Micropumps for Environmental

Gas Sampling, Detection and Analysis
Tightening legislation and the growing global focus on air quality, worker safety and environmental emissions are driving the requirements for a new generation of measurement and monitoring systems. With its combination of performance, pulsation-free flow, controllability and size, the multi award-winning piezoelectric micropump, Disc Pump™, from TTP Ventus is well placed to enable the development of these systems, from gas samplers and detectors, to laboratory analysers and particle counters.

Enhanced Sensitivity
Disc Pump moves a few hundred nanolitres per cycle, resulting in negligible pulsation and improved signal to noise ratio.


Flow Control Precision
Set points can be held within a fraction of a percent — limited only by the resolution of control hardware / sensors.


Response Speed
Disc Pump has relatively little inertia. This means that it can respond to full-scale set point changes — including on/off gating — in a matter of milliseconds.


Dynamic Range
Unlike conventional pumps, Disc Pump has no stall speed, offering a near-infinite turn-down ratio.


Portability
Disc Pump weighs just 5 g (1/5 oz) and occupies a volume of 7 cm3. Also by eliminating the need for damping hardware, Disc Pump enables further reductions in size and complexity.

Disc Pump’s smooth flow is important to prevent noise on our sensors – the less noise the greater sensitivity we can achieve. It will also help us to easily maintain constant flow via a feedback loop – as our system will change over time this is an important benefit.
