Engine Pedrollo 4PD-10HP-7,5kW-400V

The Pedrollo 4PD-10HP-7.5kW-400V represents the pinnacle of engineering solutions in the Pedrollo 4PD submersible motor line. Designed for operation with Pedrollo 4SR pumps at depths of up to 200 meters, this motor is capable of handling the most intensive and resource-demanding water supply tasks: from large agricultural areas and industrial facilities to distribution pumping stations operating 24/7.

Superior Construction and Materials

✅ AISI 316 stainless steel casing — resistant to corrosion, chemically aggressive substances, and the impact of solid mineral particles. 

✅ DUPLEX steel shaft — designed for high torsional and axial loads, ensuring durability without loss of performance. 

✅ Oil-filled cooling system — protects against overheating, reduces wear, and is non-toxic upon contact with drinking water. 

✅ Anti-corrosion bottom protection — made of cadmium-free zinc-aluminum alloy, effectively neutralizing stray currents and high water mineralization. 

✅ Standard NEMA mounting flange — fast and precise connection to Pedrollo 4SR hydraulics. 

✅ Power via a 3.6-meter cable — included in the set, designed for operation at depths up to 200 meters.
