Piezoelectric Micro Pump
The piezoelectric micro pump is a miniature, slim and lightweight diaphragm micro pump, which enables continuous micro fluid delivery. Metals are not used as wetted materials so this pump is highly chemically inert. Self priming, low noise, low power consumption and low electro-magnetic noise have been achieved.
List of Piezoelectric Micro Pump
Standard type
This is a miniature, slim and lightweight diaphragm micro pump driven by piezoelectric element. The driving voltage and frequency for operating the piezoelectric micro pump can be arbitrarily set by an external control signal, which enables a flow rate control. It is very suitable for integration into small equipment.
| Standard flow rate | 3 or 7ml/min |
|---|---|
| Maximum pump pressure | 45kPa |
| Outer dimensions | 25 x 25 x 4.8 (mm) |
Large flow type
This is a diaphragm micro pump driven by piezoelectric element, which is a larger size than the standard type so as to pump a larger flow rate.
| Standard flow rate | 20ml/min |
|---|---|
| Maximum pump pressure | 35kPa |
| Outer dimensions | 33 x 33 x 5.5 (mm) |
Built-in driver type
This diaphragm isolated micro pump is driven by piezoelectric element and it has a built-in driver board. The driver board enables the delivery of a constant flow rate by operating the pump at a constant voltage and constant frequency signal generated by a direct current voltage supply without making the particular waveform for the piezoelectric element. Flow rate and pressure range are not able to be adjusted.
| Standard flow rate | 3 or 7ml/min |
|---|---|
| Maximum pump pressure | 40kPa |
| Outer dimensions | 25 x 25 x 8.9 (mm) |
Driver and Controller for Piezoelectric Micro Pump
Driver Board MPD-200A (For research and development)
The MPD-200A is a thin, compact and lightweight driver board. It is a high voltage circuit board, specifically designed for the piezoelectric micro pumps. From a regular 5 VDC input, it readily generates approximately the 250 Vp-p, 40 Hz necessary for driving the pump.
