Pedrollo Engine 4PD-1.5HP-1.1kW-400V

The Pedrollo 4PD-1.5HP-1.1kW-400V model is a three-phase, oil-filled electric motor designed to be assembled with Pedrollo 4SR pump hydraulics (4" diameter). It is suitable for use in deep-well water supply systems for private homes, industrial facilities, farms, and greenhouses. Thanks to its stable three-phase power supply and oil cooling, the motor demonstrates high efficiency and a long service life even during continuous operation.

Design Features and Engineering Solutions

✅ Sealed AISI 316 stainless steel casing – resistant to aggressive environments and the effects of stray currents. 

✅ Oil cooling – internal circulation of non-toxic oil reliably protects the motor from overheating, ensures smooth operation, and a long lifespan. 

✅ High-strength DUPLEX steel shaft – stable operation under increased loads, wear resistance during prolonged use. 

✅ NEMA standard flange – ensures precise fitting into Pedrollo 4SR pumps, reducing installation time. 

✅ Anti-corrosion bottom protection made of a safe zinc-aluminum alloy, recommended for contact with drinking water. 

✅ A 2-meter cable is included – ready for connection.
