4″ Deep Well Submersible Pump with Technopolymer Discharge – Model 4PWT05G

The 4PWT05G is a compact 4-inch deep well submersible pump with technopolymer discharge, designed by Pearl for low‑flow, high‑head applications in residential, agricultural, municipal, and industrial water systems.

Engineered for deep well potable water supply, this model delivers reliable pressure and consistent flow at low capacities, making it ideal for pressure boosting, irrigation, livestock watering, and fountain applications. Its hydraulic design allows efficient operation in installations requiring significant vertical lift with controlled flow rates.

The pump features a corrosion‑resistant technopolymer (Noryl®) discharge with an integrated check valve, ensuring reduced maintenance and long service life. The floating impeller system optimizes hydraulic performance while improving durability when handling water with light sand content. Built for continuous‑duty operation, the 4PWT05G provides dependable, long‑term performance in demanding deep well environments.

A NEMA standard motor adapter ensures compatibility with industry‑standard submersible motors, offering flexibility for new installations and replacement projects.
