The SPM-041 Smart Pump Module combines our award-winning micropump, Disc Pump, with drive electronics and pressure sensing in a tightly-integrated package. Its simple control interface, with digital and analog control options, makes the replacement of conventional pumps straightforward. This simplifies the design-in process, making it easier than ever for OEMs to take advantage of the key benefits of Disc Pump, including silent operation and exceptional performance.
The SPM-041 offers standalone high-precision pressure and vacuum regulation, benefiting from the pulsation-free output, wide dynamic range and rapid response speed of the pump. The module can be fitted with any of our BL, XP, LT and HP Series pumps.
Module Features
- Up to 600 mBar pressure, -400 mBar vacuum or 2 L/min flow depending on pump choice2
- Standalone pressure/vacuum regulation
- Compact & lightweight (11 g / 0.4 oz)
- Simple five-wire interface
- Analog and digital control options (inc. I2C or UART)
- No set up required: plug and play operation

The figures below summarise the peak performance across multiple models within each product line. Consult the individual datasheets for each product line to select the appropriate model for your application.
Ordering Guide
When requesting a quote or placing an order, please specify the module product code and required pump model, e.g.:
- SPM-041 Smart Pump Module
- XP-S2-028 XP Series Disc Pump
| Optional Extras |
|---|
| EK-01-0046 USB Power and Communication Cable - enables connection between the module and a host PC, providing power and enabling configuration, control and data-logging via the TTP Ventus Pump Control App over UART. |
| EK-03-0052 SPM Prototype Pneumatic Adapter Kit - enables convenient connection between the pump and on-board pressure sensor. Note that the adapters are made via SLA / rapid prototyping, and are intended for prototyping and development purposes; they are not suitable for use in end products. |
| EK-01-0006 SPM USB Flash Drive with Pump Control App, SPM manual and technical notes. Note that items included on the flash drive can be downloaded from the Resources section. |

Notes
- The SPM-041 module is not available for use in certain specific applications. Please discuss your application with us during the quotation stage.
- See individual pump datasheets for pump performance.
- Auto-detection function enables selection between I2C and UART. See User Manual for more information on auto-detection.
- Non-condensing gases only; ingress of liquid-phase water will halt pump operation.
- Liquid may be pumped indirectly in a “pressure-driven flow” / “air displacement” regime. Other gases / gaseous mixtures may be pumped. Contact TTP Ventus to discuss.
- Per ISO 226:2003 and related studies, 30 cm measurement distance.
- Disc Pump’s piezoelectric drive actuator has no stall speed. The pump can be controlled continuously between 0 and 100% maximum output.
- TTP Ventus recommends the use of an inlet filter with a pore size of 3μm or less in order to prevent the ingress of particulates that might otherwise limit the lifetime of the pump.

| User Manual for the SPM-041 Smart Pump Module. | |
| The TTP Ventus Pump Control App provides configuration, control and data logging for the SPM-041 Smart Pump Module. The optional extra EK-01-0046 USB Power and Communication Cable is required to connect the SPM-041 to a host PC. | |
| Our GitHub code snippet library provides examples of how to control the Smart Pump Module independently of the TTP Ventus Pump Control App. The initial examples provided cover a range of functions, including turning the pump on and off, setting drive power, closed loop control of pressure and reading back and plotting data. The code snippet library, which is hosted on GitHub, is intended to support customers after their initial evaluation of our pump technology, as they move on to developing prototypes and products. We welcome suggestions for how we can improve and build upon this repository; please feel free to share your ideas, feature requests and any bugs you identify with us at support@ttpventus.com. |
