Thank you for visiting Water Pumps Direct. The Honda WSP100AA is probably one of the best electric submersible pumps that you can buy. Since you are installing outdoors and there is the possibility of some small debris getting into the pump, the Honda or TSURUMI Trash pumps would be a good option for you. The main difference in the 2 brands are that the Honda pumps have a higher pumping capacity and an open bottom to the pump impeller and the Tsurumi pumps typically max out at 60 GPM and offers a bit more protection from larger debris getting into the pump inlet or impeller.
If you have additional questions, pleas don't hesitate to contact me.
