Aqua Medic OR2500

[NELSON76]

I just received an ocean runner OR2500 pump, I wanted to use it in freshwater as a return for a sump project but when I received the pump it came with a mesh impeller which is useless in freshwater, I've searched online for hours looking for one,My only option for getting it in the US is from Aqua Medic but they haven't gotten back to me. Does anyone who has this pump ever replaced the impeller? If so please let me know where. Thanks
