NETZSCH Twin Screw Pump
The benefit to the customer
NETZSCH presents the Sanitary Twin Screw Pump with exclusive full service-in-place. Designed to optimize the transfer at low and high working pressures (up to 230 psi / 16 bar) of fluids with low and higher viscosity, such as chocolate, fruit, yogurt, and juices, and pumping them while keeping the integrity and natural properties, without any quality loss. This pump is a practical solution that adds more efficiency and technology to the process. The pump is made of AISI 316L stainless steel and polished according to international standards, making it easy to clean (CIP) and sterilize (SIP). As there is no contact between the rotating parts, the pump speed can be increased. Therefore, cleaning fluid (CIP fluid) and the 2NSH itself can carry out the main product without the need for an auxiliary system or a separate CIP pump.
The NETZSCH Twin Screw Pump meets the high

Large capacity and pressure range
This pump covers a wide performance range and so offers wide flexibility of use.
∙ Flow rate up to 880 GPM / 200 m³/h
∙ Pressure up to 230 psi / 16 bar
Small space requirements due to the compact design, having two options for mounting: with foot or flange.
A broad range of application examples:
∙ Food industry: dairy products, delicacies, ketchup, sauces, confectionery, baby food.
∙ Beverage industry: fruit juices, syrups, concentrates, breweries.
∙ Cosmetic and pharmaceutical industry: creams, lotions, ingredients.
∙ Chemical industry: adhesives, solvents, paints, varnishes, and resins.
∙ Versatile use eliminating the need for a CIP pump
∙ Easy maintenance: simple assembly/disassembly
∙ Flexibility: use the same equipment for pumping fluids with low or high temperature/ viscosity
∙ No damage to the pumped product.
Four Different Pitch Screw Options:
Stainless steel screws with a high-efficiency profile that allow more flow per revolution and low fluid shear:
∙ Balanced with the high suction capability
∙ All screw pitches are the same diameter and are interchangeable
∙ Simple replacement without disassembly of bearings
∙ Pitch change allows change of flow, pressure range, and solid size with the same pump.
Product flexibility Due to the operation principle and the design of this positive displacement pump, fluids with the following properties can be conveyed:
∙ Low to high viscosity
∙ With/without solids
∙ Shear sensitive and shear-stable
Innovative Full Service-in-Place (FSIP®) design for simplified maintenance (Optional)
NETZSCH implemented FSIP® as a design concept in many products. It simplifies maintenance and the life of service staff. Thus it is possible to fully disassemble and assemble the screws and the mechanical seal without removing the pump from the processing line. As a result, servicing downtimes are significantly reduced. FSIP® is an intelligent technological solution that brings even more confidence and reliability to your processes.
Adding a jacket for heating or cooling allows temperature control of the fluid (optional):
The standard version of the Sanitary Twin Screw Pump can be equipped with a heating or cooling jacket. The jacket is installed around the entire housing in which the screws are located. An external, independent circuit heats or cools the jacket. This pump is perfect for applications where the pumped fluid tends to harden or requires temperature control to guarantee its quality.
