grundfos industry Customised Solutions

Welcome to the Grundfos world of customised solutions Grundfos CR and NBG/NKG The basic CR and NBG/NKG pump ranges, which apply to almost any industrial solution, constitute the broadest range available. With our modular approach, we have made them even broader. The basics The basic CR pump range is available in four different materials − including cast iron, two grades of stainless steel, and all-titanium versions − in eleven flow sizes, capable of ­ rop ducing almost 50 bars of pressure, and with a variety­of shaft seals, rubbers, and supply voltages. The basic NBG/NKG pump range is available...

High pressure applications High pressure pumps are subject to demanding operating conditions. High pressure causes increased wear on pump parts and thus reduces pump life. To avoid unexpected downtime, we provide special pump and shaft seal design, bearings, etc. CR range • Filtration • Reverse osmosis • Steam boiler feed • Washing and cleaning • Industrial processes Hot water exposes pumps to operating conditions, which may lead to cavitation and/or cause wear on pump parts and thus reduce pump life. To avoid unexpected downtime, we provide solutions for steady steam production, poor inlet conditions,...

Difficult liquid applications When pumping dangerous and aggressive liquids, safety is all important. We provide solutions for aggressive and abrasive liquids, hazardous and hardening liquids as well as flammable liquids. CR range • Chemical industries • Pharmaceutical industries • Petrochemical industries • Refineries • Distilling plants • Paint industries • Mining temperature control Pumps used in applications involving temperature control are exposed to very low or very high temperatures as well as fluctuations. This extreme exposure stresses the materials due to thermal expansion or contraction....

Pumps used in industries, where a hygienic production is crucial, have to comply with strict requirements as to design, materials, surface quality, and cleanability. To ensure safe production, we provide solutions for applications with special requirements to design and cleanability in secondary hygienic processes. CR range • Pharmaceutical industries • Biotechnological industries • Food and beverage • Chemical processes Certain types of installations require a different pump design than the traditional vertical pump. We provide solutions for applications involving horizontally mounted pumps,...

Motors Grundfos Blueflux® technology represents the best from Grundfos within energy efficient motors and variable frequency drives. Products with Grundfos Blueflux® label either meet or exceed international legislation regarding motor efficiency. Grundfos Blueflux® labelled motors are standard in CR pumps with motor size 0.7575 kW and motors with integrated frequency converter from 0.75-22 kW. What follows is an overview of some of the most common motor variants offered by Grundfos. However, the overview covers only a fragment of the total motor range. Please do not hesitate to contact Grundfos if...

Shaft seals Extreme liquids call for extreme measures. Most pumps are used for watery liquids at temperatures below 120°C and pressures lower than 30 bar. When liquids go beyond these limits, special shaft seal solutions are required to guarantee reliable operation. Double shaft seal Back-to-back For applications involving dangerous, flammable, or very abrasive liquids, a double shaft seal, back-to-back, fitted in a pressure chamber is available. The pressure in the chamber must be higher than the pump pressure to prevent leakage. What follows is an overview of some of the most common shaft seal...

Pump modules All the made-to-stock CR pump modules can handle the most demanding of liquids and pressures - and be adjustable to virtually any requirement. Of course, the modules can be combined in multiple ways making it possible for us to provide you with a pump solution that matches your specific needs. CR pumps come in many flow sizes and various grades of corrosion-resistant stainless steel - and an all-titanium variant. What follows is an overview of some of the most common CR pump variants offered by Grundfos. However, the overview covers only a fragment of the total pump range. Please...

Other options In addition to the range of variants relating to the motor, shaft seal, or pump module of the CR products presented on the foregoing pages, Grundfos offers a variety of other customised solutions to suit almost any conceivable need or requirement that you may have. For instance a variety of connection options are available, as are pump models for additional corrosion requirements, hygienic demands or pumps in special colours. The following overview presents only a fraction of the many possibilities that we offer. Please do not hesitate to contact Grundfos if your requirements are...
