High precision and reliability
Iwaki AX series are highly precise and reliable metering pumps for chemical processes which achieve metering accuracy within ±1% (see Note 1), linearity within ±2% (see Note 3) and feature a driving unit specially designed for long-term continuous operation.
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.
Compact and lightweight
An integrated SL crank (Screwed L crank patented in Japan and other countries) 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.
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.
Note 1: Metering accuracy (repeatability) expresses
flow deviation from average rated capacity under steady state operating
conditions, when the capacity is repeatedly measured.
Note 2: Linearity indicates the deviation of stroke/capacity ratio
from the ideal straight line. Note that the linearity is not guaranteed.
Note 3: Reproducibility 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.
