The micro diaphragm gas-sampling pump features PEEK housings and pump heads that contribute to high stiffness and temperature and chemical resistance.

A new KNF (Trenton, NJ) micro diaphragm gas-sampling pump (Type NMP015.1.2) uniquely 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. Features include:

• An elastomeric diaphragm that promotes high efficiency and delivers oil-free operation without any risk of contaminating the sampled gas. 
• 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.
• Flow rates to 2.1 l/m, vacuum to 650 mbar (11 in. Hg) absolute, and continuous pressure to 0.6 bar g (9 psig).
