NETZSCH to showcase sanitary pumps at PACK EXPO 2026

NETZSCH Pumps USA will showcase its sanitary fluid handling portfolio at PACK EXPO International 2026, held October 18–21 in Chicago, Illinois. Demonstrating its technologies at Booth 7738, the company will feature pumps and transfer systems engineered specifically for the food, beverage, pharmaceutical, and personal care sectors. The display centers on solutions designed to convey shear-sensitive, viscous, and abrasive media while meeting stringent cleanability and hygienic regulatory standards.

Full Service-in-Place twin screw and peristaltic pumps
Highlighting the exhibit is the NOTOS Sanitary 2NSH Twin Screw Pump, displayed in a cutaway version to showcase its internal architecture. The FDA-compliant pump meets 3-A Sanitary Standards and incorporates NETZSCH’s Full Service-in-Place (FSIP) design, allowing operators to disassemble and service components quickly to minimize maintenance downtime. In parallel, NETZSCH will feature the food-grade version of its PERIPRO Peristaltic Pump. Utilizing large rollers with an FDA-approved nitrile hose and a hinged front cover for rapid CIP (Clean-in-Place) access, the pump consumes up to 30 percent less energy and requires 90 percent less lubricant than conventional shoe-style hose pumps.

Drum evacuation and progressing cavity systems
For processing bulk media, the NBE Barrel Emptying System utilizes a follower plate combined with progressing cavity or twin screw pumps to fully evacuate high-viscosity substances from drums and containers, minimizing residual product waste. Additionally, the company will exhibit its NEMO Progressing Cavity Pumps, including full stainless steel open hopper models. These sanitary and aseptic pumps deliver continuous, pressure-stable, low-pulsation conveyance across challenging materials, ranging from thin liquids to dense solids like ground beef, whole fruits, and vegetables.

Additional Context: Shear sensitivity and low-pulsation fluid displacement
This section details technical specifications and competitive benchmarking not included in the original product announcement.

In food and cosmetic processing, handling fluids containing delicate solids (such as whole fruit pieces or cosmetic emulsions) requires positive displacement pumps that generate low shear and minimal pulsation. High shear forces from traditional centrifugal impellers can mechanically degrade emulsion stability, cause phase separation, or pulverize suspended particulates. Twin screw and progressing cavity pumps mitigate this by creating sealed volumetric cavities that gently convey fluid axially along the rotor axis at constant volume. This volumetric displacement creates laminar flow conditions with virtually zero hydraulic pulsation. Furthermore, twin screw pumps operate with contact-free intermeshing screws, enabling them to dual-function: they can gently handle viscous products at low operational speeds (e.g., 200 to 500 RPM) and accelerate to higher speeds (up to 3,000 RPM) to circulate low-viscosity CIP fluids, eliminating the need for dedicated CIP return pumps in sanitary skids.
