Try using some skimmer socks or other some such pre-filter to catch those needles before they get to the pump. I don't know of any pump that would handle the situation better than another.

Note: I am NOT endorsing this retailer as I have never dealt with them. They just happened to be near the top on my google search.

Hope this helps.
