Recommendations for a borehole pump please

[ProDave]

Bit of an odd one, helping out a neighbour.

 

His borehole pump failed, he needs a new one quickly.  But it is not as simple as it seems.  He failed to get the old one out, he even set up a tripod and a winch and all that succeeded in doing was breaking the shackle holding the wire to the pump.  So the old pump is still down the borehole and there it will stay.  but it means I have no idea what pump was there before and anything about it's rating.

 

He thinks it is an 8 inch borehole liner but he is not sure.  He thinks it is about 80 feet deep but the water level is a lot less deep that that.

 

So erring on the side of caution I am tempted to spec a smaller pump, perhaps just 4"  it will be going down with a new lifting cable and a new length of mdpe pipe.

 

So any recommendations, not too expensive but available reasonably quickly?

Tell him to call, GRC Aquatech, they are in Aberdeenshire, but come out your direction also I believe.

So what I am finding, is you can buy a borehole pump from £200 upwards (when you ignore the toy ones) but everything I am seeing says maximum depth 20 metres and they typically come with 22m of cable.  He is adamant his borehole is 80 feet which is 25 metres.  I guess as the old pump is still at the bottom and he is sure the water is a lot higher up, that will be okay to buy one of those and only lower it 20 metres down the well?

 

This is the one that has caught my eye so far.  Thoughts please?

I have been to look at the job this morning.  I find the borehole liner appears to be 4" mdpe so a 4" borehole pump would be a near piston fit and I suspect that is what is there and it has jammed.  So I think I am now looking for a 3" pump.

 

Previous (now stuck) pump is 25 metres down (measuring pipe that came out having pulled out of the connector) and water level is about 10 metres down.  So any of the "20 metres immersion" pumps will do the the cable might need extending.  From the well head it needs to pump up to a holding tank in the loft of the house so another perhaps 15 metres so needs to be a pump that will pump up more than 40 metres.

 

Any recommendations?

 

This would do I think, but it's not in stock  https://www.waterpump.co.uk/borehole-pump-aj4-plus-5500-litres-per-hour

 

Or what about this one, supplied with a 40M cable and will pump over 100 m head and in stock.  https://www.pozzani.co.uk/Pozzani/3-borehole-pump-ssscrew-0-75kw-220v-40m-cable.html
