    Certified Progressing Cavity Pump

The EHEDG (European Hygienic Engineering & Design Group) was founded in the last century at the end of the 90s to develop reliable standards in the hygiene sector. Just four years later, in 2002, NETZSCH obtained the certificate named after the Group for the NEMO Aseptic pump SA as a result of it passing the cleanability test. This pump with a flexible rod and an interior layout with no dead space has a fluid engineering design that prevents any product deposits. The cleaning ports are arranged tangentially and the pressure port eccentrically for residue-free self-emptying. The pump handles flow rates up to 140m³/h at pressures up to 24 bar.

From sensitive to abrasive

NETZSCH pumps with a flexible rod have been in use for more than 45 years in industrial applications, with this year making it 30 years in the hygiene field. NEMO pumps with a flexible rod have therefore been around for considerably longer than the EHEDG certification, because NETZSCH has always worked on the market-oriented development of the progressing cavity pump, thus also identifying the growing hygiene requirements and addressing them. Because the wear-resistant and maintenance-free flexible rod with no dead space is suitable for highly sensitive and abrasive products. The re-certification pending in 2019 in line with the new EHEDG standard EL class 1, therefore is a normal process without the need to develop a new product. Customers can rely on what is already tried and tested.
