In a class by itself - the LK is a motor driven, mechanically actuated diaphragm metering pump with a maximum capacity of 114 GPH (432 l/h) and maximum pressure of 225 PSI (1.5 MPa).
This expanded flow range makes the LK a perfect compliment to the E-Class Metering Pump Line.
The LK Series is ideal for chemical feed applications in a wide range of fields, including water treatment, chemical process, agriculture, mining and paper.
Stroke Adjustment
Accurate and reliable stroke setting is accomplished with a micrometer dial of the spring back stroke adjustment mechanism. This lockable mechanism is adjustable from 10 to 100%.
Drive
The heart of the LK is the dual-cam drive with a built-in worm gear type speed reducer. This compact & 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.
