The Smart Pump Module (SPM) combines our piezoelectric disc pumps with drive electronics and pressure sensing in a tightly integrated package, providing a miniature pump and pressure regulator solution all-in-one. Often eliminating the need for a proportional valve, it can reduce system complexity, size, and cost. The SPM can be fitted with any of our BL, XP, LT, or HP Series pumps, resulting a micro pressure controller with communication via UART, I2C or analog input, that provides maximum flexibility. The module’s closed-loop feedback from the pressure sensor allows for exceptional pressure and vacuum regulation, benefiting from the near infinite turndown ratio, pulsation-free output, wide dynamic range, and millisecond response time of the disc pump. This standalone pump module offers precision control that is not possible with conventional pumping technology, and it’s plug and play operation ensures simple system integration.

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)

The Lee Company has developed the Lohm Laws for defining and measuring resistance to fluid flow. The Lohm is defined such that 1 Lohm will flow 100 GPM of water with a pressure drop of 25 psi at a temperature of 80°F.
Always verify flow calculations by experiment.
