Products from KNF NEUBERGER GmbH: Technological Leadership in Diaphragm Pumps and Vacuum Systems
High-Performance Pumps for Laboratory and Industry: KNF as the Benchmark for Precision
KNF NEUBERGER GmbH is globally recognized for its pioneering technology in diaphragm vacuum pumps and chemically resistant liquid pumps. With proven series such as LABOPORT® and LIQUIPORT®, KNF offers solutions specifically tailored to demanding applications in laboratories, analytics, and process industries, including:
Distillation
Filtration
Liquid transfer
Desiccation
Rotary evaporation
KNF Diaphragm Pumps – Key Advantages
Precise Vacuum Control
KNF diaphragm pumps like the N 022 AN.18 or N 035.1.2 AN.18 provide consistent vacuum performance with high chemical resistance. Models with IP20 protection class are ideal for standard laboratory conditions.
Durability Through Robust Materials
Chemically resistant LABOPORT® models (e.g., N 820 G / N 840 G) feature PTFE-coated wetted parts—critical for handling aggressive media and thermal stress.
Low Maintenance & Energy Efficient
Thanks to oil-free diaphragm technology, downtime is minimized. At the same time, energy-efficient designs—like those in the NF 100/NF 300 series—enable sustainable operation.
Modularity & Accessory Compatibility
KNF offers a comprehensive range of accessories:
Steam tubes
Protective hoods
Pulsation dampers (FPD 1.06)
Power adapters
Structured membranes (e.g., EPDM280 for N811.18)
Product Highlights for Everyday Lab Use
LABOPORT® Diaphragm Pumps
Ranging from, this series covers everything from routine tasks to highly specialized processes. Models like LABOPORT® SH 820 G / SH 840 G integrate advanced control systems for automated vacuum regulation.
SC 920 G Vacuum System
This fully automated system with precise vacuum control and chemically resistant diaphragm pump is designed for complex tasks like rotary evaporation.
Promotional price:
RE 212 FW-G Rotary Evaporator
Used with KNF pumps, this evaporator ensures safe and efficient distillation under reduced pressure.
Optional safety hood available for—for greater protection of temperature-sensitive samples.
LIQUIPORT® NF Series for Liquid Transfer
Chemically resistant NF 100/300 and NF 1.100/1.300 pumps provide flexible solutions for handling aggressive or viscous liquids.
Typical flow range: 0.3 – 3.3 m³/h
Pressure performance up to 4 bar
Key Considerations When Purchasing a Pump
Application Requirements
For vacuum-based processes like distillation or filtration, a chemically resistant LABOPORT® pump is ideal. For liquid transfer, choose the LIQUIPORT® series.Performance Specs
Select based on required vacuum (e.g., 100 mbar) and flow rate (e.g., 3.3 m³/h for the N 035.1.2 AN.18).Material Compatibility
For corrosive media, opt for PTFE components or FKM seals (VE=2 ).Noise Levels
KNF pumps with optimized diaphragm design are ideal for noise-sensitive lab environments.Energy Efficiency & Integration
Accessories like pulsation dampers and condensers with mounting hardware help optimize lab setups.
Industry Trend: Automation & Chemical Resistance
Research and development labs are increasingly seeking fully integrable, software-controlled pumping systems. KNF addresses this demand with connectable controllers, intelligent regulation loops, and long-life components designed for aggressive media—making them ideal for modern lab and R&D environments.
