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 motor and mechanical diaphragm pumps.
- IX Series: Brushless DC (BLDC) motor, turndown ratio up to 1000:1, low-pulsation feed.
- EWN-A / R Series: IP65 water/dust-proof housing, 360 strokes/min high speed.
- CFD / HRP Series: High-purity PTFE/PFA dosing for semiconductor chemicals (CFD) and compact 12/24 VDC OEM units (HRP).
- LK & GM-V Series: Motor-driven mechanical diaphragm metering (LK) and magnet-drive gear pump for pulsation-free dosing (GM-V).
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: Fluororesin (CFRETFE / ETFE / PFA) centrifugal pumps for heavy chemical industry, up to 300 m³/h.
- SMX / SMX-F Series: Self-priming pumps with patented dry-run resistant design.
- MD / MD-F Series: Compact OEM, laboratory and water treatment skid transfer units.
- TC-X Series: ATEX-compliant versions available; compressed-air-driven double diaphragm (AODD) pumps.

Superior Advantages of Iwaki Engineering
Patented technologies delivering process safety, zero downtime and long service life.
Sealless Zero Leakage
No mechanical seal wear or leakage risk. 100% guarantees human and environmental safety when handling aggressive, toxic and explosive chemicals.
Patented Dry-Run Tolerance
The non-contact rear bearing design and high-purity SiC/ceramic components prevent pump damage during dry-running conditions.
Superior Chemical Corrosion Resistance
Full resistance to concentrated sulphuric acid, caustic and solvents with carbon-reinforced ETFE (CFRETFE), pure PVDF, PFA and alumina ceramic wetted surfaces.
Precision Automation & IoT Drive
100% plug-and-play digital integration with 4-20 mA proportional speed control, pulse input, MODBUS, Profibus and Walchem controllers.
