Introducing the NMP 820 Micro Diaphragm Gas Pump: Compact, Low Noise, High Performance

03 August 2023

The new NMP 820 is ideal for applications where low noise and vibration are critical.

Designed for applications where low noise and vibration is a top priority, the NMP 820 is a micro diaphragm pump that is exceptionally quiet for its high performance.

Designed for Flexibility

With an impressive performance-to-size ratio, the new NMP 820 delivers up to 2.1 liters 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 increases free flow up to 3.6 l/min and allows for an ultimate vacuum down to 100 mbar abs.


The pump's optimized 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 portable medical equipment, point-of-care diagnostics, 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.
