The Pedrollo 4PD-0.75HP-0.55kW-230V model is a single-phase, 4-inch oil-filled electric motor designed to be installed in conjunction with Pedrollo 4SR pump hydraulics. Thanks to its NEMA standard compatibility, the motor easily integrates into submersible pumps and can be used in autonomous water supply systems for private homes, country houses, irrigation, and firefighting installations.
Design Features and Materials
Oil-filled motor, ensuring efficient cooling and lubrication of internal components. The oil is non-toxic and safe in case of accidental contact with drinking water.
AISI 316 stainless steel casing, resistant to corrosion, even in water with increased mineralization.
DUPLEX steel shaft, possessing high strength and corrosion resistance.
NEMA standard flange, guaranteeing quick installation into 4SR pump blocks without adapters.
Integrated bottom anti-corrosion protection made of zinc-aluminum alloy (cadmium-free), increases service life in aggressive environments and in the presence of stray currents.
A 2-meter power cable is included in the delivery set.
