Pedrollo VX Vortex Submersible Pumps

Product Overview

The VX series submersible pumps from Pedrollo are constructed with high-thickness stainless steel and cast iron, offering excellent resistance to abrasion and durability. They feature a VORTEX impeller, which is recommended for its reliable operation and low risk of clogging. These pumps are suitable for pumping wastewater with suspended solids, sewage, rainwater, urban wastewater, and industrial discharge. They are ideal for installations in sewers, tunnels, excavations, channels, underground parking lots, and more.

The electric motor is protected by a special three-phase thermal cutout located inside the motor, which intervenes in case of overheating or abnormal absorption.
