3K Series
The 3K series is a robust and versatile single headed liquid diaphragm pump. Highest quality con-rod and motor bearings ensure lowest power consumption and, combined with slow speed, maximum operational life.
The 3K series is offered with 2 different motors: brushed DC and brushless DC (BLDC).
› Flow rate to 1.5 l/min
› Robust / long life
› Slow running
› BLDC with speed control input and frequency (RPM) output
› Dual and Quad versions available
Double and Quad versions are available in the 3MD and 3MQ series as well as gas versions with 3K, 3KD and 3KQ.
A fixing bracket is included as standard.
