Micro Pump

Piezoelectric micro pump - SDMP SERIES

The Piezoelectric Micro Pump is a miniature, slim and lightweight diaphragm micro pump that enables continuous micro fluid delivery. The metals are not used as wetted materials so this pump is highly chemically inactive. Self priming, low noise, low power consumption and low electrical magnetic noise have been achieved.

Standard flow rate 3 or 7 ml/min
Max. pump pressure 45 kPa
Outer dimensions 25 x 25 x 4.8 mm

Driver and Controller for Piezoelectric Micro Pump
The MPD-200A

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.

Controller MPC-200B

The MPC-200B is a compact and lightweight controller that can provide the high voltage power output necessary to drive the piezoelectric micro pumps. It is user-friendly with a front panel digital display for configuring the output voltage and output frequency, and a memory function to store the most recently used settings.

Peristaltic pump – RP-Q SERIES:

• The Peristaltic Pump is designed for pumping liquid/ fluids.
• As it is so compact, it can sit on the tip of a finger.
• Discharge rates of up to 3.0 ml/min.
• DC motor is driven and low power consumption.
• Can be operated by battery.
• Easily replaceable pump head (QII & QIII).
