Pedrollo Engine 4PD-1HP-0.75kW-230V

The Pedrollo 4PD-1HP-0.75kW-230V model is a single-phase, oil-filled electric motor for 4-inch submersible pumps, designed for domestic and light industrial applications. Thanks to its NEMA standard compatibility and high reliability, it is used for Pedrollo 4SR deep-well pumps, ensuring stable water supply at depths up to 200 meters.

Design and Key Components

✅ Sealed AISI 316 stainless steel casing ensures corrosion resistance and extends the motor's service life when in contact with mineralized or slightly aggressive water. 

✅ DUPLEX steel shaft — one of the strongest and most wear-resistant materials, especially during continuous operation. 

✅ Oil cooling — circulation of non-toxic oil ensures smooth and efficient operation, reducing the risk of overheating. 

✅ Anti-corrosion protection for the lower part of the motor — made of a cadmium-free zinc-aluminum alloy, suitable for use with drinking water. 

✅ A 2-meter power cable — included in the set, ready for connection and installation. 

✅ NEMA standard flange — guarantees compatibility with most pump modules.
