Pearl 4MWP 30C363 4-Inch Submersible Well Motor (3 HP, 230V, 3-Phase, 3-Wire)

The Pearl 4MWP 30C363 is a 3 HP, 230V, three-phase, 3-wire, 4-inch water-cooled submersible well motor designed for deep-well pumping and replacement applications. The two-pole asynchronous motor features AISI 304 stainless steel wetted components and a sealed stainless steel stator housing. A water-glycol mixture provides cooling and lubrication.

A 3-wire, two-pole asynchronous motor featuring durable AISI 304 stainless steel construction for components in contact with water. A water-glycol mixture provides cooling and lubrication, while the sealed stainless steel stator housing ensures reliable operation. Compatible with variable frequency drives (30–60 Hz), with capacitor and manual-reset overload protection provided through a separately available control box.

** Overload protection must be provided by user for the three-phase version.
