Proline HP300 Pump basically new , 5.5 HP Engine & T80 Compressor. The pump & engine have only been used for half an hour for a test run on a 4" dredge , plenty of suc & air was happy with the performance however my homemade key that held the compressor pulley in place came out I had dredging in the hills to do the next day so grabbed another unit so this gear listed has sat in the garage for the last year I don't really need it as I have 2 others so out it go,s.The pulley is in the garage somewhere if I find it itl be included in the auction.
