Award Given to Micropumps

Servoflo is pleased to announce that EDN has named the mp6 micropump for air, gas & fluid delivery as one of the "100 Hot Products of 2012." The 2012 EDN Hot 100 highlights the electronics industry's most significant products of the year based on innovation, significance, usefulness, and popularity.

 

Based on piezoelectric diaphragm pump technology, the mp6 micropump delivers air, gas or liquid for low flow applications in a wide variety of industries. 

MP6 Micropump

The mp6 micropump is extremely small in size, measuring 30 mm X 15 mm X 3.8 mm. With a low power consumption of less than 200 mW, the mp6 is ideal for portable applications. Typical flow values are 18 ml/min maximum flow with 100 mbar backpressure for gas and 7 ml/min flow and 600 mbar backpressure for water. Various flow rates for other liquids are easily determined by readily available viscosity values. 

 

Unlike other solutions, the mp6 is an off-the-shelf micropump allowing users to quickly evaluate and integrate into their design.  Custom modifications can be made based on customer requirements. A polypropylene version (mp6-pp) is available for corrosive media. Sterilization is generally acceptable.

 

Various evaluation kits are available for purchase.

Applications reach across many industries for the mp6 micropump. In medical applications, drug delivery, infusion pumps, nebulizers, point-of-care platforms, cell culturing, and breath applications have needs to deliver small amounts of gas or liquids. Additional industries include consumer products and appliances, automotive and fuel cell, instrumentation products, sensor feeding and electronics.

 

David Ezekiel, Vice President of Servoflo, says, "We are very excited to offer this unique micropump. The strong, positive response to the mp6 introduction demonstrates the need for this product in many applications. We are pleased to broaden our range of solutions to our sensor customers."

 

"It's always a fun and enlightening challenge for the EDN editors to select the year's Hot 100 products, which has been an annual tradition at EDN since 1993. This year's selection not only reflects some technology trends that have been in place for a while, but also highlights some new trends that are just emerging, as well as a unique product or two that is in a class of its own," said Rich Pell, Executive and Chief Technical Editor, EDN.

 
PMFc3000 Mass Flow Sensors
PMF-3000 Series

The PMFc3000 Series of mass air flow sensors offer pin-compatible upgrade solutions to the popular AWM3000 series. Using the robust Posifa thermal flow sensor die, and incorporating the latest microcontroller technology, the PMFc3000 offers drastically improved interchangeability (less than 2% full-scale), temperature stability (less than 3% full-scale from 0°C to 50°C), and resistance to adverse environmental factors such as dust particles and water vapor that have plagued alternative solutions.

 

Tailored to meet the exact packaging and calibration specifications of AWM3000, the PMFc3000 also offers enhanced interchangeability by improving the output tolerance by 200% to less than 2% full-scale. Additionally the PMFc3000 is temperature-compensated to less than 3% full-scale drift from 0 to 50C. For more stringent applications, precise versions with 1% output tolerance are available. 

Pricing of the PMFc3000 is under $48 each at 1,000 pieces.
