Grundfos CR Series

The Grundfos CR Series Vertical Multistage Centrifugal Pump offers an in-line solution with suction and discharge ports in the same horizontal plane, for installation in horizontal one-pipe systems. Base and pump head material types of the CR Series include cast iron and stainless steel (CR), stainless steel (CRI / CRN), and titanium (CRT). Wetted parts of these pumps are of stainless steel construction. The CR Series is suited for chemical and potable water pumping solutions, meeting specifications across industries including commercial heating, air conditioning, and water pressure boosting.

The CR and CRI variants are designed for non-corrosive liquids, for applications including liquid transfer, circulation and/or pressure boosting of clean water.

The CRN variants are designed for industrial liquids, for systems where every part of the pump requires high-grade stainless steel construction.

The CRT variants are designed for saline or chloride-containing liquids, such as seawater, hypochlorites, and other oxidizing agents.

Each of these subseries is available with an integrated frequency converter, to support variable flow at constant pressures. Extensive pump sizes offer a range of flow rates and pressure ratings to meet specific application requirements. CR Series pumps are standard-issued with heavy-duty, 2-pole NEMA C-face WEG motors. 0.25 to 20hp WEG motors are constructed of rolled steel, with 25 to 300hp variants featuring a cast iron frame.
