LK Motor-Driven Metering Pump

Chemical Feed Solutions

The Iwaki LK Series metering pumps are motor-driven, mechanically-actuated diaphragm metering pumps.  This larger LK Series can achieve outputs up to 856 GPH (3240 l/h) and maximum pressures of 220 PSI (1.5 MPa). The LK Series is ideal for chemical feed applications in a wide range of fields, including water treatment, chemical process, agriculture, mining and paper.

With market proven results and years of experience, Iwaki has employed state-of-the-art pump technology in the development of the LK Series metering pumps. A robust design transfers rotational force from the motor to the diaphragm via a compact drive unit. The pump drive unit is a worm gear and dual-cam drive gear box design. The advantage of this economical design is reliability, quality, performance, and ease of operation.

Various materials and types

The LK Series offers a variety of sizes to fit a range of small to very large injection flow rates. Several material configurations and flexible motor options combine to satisfy a multitude of applications.

High performance and versatile design

The LK series has a discharge accuracy (repeatability) that is within ±2% FS. Reliability has been enhanced with the improvement in the linearity of the stroke and the discharge ratio of each stroke.
