After spending $7500 on a solar mono pump that lasted for 6 years with 2 rotor and stator replacements at $1100 a set. I was questioning the viability of submersible pumps in a river that floods. In the end the pump and motor were still ok but the sun buddy controller died and they wanted another $1600 to replace it.
Decided to try this jobby. Admittedly has 10% the flow of the previous pump(250w), but so easy to install, ran perfectly until the pump got buried in sand in another flood, but super easy to replace stator and rotor and get it going again. Very good value for money.
