NETZSCH NOTOS® 2NSH Screw Pump

NETZSCH NOTOS is made of AISI 316L stainless steel and polished according to international standards, making it
easy to clean (CIP) and to sterilize (SIP). As there is no contact between the rotating parts, the pump speed
can be increased. Therefore cleaning can be carried out without the need for an auxiliary system.

Broad range of applications

  • Food industry: dairy products,delicacies, ketchup, sauces,confectionery and baby food
  • Beverage industry: fruit juices,syrups, concentrates, breweries
  • Cosmetic and pharmaceutical industry: creams, active substances, ingredients
  • Chemical industry: adhesives,solvents, paints, varnishes andplastics

Screw Pump General Characteristics

NOTOS® 2NSH meets the high requirements of food, beverage,chemical, pharmaceutical and cometic industries:

  • Metal parts made of stainless steel
  • High suction capability (low NPSHr)
  • No contact between the rotating parts
  • Reversible flow
  • Low pulsation
  • No dead spaces
  • Smooth feeding of the pumped media

Screw pump is a part of the dry compressed gas transfer pump series. They are positive displacement pumps that use one or more screws to move fluid or water along the screw shaft. These screws interlock to pressurize the fluid and move it into the system. These screws engage each other and reciprocate in the cavity of the cylinder. They are often used in industrial vacuum applications, often in combination with Roots blowers, and as oil-free roughing pumps in high vacuum and ultra-high vacuum systems. Please check out the description of various pumps.

Netzsch screw pump is mostly used on fluids of a higher viscosity, moving these fluids with screw pumps results in energy efficient and a relatively compact machine when compared to other pump types i.e centrifugal pump.

The operation of a screw pump is much softer with less pulsations, less noise and fewer vibrations, meaning longer lifespan. Gear pumps are noisier, more turbulent and cause more vibrations for the pump and pipework to withstand causing a lower working life.

Archimedean screw pumps are capable of pumping heavily contaminated surface water or sewage, and even sand if they are specially designed for this purpose. The head is purely geodetic and ranges up to 6 m at efficiencies between 60 and 80 %.
