KNF diaphragm micro pumps and mini pumps are extremely compact with patented technology that guarantees high performance. Providing design engineers installation flexibility in virtually any environment, KNF micro pumps for air and gas offer miniature, yet durable and efficient solutions to transfer, evacuate, or compress media in the smallest of spaces.

Small, lightweight, and powerful, KNF micro pumps are perfect for portable, battery-operated medical device/diagnostic applications including: aspiration, waste-handling, anesthesia monitoring, tissue sampling, blood pressure gauges, negative pressure wound therapy, sample transfer and cleaning. Additionally, diaphragm pumps from KNF Neuberger are well suited as gas sampling pumps for environmental and industrial hygiene applications, such as: confined space monitors, homeland security detectors, workplace ambient air quality monitors, waste gas and flue gas analysis, etc.

One of the most important features of KNF micro pumps, mini pumps, and larger series diaphragm pumps is a unique modular system - developed to meet specific performance requirements with spec-driven configurations, materials, and accessories from which to choose. Multiple motor options and/or inter-head connections are also available depending on your requirements.
