Thanks to the short charging time of 50 minutes and the spare battery, there is no downtime. The pressure and the delivery volume can be steplessly adjusted from 0 – 207 bar. Opposite to electric diaphragm pumps the motor of these units stops as soon as required and pre-adjusted working pressure is reached. Therefore also an accustic control during injection is possible.
