Pedrollo Engine 4PD-4HP-3kW-400V

The Pedrollo 4PD-4HP-3kW-400V is a three-phase, oil-filled submersible electric motor with a power of 3.0 kW, designed to be paired with Pedrollo 4SR pump hydraulic modules. Thanks to its resistance to high loads, aggressive environments, and prolonged continuous operation, this motor is ideal for professional water supply systems in private, farm, and industrial settings.

Design Features and Materials

✅ AISI 316 stainless steel – used for the casing and main external elements of the motor, ensuring high corrosion resistance. 

✅ DUPLEX steel shaft – resistant to axial loads, not subject to deformation even under intensive operation. 

✅ Oil bath – reliable cooling and lubrication of internal components; the oil is safe for contact with drinking water. 

✅ Anti-corrosion bottom protection – made of cadmium-free Zn-Al alloy, designed to protect against stray currents and aggressive impurities. 

✅ NEMA standard flange – guarantees perfect compatibility with Pedrollo 4SR hydraulics and quick installation. 

✅ Power cable with a length of 3.6 meters – included in the package.
