Description
Engineering Application & Overview
The Grundfos CR, CRN, CRE, and CRNE Series vertical multi-stage centrifugal pumps are globally the most recognized high-pressure, variable-flow pumping solution for precision water supply and industrial fluid handling. Built on a vertical axis with stacked radial-flow impeller stages, they generate exceptional pressure heads in a compact footprint. The CRN variant uses all-stainless AISI 316 wetted components for corrosive fluid resistance — ideal for seawater-adjacent applications in Kepulauan Riau’s saline environment. The CRE and CRNE variants integrate Grundfos MGE variable-frequency motors for constant-pressure booster control. Applications: high-pressure booster sets for municipal and building water supply, RO membrane pre-feed pressurization, seawater desalination pre-treatment at island facilities, industrial cleaning systems, and shipboard freshwater generator feed pumps at Batam shipyards.
