Hydraulic diaphragm metering pumps AX-L/AX-M series

Features of AX-L / AX-M 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.
The SL crank features a solid cam and connecting rod. The cam is coupled to the crank via 10 or more screw threads. Owing to the wide area supporting the piston load, it is free from problems such as play and biting due to crank wear during longterm continuous operation.

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.
