      Brand of small reliable submersible pumps?

      Anyone know of a manufacturer/brand of reliable small submersible pumps, say in the 300 GPH - 600 GPH range? I've had many over the years, and they all seem to break. It's rarely anything to do with motor, electrical, or impeller. It's almost always small plastic parts used to connect two pieces together. Often it is the little pieces that hold the leaf guard over the intake. In the case of the pump below, the leaf guard is a sturdy plastic screw-on type. So that part is fine. It's the little pieces that connect the covering of the impeller over the impeller. You can see that the one on the bottom is cracked, and the one just above the rubber band is broken off.

      Unfortunately, the tie wraps and rubber bands to half-way hold it together do not come as accessories with the pump.

      If using a submersible pump best to design or purchase a pump cage for it or if the intake is threaded design a extra large suction strainer. The small strainers and snap on cage require cleaning too often for long pump life.

      For the output if rigid plumbing is attached it must be supported and not put pressure on the pump housing. Use of a flex hose can isolate stress.

      If submersible pumps aren't kept clean life is greatly reduced.

      Yeah, if I am using it for more than a few hours, I put the pump in a mesh bag and then put that in a plastic cage that I make out of a couple of planter baskets.

      What kind of gph are you looking for? Laguna Max Flo pumps come with a nice sturdy cage, low wattage and a good warranty.. I’ve been running my 4200 for about 20 years now with no issues and nothing cracked.

      Doesn't matter what type. If the plumbing puts pressure on the housing cracks and breaks can develop. I've had plenty of cheap submersibles and have never cracked a pump case. Ultra cheap pumps can last many seasons if installed correctly and kept clean.

      I'm sorry folks! *Ci* your question made me realize I typed 300 W - 600 W when I meant 300 GPH - 600 GPH. Good Grief! Calling a 600 W pump small!
