Micro-Diaphragm Sampling Pumps feature internal head connections.
Press Release Summary:
Available with ironless core DC motor or brushless DC motor, NMP015.1.2 Series features elastomeric diaphragm that enables oil-free operation without contaminating sampled gas. PEEK housings and pump heads contribute to temperature and chemical resistance. Depending on model, pumps achieve flow rates to 2.1 l/m, vacuum to 11 in. Hg absolute, and continuous pressure to 9 psig. Integrated head connections allow for housing to be closed and sealed for minimized noise and leak-tight operation.
Original Press Release:
KNF NMP015.1.2 Micro-Diaphragm Sampling Pump
with Uniquely Integrated Internal Head Connections
A new KNF 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.
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 in. 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.
