Protect the impeller and mechanism from what?surnimensis;4185252; said:I have never built a sump or closed loop system filter. But it seems a much better idea to have the filter below the pump just to protect the empellor and mechanisem. Sorry just a thought!
I think he was worrying about debris/sand/gravel from the tank hitting the pumps, but if you have debris traps before them, they'll be fine.nolapete;4185385; said:Protect the impeller and mechanism from what?
yup thats what i was thinking, if any foregin objects get to the pump like sand, they would have a wearing effect. But i guess youve already thought of that. if you experience flow problems and drill holes in yr pump protectors you may experience trouble that way.Conner;4185519; said:I think he was worrying about debris/sand/gravel from the tank hitting the pumps, but if you have debris traps before them, they'll be fine.
