3MD Series
The 3MD series is the new compact version of the double headed 3K 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 economically exchanged.
The 3MD series is offered with 2 different motors: brushed DC and brushless DC.
› Flow rate to 2.5 l/min
› Robust / long life
› Detachable motor
› BLDC with speed control input and frequency (RPM) output
› Single (3K) and Quad (3MQ) versions are also available
Gas versions of this series is available with 3K, 3KD and 3KQ.
Fixing brackets are included as standard.
