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...

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...

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...

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...
