LKN Series
In a class by itself – the LKN is a motor-driven, mechanically actuated diaphragm metering pump with a maximum capacity of 114 GPH (432 l/h) and a maximum pressure of 225 PSI (1.5 MPa). The LKN Series is ideal for chemical feed applications in a wide range of fields, including water treatment, chemical process, agriculture, mining, and paper. The LKN is the workhorse of the Iwaki metering pump products.
Stroke Adjustment
Accurate and reliable stroke setting is accomplished with a micrometer dial of the springback stroke
adjustment mechanism. This lockable mechanism is adjustable from 10 to 100%.
Drive
The LK utilizes a dual-cam system drive with a built-in worm gear type speed reducer. The
aluminum bronze worm gear and the tapered roller bearing provide efficient transmission of
motor power to the pump. This compact and rigid mechanism provides maximum wear resistance in
continuous operation over long periods of time.
Motors
All of the standard models employ totally enclosed fan-cooled motors which are vertically mounted
to save space. A variety of motor options are available, including explosion-proof and DC variable
speed motors for external control by a 4-20 mA input signal.
