” I.D. will result in decreased pump performance. When
pumping dairy or piggery slurry, no inlet strainer should be tted to the end of the suction hose as this may
easily be blocked.
The pump is capable of pumping up to 3/4” dia. solids in suspension, however pumping stones or hard
solids of any size for extended periods will shorten the pump’s life. A coarse screen should be installed
at the entrance to the collection pit to prevent large items including rocks, sticks and some straw from
entering.
