Grundfos inline multi-stage pumps are vertical centrifugal pumps featuring multiple impellers stacked within a single casing. They provide high-pressure capabilities suitable for applications that require an elevated water supply. These pumps are designed with suction and discharge ports at the same level and are commonly used in water supply, water treatment, and industrial solutions, including those handling aggressive liquids.
The CR pump is constructed from rigid cast iron, with all wetted parts made of AISI 304 grade stainless steel. It offers exceptional efficiency along with high flow and pressure capacities, making it ideal for demanding applications such as liquid transfer, circulation, and pressure boosting of both cold and hot water, as well as in aqua-farming and field irrigation.
The CRE is a versatile pump made from AISI 304 grade stainless steel and cast iron for enhanced durability. This range is available in various flow and pressure sizes suitable for applications such as water supply, washing, water treatment, boiler feed, chemical processing, temperature control, and mining. The CRE pumps feature a variable-speed drive (VSD), allowing them to continuously adjust performance to match current conditions and achieve the desired pressure, temperature, or flow.
The Grundfos CRI and CRIE inline, multi-stage centrifugal pumps are designed for liquid transfer, circulation systems, and pressure boosting of both cold and hot water, as well as slightly aggressive liquids. The CRIE pumps are equipped with a variable-speed drive and an efficient motor, offering optimal efficiency and control.

The CRN range offers a diverse selection of flow and pressure sizes. Constructed from high-grade AISI 316 stainless steel, the CRN is ideal for applications such as ultra-filtration, reverse osmosis, cooling lubricants for machine tools, distillation systems, swimming pools, oils, alcohols, acids, alkalis, as well as process water systems that handle a variety of challenging liquids. ATEX-approved CRN pumps are also available.
The CRNE pump is entirely constructed from high-grade AISI 316 stainless steel, making it a high-efficiency inline multi-stage pump equipped with a built-in variable-speed drive suitable for handling industrial liquids. It is particularly effective in applications where all components in contact with the liquid must be made from high-grade stainless steel, especially for dangerous and aggressive liquids.
The single-pump CRNE-HS and two-pump CRN-SF are inline, multi-stage pump systems designed to withstand the extreme conditions of high-pressure applications. They are suitable for use in washing systems, water treatment facilities, industrial plants, boiler feeding systems, filtration, and reverse osmosis. The single-pump CRNE-HS can handle flow rates up to 5 m³/h, while the CRN-SF models are utilised for higher flow rates.
