High-performance micropumps introduced for medical and life science markets

TTP Ventus Ltd, a manufacturer of high-performance, silent micropumps for medical and life science markets, has announced the introduction of a range of new pumps that extend performance, delivering higher flow rates, higher pressures and longer lifetimes. This opens up new product innovation possibilities for applications including microfluidics research, medical diagnostics, therapeutic devices and wearables.

The new HP Series has been designed for applications requiring high pressure, with the first model delivering in excess of 800 mBar, doubling what was available with previous models. The ability to generate such high pressures from a small, controllable, and non-pulsatile pump offers exciting opportunities in microfluidics, particularly in so-called pressure-driven-flow or air-over-liquid systems. By moving the pump close to where the pressure or vacuum is needed, system complexity and size can be reduced significantly.

The new LT Series was developed for applications requiring long lifetimes, typically 5,000 hours or more. These models offer increased pneumatic performance combined with long lifetime. TTP Ventus plans to extend pump lifetime even further in the near future and expects to announce its first 10,000-hour pump in 2020.

In addition to these offerings, TTP Ventus has extended its BL and XP Series with four additional pumps. These provide increased flow rates of up to 2.1 litres per minute, enabling faster inflation with blood pressure cuffs or therapeutic cushions. The new pumps maintain the small size and silent operation of existing models, enabling discrete, wearable products which were not previously possible. Their increased efficiency is valuable for battery-powered products, while precise controllability means that components such as proportional valves can be made redundant.
