeared doon the shaft,from bank,[surface],and ye can get an idea of the size of the pipes coming up the shaft.
Hope aav been a bit o' help,although lang-winded.....as usual!!
