The Shark grinder pump series will now include 1.0 and 1.5 HP models 818 and 819, joining the popular 2.0 HP model 820 pump family. Its dual bladed angled cutter features scissor-like action that shreds difficult wastewater materials to a 1/8-inch particle size. This improved cutter system delivers more torque per blade, lowering amp spikes and extending pump service life. All pumps are available in either automatic or non-automatic models. Pumps are 100 percent factory tested. Zoeller Company.
