7" Submersible Motor - Pearl 7MRCP

Model: 7MRCP – 7" Rewindable Submersible Motor (up to 75 HP)

The 7MRCP submersible motor is a 7‑inch rewindable, asynchronous, two‑pole submersible motor designed for high performance and long service life in demanding water well and pumping applications. Built using a combination of cast iron and AISI 304 stainless steel, the 7MRCP motor delivers excellent durability, corrosion resistance, and mechanical strength.

Available in ratings up to 75 HP, the 7MRCP submersible motor is engineered for high efficiency, helping reduce operating costs while maximizing pump performance. Its water‑cooled design ensures effective heat dissipation and reliable operation in continuous‑duty applications.

The motor features a NEMA‑standard mounting flange, a stainless steel shaft, and is fully rewindable, allowing extended service life and easier maintenance. Optional materials such as AISI 316, Duplex stainless steel, or bronze are available for high‑corrosion environments.

Designed for modern pumping systems, PEARL MOTORS 7MRCP models are VFD‑compatible, supporting operation with variable frequency drives from 30 Hz to 60 Hz, and can also be operated using a soft starter. The motor supports both clockwise (CW) and counter‑clockwise (CCW) rotation for flexible system integration.
