I think Enkamat was the specific type, I tried several other things in lieu of this including a red dish "scrubby" for pots and pans, gutterguard, some "critter guard" from work (like a 0.5mm mesh) and another type of enkamat. All of them sucked. The PF4 is definitely the one to get. I think there are a couple of people on here selling extra, maybe do a search for "enkamat"
As for the pump, I have no idea whether it actually wears on it or not. My pump has been running for probably close to 2 years with the enkamat on it (3-4 layers) without a problem. Only thing is that sometimes it wouldn't start up after a power outage, make sure you trim the enkamat well so it doesn't touch the sides of the impeller housing.
