IWAKI
Mechanically-driven diaphragm metering pumps LK series

Applicable to the many diverse needs of chemical feeding.

Main Features

Easy to use, multi-purpose design

  • This series includes nine of exclusive motor types and ten types of general-purpose motor types. This extensive lineup covers a wide range of application needs, involving everything from trace to large amounts of fluid. What’s more, the pump head is manufactured using various materials including PVC, fluororesin, and stainless steel, making the pump useful for almost all chemical dosing needs.

    • A wide variety of pump models and material compositions

  • This series includes the most economical and general-purpose pumps in our metering pump series. In fact, the first metering pump in Japan to use a PVC-molded pump head belonged to this series. Three types of standardized connections “flanges, hoses, and unions (0.2kW type only)” as well as a full line of accessories are available. What’s more, parts are manufactured at low cost and designed to be easy to use.

    • Highly durable pump drive unit

  • The pumps in this series use a worm-gear-type speed reducer which, though compact, is highly rugged and reliable. Since this unit is fully closed, oil-bath lubricating type, it can be installed outdoors. At the same time, it exhibits superior durability over long-term continuous operations.
