Aqua Evolution 12000 sequence pump I have two of these pumps for sale; see my ‘other items’. I have now replaced them with the new models. If you are bidding, you are bidding for one pump only. The pumps have given me good service over the last 4 years keeping my pool filtered. They both work fine, but would be better if serviced as they sometimes need a ‘flick’ of the impeller to restart them; consequently I leave them switched on 24/7. I’m told that they need new capacitors which cost about £5..(I can’t find the right size). These pumps are gravity fed and need to be installed below the water level! Inlet 2” outlet 1 ½” Max head 2.5 Mt 12,000 Lt pr hour (2,640 Gall).
