LT Series Micropumps

The LT Series micropumps have been developed to serve applications with demanding operational life requirements across the medical, life science, environmental and industrial sectors. In common with all Disc Pumps, LT Series pumps combine silent operation, pulsation-free flow, millisecond response and high precision in a compact form factor.

  • Peak flow 1.20 L/min
  • Peak pressure 270 mbar
  • Peak vacuum -220 mbar
  • Life 5,000+ hours
Over 5,000 hours, cycling 20,000 times per second, LT Series pumps clock up
     more than 20 cycles for every year the universe has existed.


Model Pressure Flow Vacuum Life
LT-S2-023 > 270 mbar > 0.55 L/min > 220 mbar 5,000+ hrs
LT-P2-024 > 150 mbar > 1.20 L/min > 150 mbar 5,000+ hrs
  • Performance figures for 1 W operation.
  • 5,000 hours is typical time at which the normal operational wear process of the pump begins to affect performance ("t1"). Beyond t1, the pressure/vacuum capacity will reduce gradually; however the pump will continue to operate for many thousands of hours. t1 will be larger than 5,000 hours at power levels lower than 1 W.

  • TTP Ventus is actively developing higher performance pump designs. Contact us to discuss whether we have an alternative design that meets your requirements.
  • Note that the models above supersede the models LT-S2-019 and LT-P2-020.


Mounting Guidance
Mount in any orientation using compliant materials. If using mounting eyes on pump body, TTP Ventus recommends using four compliant o-rings (e.g. 1.42 ID x 1.78 CS Nitrile 70 Shore A) with two o-rings per mounting eye (one above and one below the eye), Nylon M2 bolt and threaded mounting stud (e.g. Wurth Elektronik 9774050243R). This mounting scheme isolates high-frequency vibration and prevents audible noise. Note that metal bolts are not recommended for this reason.
