New, compact, low noise, high performance, diaphragm gas pump

Sep 01 2023

The new NMP 820 from KNF is designed for applications where low noise and vibration are of paramount importance; this micro diaphragm pump is exceptionally quiet for its high level of performance. The new NMP 820 delivers up to 2.1 litres per minute of free flow, operates at pressures up to 1.3 bar relative, and generates a vacuum down to 300 mbar absolute. Adding a second pump head to the NMP 820 increases free flow up to 3.6 l/min and enables an ultimate vacuum down to 100 mbar abs.

The versatile and quiet NMP 820.1.2's optimised design provides exceptionally low noise and vibration, making it extremely versatile and ideal for a wide range of applications where pumps with those qualities are critical. These include emissions monitoring, fuel cell and inkjet systems. For flexible and easy installation, a standard mounting plate is included. A four-wired brushless motor option is available for PWM pump control.
