Some specs by asetek:
12V DC Standard Pump & Reservoir unit.
Power consumption: 7W
Qmax: 900 l/hm
Hmax: 150 cm
It seems to me like a miracle.
It is a 2 pole stator with aquarium regular impeller.
They claim to get 15 L/min (900 L/h) with 7 W at such motor design...
... i can not believe on that specs...
