Mechanically-driven diaphragm metering pumps AX-K series

Features of AX-K series

High Precision and Reliability

Iwaki AX series are highly precise and reliable metering pumps for chemical processes which achieve metering accuracy within ±1%*1, linearity within ±2%*2 and repeatability within ±2%*3.

*1 Metering accuracy expresses flow deviation from average rated capacity under steady state operating conditions, when the capacity is repeatedly measured.
*2 Linearity indicates the deviation of stroke/capacity ratio from the ideal straight line. Note that the linearity is not guaranteed.
*3 Repeatability describes the ability to reproduce a specific pump flow rate under a given set of conditions when capacity setting is varied. Note that the reproducibility is not guaranteed.

Durability and Reliability

Highly reliable for long-term continuous operation due to indigenous hydraulic system and drive parts with tried and tested built-in SL crank.

Compact and Lightweight

An integrated SL crank and worm reduction gear incorporated in the compact driving unit, reducing the pump installation area to a half or less as well as the overall weight to 2/3 or less.

Improved Cost Performance

The mechanical efficiency of the reduction gear as well as that of the entire pump is improved. In addition, the employment of a large-capacity pump head and the standardization of high-speed types have further improved the cost efficiency of the pump.

New Integrated Servo System With Built-in Positioner

An integrated servo unit with built-in positioner is employed, which directly controls the pump via mADC signal. This new type servo system has simplified both instrumentation work and also field adjustment.
