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.

What's In The Development Kit?

Watch this video of our Business Development Manager, John Watson, as he unboxes a Disc Pump Development Kit and explains everything that comes with it:

  • 1x Development Kit Motherboard
  • 1x General Purpose Drive PCB mounted on the motherboard, with protective cap
  • 1x pneumatic accessories kit (tubing, filters and connectors)
  • 1x precision orifice (used, for example, to bleed pressure from systems)
  • 1x cable kit for connecting Smart Pump Modules and valves to the kit
  • 1x USB cable for connecting the kit to a PC
  • 1x pump mounting kit (bolts and O-rings)

Note that Disc Pumps and valves must be purchased separately. This enables customers to select the exact model(s) that they wish to test. For help selecting the right model for your application, please speak to a Lee Sales Engineer.

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.
