To meet consumer demand for a compact, energy-efficient blood-analysis system, a leading medical-device manufacturer turned to Hargraves Technology to advance its product technology.

Advanced but compact medical devices have produced challenges for their development engineers to incorporate fluidic components that are durable, reliable, pack more performance, and are highly efficient To meet consumer demand for a compact, energy-efficient blood-analysis system, a leading medical-device manufacturer turned to Hargraves Technology to advance its product technology

By applying more efficient motors and advanced pump-head technology, Hargraves developed a micro diaphragm vacuum pump and compressor that halved power consumption versus previous-generation blood analysers.

The CTS miniature diaphragm pump measures just 20.3 x 44.2 x 32.3mm, yet delivers up to 2.5 litre/min unrestricted flow, pressure to 1.65bar(g), and vacuum service to 670mbar.

Three configurations include: brushless DC motors for long life, brush motors for low cost, and coreless motors for maximum energy efficiency.

All are available in 6, 9, or 12V DC versions.

Operating current varies from 50 to 500mA, depending on motor type, voltage, flow and pressure requirements.

The single-head micro diaphragm pumps and compressors feature an advanced proprietary diaphragm elastomer for long life and increased fluidic operation.

Ports are barbed to handle 0.125in flexible tubing.

The CTS micro diaphragm compressors and vacuum pumps are dynamically balanced to minimise noise, operating at levels as low as 45dB.

The unit is suited for use with most gases over an operating temperature range of 5 to 50C.

The oil-free designs maintain system purity, and are commonly used on FDA-approved systems.
