Iwaki Industrial Metering and Magnetic Process Pumps
The world's most reliable sealless pumps for chemical dosing, water conditioning and aggressive fluid transfer — 65+ years of Japanese engineering excellence.
Our Two Main Pump Groups
Discover precise chemical feed or high-flow safe transfer systems to suit your requirements.
Metering Pumps
Flawless dosing from micro scale to high flow rates in water treatment, cooling tower, boiler and process lines with electromagnetic solenoid, brushless DC stepper motor and mechanical diaphragm pumps.
- IX Series: Smart brushless DC motor, 1:1000 turndown ratio, continuous linear flow.
- EWN-A / R Series: IP67 waterproof housing, 360 strokes/min high speed.
- CFD / HRP Series: Viscous polymer dosing and compact 24 VDC micro-fluid units.
- LK & GM-V Series: High-capacity motor-driven mechanical diaphragm pumps.
Magnetic and Process Pumps
Zero leakage, zero environmental pollution and maximum occupational safety when transferring acids, bases, solvents and ultrapure chemicals — thanks to magnetic coupling technology with no mechanical seal.
- MDM / MDW Series: CFRETFE-lined centrifugal pumps for heavy chemical industry, up to 300 m³/h.
- SMX / MX-F Series: Patented dry-run protected self-priming pumps.
- MD / MD-F Series: Compact OEM, laboratory and water treatment skid transfer units.
- TC-X Series: Ex-proof, compressed-air-driven double diaphragm (AODD) pumps.
