A piezoelectric element drives this micro diaphragm pump. This pump is a larger size than the standard type to pump a more significant flow rate.
- Small-sized, lightweight, and slim.
 
- There is no metal in the wetted materials.
 
- Low noise and low power consumption.
 
- Flow rate is adjustable by changing drive voltage or drive frequency.
 
- Self-priming is possible.
 
Note 1: Details such as specifications, etc., may be changed without notice.
Note 2: This micropump uses a design for pumping liquid.
For this pump, there is a dedicated controller or driver that is required to operate this pump:
- Controller [MPC-200B]
 
- Driver [MPD-200A]
 
We do also have a pump with a built-in driver available:
- Piezoelectric Micro Pump - Built-In Driver-Type
