The Iwaki AX series pumps are hydraulic diaphragm metering pumps designed for highly accurate, long term chemical dosing under the heaviest operating conditions.

Extremely robust construction & long service life with highly stable capacity give this range unmatched reliability. Manual stroke length control is standard, with optional electric positioners also available. Automatic control via V.F. drive from 4-20mA signal is also possible.

Materials
Wetted materials including PVC, ceramic, PTFE, 316 s/steel, Hastelloy C and PVdF are available to handle nearly all industrial chemicals.

Accessories
Relief valves, loading valves, pulsation dampeners, calibration cylinders, servo stroke actuators, diaphragm rupture detectors and automatic controllers are available.

Capacities
80 models cover a huge range of capacities from 1.2 to 3240 litres/hour.

Discharge pressures up to 350 bar cover virtually any industrial chemical metering requirement.

Manual or automatic electric stroke length control range of 10:1 is available.

Automatic speed control range up to with speed turndown of up to 120:1 is possible using the MFC controller.
