Designed for applications where low noise and vibration is a top priority, the new NMP 820 from KNF is a micro diaphragm pump that is exceptionally quiet for its high performance making it ideal for applications where low noise and vibration are critical. The new NMP 820 available as a single-head pump, and as a twin-head pump with heads connected in parallel (for greater flow), or in series (for deeper vacuum).
Suited to many applications including medical diagnostic and analytical instruments, patient therapy and point-of-care devices, environmental measurement and monitoring equipment, industrial inkjet systems and more.
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.
KNF diaphragm gas pumps transfer or compress gases and vapors and generate a vacuum without contaminating the media. Different options are available for application-specific requirements related to size, motor type, control, voltage, chemical resistance, safety, vibration, noise, and temperature resistance. All pump types offer oil-free operation.
