*Flow-graduation relationship varies according to the valve.

REDUCTION OF FLOW PULSATION

Piezoelectric micro pumps are small-sized, lightweight, and slim diaphragm micro pumps driven by a piezoelectric element. By considerably reducing the drive frequency and the drive voltage from the standard operating ranges, a piezoelectric micro pump alone can transfer μL/min level flows. However, significant pulsation is created at a low flow rate as represented by the blue line in the graph below.

By incorporating a micro needle valve to the discharging side of the piezoelectric micro pump, a low flow rate with almost no pulsation can be achieved. The red line on the graph below is an example that shows this remarkable reduction in pulsation. Reduced pulsation can also be achieved when combined with other pumps, such as peristaltic pumps.

ACTUAL EXAMPLE OF A LOW PULSATION MICRO PUMP MODULE

The low Pulsation Micro Pump Module is a module to adjust the flow of a piezoelectric micro pump at the μL/min level using a micro needle valve. The features of this module make it suitable for various fields, such as data from flow cytometers, cell culture equipment, etc.
