3KQ Series
The 3KQ series is an extremely compact, robust and versatile quad 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 high quality brushed motors.
› Flow rate to 28.0 l/min
› Robust / long life
› Single and Quad versions available.
Single and Double versions are available in the 3K and 3KD series as well as liquid versions with the 3K, 3MD and 3MQ.
Fixing brackets are included as standard.
Flow control is available in combination with PWM Flow Controller.
