Overview of the NEMO® progressing cavity pump range
The NEMO® progressing cavity pump range is built on one simple but powerful idea — using a helical rotor turning inside a matching stator to move liquids gently, continuously, and with minimal pulsation. This principle allows precise metering and consistent flow, even for materials that are viscous, abrasive, or contain solids.
Unlike centrifugal pumps that rely on high-speed impellers, NEMO® pumps work like a conveyor belt for liquids — pushing product steadily without turbulence. The result? Gentle handling, high efficiency, and reliability across industries like wastewater treatment, chemicals, food, and oil & gas.
Key advantages of NEMO® progressing cavity pumps
| Advantage | Description |
|---|---|
| Gentle pumping | Ideal for shear-sensitive fluids and food products |
| Consistent flow | Delivers precise, pulsation-free discharge |
| Versatility | Handles viscosities from water-like to paste |
| High suction lift | Effective even with challenging inlet conditions |
| Low maintenance | Modular design, FSIP® easy-service concept |
These pumps are available in multiple geometries and configurations, each tuned for specific conditions — from small dosing volumes to heavy slurries.
Industrial series: BY, SY, and FSIP® pumps
When it comes to industrial fluid transfer, NEMO® BY, SY, and FSIP® pumps are the workhorses. They are designed for tough, continuous-duty environments in wastewater, chemical, and general process industries.
The NEMO® BY pump features a space-saving block construction, directly connecting the drive to the pump. Meanwhile, the SY model uses a bearing housing and free shaft end, allowing flexible coupling with any drive system. For users focused on fast serviceability, the FSIP® (Full Service in Place) version allows rotor, stator, and mechanical seal replacement without removing the pump from the pipeline — drastically cutting downtime.
Industrial range comparison
| Model | Design | Typical Use | Key Benefit |
|---|---|---|---|
| BY | Compact block design | Wastewater, general industry | Space-saving and economical |
| SY | Bearing housing + free shaft | Chemical and heavy-duty tasks | High flexibility for drive systems |
| FSIP® | Modular inline design | Frequent maintenance sites | Simplified service and reduced downtime |
The industrial NEMO® series is all about performance, durability, and maintenance efficiency — exactly what plant engineers need for 24/7 reliability.
Hygienic and aseptic series: BH, SA, and SH Plus pumps
In the food, beverage, and pharmaceutical industries, cleanliness and gentle handling come first. The NEMO® BH, SA, and SH Plus pumps are built to meet strict hygiene standards with smooth surfaces, CIP/SIP capabilities, and stainless-steel construction.
The BH model is ideal for standard hygienic processes, while SA serves aseptic environments requiring sterile conditions. The SH Plus series takes it further, offering high-grade finishes and customizable sealing options to prevent contamination.
Comparison of hygienic NEMO® pumps
| Model | Application | Highlights |
|---|---|---|
| BH | Food, dairy, cosmetics | Hygienic, CIP-compatible |
| SA | Pharmaceuticals, sterile processes | Aseptic sealing and sterilization options |
| SH Plus | Premium hygiene applications | Polished stainless surfaces and superior seals |
Each hygienic NEMO® pump ensures product integrity and compliance with FDA and EHEDG standards.
Dosing and metering pumps: NEMO® C.Pro
Precise dosing can make or break a process line — and that’s where the NEMO® C.Pro shines. Compact, efficient, and highly accurate, this dosing pump handles low flow rates with consistent precision.
The C.Pro is built from advanced synthetic materials, offering chemical resistance and compact dimensions. It’s the perfect solution for dosing additives, enzymes, or colorants in industrial and food processes.
Why choose NEMO® C.Pro?
- Compact and lightweight
- Easy to integrate into skid systems
- Excellent chemical resistance
- Pulsation-free dosing accuracy
When you need precise metering without complex setup, the C.Pro is your go-to choice.
Hopper and feeding systems: BO, BF, and BT pumps
Highly viscous or solid-laden materials can be challenging to convey — unless you use a hopper-type NEMO® pump. The BO, BF, and BT series are designed with large rectangular inlets, feeding screws, or bridge breakers to move thick, sticky products smoothly.
The BO pump includes an integrated feed screw, ideal for dewatered sludge or dough-like materials. The BF adds a bridge breaker for extra feeding support, while the BT design is immersible, making it perfect for tank emptying and difficult suction applications.
Hopper range comparison
| Model | Special Feature | Typical Application |
|---|---|---|
| BO | Feed screw | Sludge, dough, pulp |
| BF | Bridge breaker | High solids, sticky pastes |
| BT | Submersible/immersed | Tank drainage, viscous fluids |
These models show why NEMO® is a leader in difficult material handling — nothing stops their feeding power.
Special applications: Multiphase, L.Cap, and MY series
For extreme environments like oil fields, mining, or chemical plants, NETZSCH offers special-purpose NEMO® pumps such as Multiphase, L.Cap, and MY.
The Multiphase pump handles mixtures of oil, water, and gas directly from wells — reducing the need for separators. L.Cap models manage huge flow rates and high pressures, while MY uses magnetic coupling for leak-free performance with toxic or hazardous media.
Special series overview
| Series | Function | Industry |
|---|---|---|
| Multiphase | Handles liquid-gas mixtures | Oil & gas |
| L.Cap | Large capacity, high pressure | Mining, energy |
| MY | Magnetic coupling, no seal | Chemical, toxic fluids |
These series extend the NEMO® technology into demanding territories — where safety, pressure, and gas handling matter most.
