Pearl 4MWP 20C163 4-Inch Submersible Well Motor (2 HP, 230V, Single Phase, 3-Wire)

The Pearl 4MWP 20C163 is a 2 HP, 4-inch submersible well pump motor designed for well-water pumping applications. This single-phase motor operates at 230V with a 3-wire configuration. It has a listed maximum amperage of 11.8 amps and a catalog weight of 29 lb.

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.

Specifications:

FEATURES:

• All PEARL motors are provided with a removable cable connector. This solution allows fast assembly/disassembly of the pump end and makes easier maintenance operations.
• Kingsbury type thrust bearing unit consisting of tilting pads made of highly-resistant stainless steel and machined using spherical lapping process; this machining guarantees high reliability and high resistance to axial load to this strategic component.
• Die cast Aluminum rotor with shaft end made of Stainless Steel AISI 431.
• Encapsulated stator with outer casing made of Stainless Steel AISI 304. The stator has 24 slots for better operation and higher efficiency. The winding made of class H double insulated copper wire.

Replacement Considerations:

For a replacement, verify motor horsepower, voltage, wire count, dimensions, shaft/coupling compatibility, and required control components before ordering. Three-wire systems typically require a correctly matched external control box; confirm compatibility.
