Pump for a 10x5 overflow ?

[LivinLOS]

Currently have a very budget 8 x 4 fiber pool that was pumped by a .75hp chinese LX pump which I always felt was low flow but wasnt sure if it was just old / weak or not enough power spec. Pump has died and I cant get an impeller anywhere (even tho there are companies selling the pumps.. No parts !! and no reply from china HQ after many attempts.. Usual bad budget choice) so new pump time. Currently powering it with the spa pump which is noisy and higher hp. 

Next year the whole lot is being pulled out and I hope to fit in a +- 10x5 overflow concrete pool and redo to a salt system and a few nicer features. None of it is properly specced out yet but assume a 1.5 deep end and a 1m shallow end, steps and features I am guessing 60 - 70 cube volume ?? 

 

Makes sense to buy a pump now that will easily operate that kind of volume and healthy overflow. What hp / flow rate should I consider ? 

Price is secondary (but not irrelevant) to lifespan, parts availability, efficiency.. So basically suggestions on a 'decent' brand without looking for the greatest. Theres stuff on lazada for 5k but I assume it will be chinesium junk.. Emaux seem well supported ?? 

Any advice or things I am unaware of ??

Emaux is the VW of the pump world and quality depends on which factory it came out of. Pretty much all pumps these days are of Chinese origin, whole or in part and are just branded. Once a pump is old it's best to get a new one rather than try to repair it unless you are low on loot.  A quality 1 hp would do the job you require with around approx 350 - 400 litre a minite flow rate depending on "head" distance from pump room.  I supply.
