3KD Series

The 3KD series is an extremely compact, robust and versatile double headed gas diaphragm pump. Highest quality con-rod and motor bearings ensure lowest power consumption and, combined with slow speed, maximum operational life. This series additionally offers a unique detachable motor construction allowing contaminated heads to be ecconomically exchanged.

This series is offered with a quality brushed and versatile brushless motor.

› Flow rate to 18.0 l/min
