The Shark grinder pump series now includes 1- and 1.5-hp models 818 and 819, joining the 2-hp model 820 in the pump family. The dual-bladed angled cutter’s scissor-like action shreds difficult wastewater materials to a 1/8-in. 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. All the company’s pumps are 100% factory tested.
