Product Overview
The KNF PM31177-86.16 is a precision-engineered diaphragm pump from the KNF PM series, designed for reliable transfer, metering, and evacuation of liquids and gases in demanding industrial environments. Utilizing a positive displacement diaphragm working principle, the pump features a flexible elastomeric diaphragm that oscillates via an eccentric-driven connecting rod, creating a sealed pumping chamber with no dynamic shaft seals and zero risk of media cross-contamination. This oil-free, self-priming design delivers smooth, pulseless flow with excellent chemical resistance, making it an ideal choice for critical fluid handling tasks in laboratory, medical, and industrial process systems where leak-tightness and long service life are paramount.
