Features of LK series
Various Types and Materials
Nine types (IWAKI original motor) and eight general purpose motor types are available to suit each user’s needs in accordance with feeding rate from small to large capacity. Also, material variation has been improved. Selection of the pump material most suitable for the applied liquid is possible with seven different types available.
High Performance and Application-Oriented Versatile Design
Discharge accuracy (stability) is within ±2% FS. Reliability is considerably enhanced through efforts to improve the linearity of the stroke / discharge ratio as well as the dispersion between stroke. Three types of joints flange, hose and union joints are standardized for the connections. The optimum piping system can be selected. (Only with 0.2 kW IWAKI original motor type)
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.

*1 The capacity is the value when maximum discharge pressure is applied (with pure water at room temperature). The value may be larger than indicated in the table if the discharge pressure is lower.
*2 The LK type is equipped with Iwaki original flange motor. The standard is 200V 3-phase, totally enclosed fan-cooled outdoor type. Other motors for different voltages, explosion-proof motors, or single-phase motors are available. LK-F, LK-A, B and C are to be installed with general purpose flange motors.
