Maag Pump Systems AG introduced a product at K 2010 that it says is unique — a gear pump that offers pulsation-free extrusion.
The company, an exhibitor at the show in Dusseldorf, said the innovation offers many benefits, especially for companies extruding very thin, demanding products like battery release films.
“It's the birth of a new machine. It really is,” said Lee Larson, calculation engineer for gear technology at Maag's headquarters in Oberglatt, Switzerland.
“It's something brand new, and we're waiting to see how the market will react. I'm convinced that it's needed,” Larson said in an interview after the formal unveiling of the Extrex Synchro gear pump on Oct. 28.
Maag's engineers used special software to eliminate pulsations. Maag said the technology allows for very tight tolerances, plus energy and rawmaterial savings.
Roland Moerker, product manager for extrusion, said the Extrex Synchro is still in development, and will begin field trials in the first quarter of 2011 at a customer's site. The pump is scheduled to be commercially available in 2012, he said.
