KNF Micro Diaphragm Gas-Sampling Pump Uniquely Integrates Head Connections Inside the Housing

FLUID POWER: A new KNF micro diaphragm gas-sampling pump integrates head connections inside the housing for improved pneumatic performance in a compact and leak-tight package. This optimized design produces less pulsation and additionally allows for the housing to be closed and sealed for significant reduction in audible noise.

The pump ideally suits portable, battery-operated equipment used in a wide range of OEM applications, including gas sampling, explosives detection devices, anesthesia systems, and medical analyzers, among others.

Among features, the pump’s elastomeric diaphragm promotes high efficiency and delivers oil-free operation without any risk of contaminating the sampled gas.  Pumps can be specified either with an ironless core dc motor or with a brushless dc motor offering longer service life. PEEK housings and pump heads contribute high stiffness and temperature and chemical resistance.

Depending on model, these pumps can achieve flow rates to 2.1 l/m, vacuum to 650 mbar (11 inch Hg) absolute, and continuous pressure to 0.6 bar g (9 psig).  All are engineered to perform maintenance-free with low power requirements and are supplied ready for installation to operate in any position.

Chemically resistant versions are available and pumps can otherwise be customized to meet particular application demands.
