Stainless steel end-suction range - NBG/NKG

Stainless steel end-suction pumps – NBG/NKG range

Stainless steel has excellent corrosion-resistant properties, and is ideal for applications involving high temperature and pressure. A stainless steel end-suction pump is very often the best choice for use in industrial applications when the pumped liquid is challenging the wetted parts in the pump and the overall construction.

All Grundfos’ stainless steel end-suction pumps are available in two grades of stainless steel (EN 1.4408 and EN 1.4517 standards).

 

Examples on Applications

  • Food and beverage
  • Pharmaceutical
  • Biotechnology
  • Water treatment systems
  • Semi-conductor manufacturing
  • Oil and gas/offshore
  • Mining

 

Special solutions for difficult liquids

In industries where pumping of difficult liquids is part of daily operations, safety and reduced downtime is top priority. The Grundfos stainless steel end-suction pumps are based on a modular design which makes it possible to create variants that match the exact needs from the customer. This goes especially for shaft seal arrangements, shaft seal materials, and adaptation of different o-rings in the pump. Get the quick overview in the below list:
