In addition to the NOTOS® 2NSH hygienic twin screw pump in conventional design with optional heating jacket, we offer the NOTOS® 2NSH in a convenient FSIP® (Full-Service-In-Place) design as well as a barrel emptying system for your application. A combination of the highest product safety paired with the usual high NETZSCH quality. This will optimally equip you for any challenge in the hygienic area.
NOTOS® hygienic twin screw pump: Contamination-free and residue-free cleaning
Whether it's orange juice concentrate, fruit yoghurt or shampoo, all these products have one thing in common: Contamination turns the medium unusable and results in high reject costs. Therefore, we have made it our duty to design a pump for you in which any kind of contamination by operating media or wear-related abrasion can be ruled out. This is ensured by contactless conveying, in which the pumping elements do not come into contact with each other. The NOTOS® 2NSH can also be cleaned without leaving any residues using the CIP process (Cleaning-In-Place) and afterwards sterilized using the SIP process (Sterilization-in-Place). The system can be cleaned or sterilized in a circular or continuous process without prior disassembly. The combination of contactless conveying elements and the flange-mounted gearless three-phase motor enables a high pump speed. Thus, the flow speed of 1.5 m/s, which is decisive for the CIP process, is ensured. Residue-free cleaning is facilitated by the dead-space-free design of the pump. In addition, the all-metal construction is insensitive to high temperatures, which are essential for the SIP process.
Years of experience at NETZSCH in the area of multi screw pumps
The new hygienic twin screw pump is based on the 2NS model of the NOTOS® series, which has proven itself over decades. This series characteristically stands for high flow rates and pressures while requiring little space. "When the pump is in operation, chambers are formed by means of the two intermeshing, counter-rotating screws in combination with the pump housing. In these chambers, the pumped medium is continuously moved axially from the pump inlet to the discharge side", Gozzer explains. The NOTOS® 2NSH pumps the medium at flow rates of up to 200 m³/h. Delivery pressures of up to 16 bar are achieved.
NOTOS® 2NSH: One pump, three versions and countless advantages
The FSIP® version of the twin screw pump enables you to perform simple service and quick maintenance without removing the pump from the system or pipeline. When used in wear-intensive applications, where increased service and maintenance is to be expected, you save considerable capacities and thus costs. Furthermore, a conventional version is also available. It can be optionally equipped with a heating or cooling jacket. The jacket enables you to pump the medium at constant temperatures. This is an indispensable addition for applications where the pumped medium tends to harden or where temperature regulation is required. The third variant is the barrel emptying system: It guarantees you almost complete emptying in compliance with the strictest hygienic standards and safety regulations. With the new NOTOS® hygienic pump, you can efficiently convey even the most demanding media with absolute process reliability.
