The Pedrollo 4PD-3HP-2.2kW-230V model is a single-phase, oil-filled electric motor with increased power, designed for 4-inch Pedrollo 4SR pumps. This is one of the most powerful models among single-phase motors, ideally suited for users who do not have access to three-phase power. It combines reliability, safety, and outstanding performance even at great depths.
Engineering Features and Materials
✅ AISI 316 stainless steel casing – resistant to aggressive water, acidity, and mineralization.
✅ DUPLEX steel shaft – guarantees wear resistance and durability in intensive operating conditions.
✅ Oil-filled cooling system – not only provides heat dissipation but also protects the motor from overheating. The oil is safe in case of accidental contact with drinking water.
✅ Anti-corrosion protection of the lower part – made of zinc-aluminum alloy, resistant to stray currents and corrosion.
✅ NEMA standard flange – full compatibility with Pedrollo 4SR pump hydraulics.
✅ A 3.6-meter power cable – convenient for installation in deep wells.
