Smart Pump Module

The Smart Pump Module (SPM) can be used to enhance our piezoelectric disc pumps with drive electronics and pressure sensing. This standalone pump module offers precision control that is not possible with conventional pumping technology. It is compatible with any of our disc pumps, including the BL, XP, LT, or HP Series pumps. The module’s closed-loop feedback from the pressure sensor allows for exceptional pressure and vacuum regulation, benefiting from the unique features of the disc pumps.

All disc pumps are RoHS compliant.

Electrical Operation
  • 5-wire interface:
  1. VCC – 3.5 to 5.5 V supply
  2. UART RX or I2C SDA (3.3 V)
  3. UART TX or I2C SCL (3.3 V)
  4. Ground
  5. 0 to 3.3 V, analog in
  • The integrated pump drive electronics provide an AC drive waveform of 20-22 kHz. Pump drive voltage must not exceed 48 Vrms. Power is limited to between 0 and 1 W into the pump for continuous operation, and up to 1.4 W for intermittent operation. Drive electronics also perform drive frequency optimization. Drive efficiency depends on the operating use case.

1Intermittent operation at 1.4 W drive power (into the pump). With intermittent operation, the mean power should be less than 1 W with a duty cycle period of less than 20 s. Operational life may be shortened when the mean pump drive power exceeds 1 W.
2Performance at 1 W measured after 30 s of continuous operation.
3Performance data presented was collected under normal temperature and pressure and ambient humidity conditions. Performance under other conditions may vary. In particular, note that performance decreases with altitude and may decrease at elevated temperature.
