MEKX series 60Hz

Summary

Product Identification

This document describes multistage electric pumps in microcasted stainless steel, specifically the MEKX, MEKRX, and MEKVX series, designed for 60Hz operation.

These are close-coupled monobloc multistage electric pumps widely useful in water supply and boosting technological plants for irrigation, residential, and industrial applications. They are engineered with advanced technical solutions for efficient and reliable pumping of a wide variety of liquids.
