19K Series

The 19K series is a single headed gas diaphragm pump. A combination of high pneumatic performance and damping chambers to reduce pulsation makes this a very versatile pump for wide range of applications.

High performance engineering plastics also allows use in high temperature applications.

Both brushed and brushless motor options are available.

› Flow rate to 4.3 l/min
› Damping chamber for low pulsation
› Encoder option available for rpm feedback
› Compact design

A liquid and gas / liquid mixtures verison of this pump (19K) is also available which runs at lower speed and stroke.

Flow control is available in combination with PWM Flow Controller.
