Description
Engineering Application & Overview
The Grundfos CM and CME Series are compact, horizontal multi-stage centrifugal pumps built for high-pressure, low-to-medium flow applications where installation footprint is constrained. The stainless steel hydraulic chambers and impellers deliver exceptional resistance to corrosion and wear in clean water, mildly aggressive chemicals, and low-viscosity fluids. The CME variant integrates a Grundfos MGE frequency-converter motor, enabling variable-speed pressure control for energy savings up to 50% compared to fixed-speed alternatives — a critical cost advantage for continuous-duty installations in Batam’s 24/7 manufacturing environment. Applications: high-pressure booster units for industrial water supply, reverse osmosis pre-feed pressurization, fire suppression system charging, chemical dosing pre-pressure, and cooling water supply on vessels serviced at Kepulauan Riau shipyards.
