Pedrollo Pumps Series VXC 3" manual submersible, 3" solid handling, sewage pumps from 1 HP to 2 HP in single and three phase. Used for storm water protection, underground car parking garages, car washing areas, wastewater and sewage disposal. The vortex impeller spins in an area of the volute that is completely out of the liquid flow path. The spinning creates a vortex similar to that found in a tornado. Whatever goes into the pump suction will be pumped out as long as the solids are smaller than the discharge connection.
