Sundyne Announces the ANSIMAG ALI (Aggressive Liquid ISO) Series of Chemical Service Pumps

Ansimag ALI ISO Chemical Pump

Expanded ISO Range and Optimized Hydraulics Bring the Benefits of ANSIMAG ETFE-Lined Sealless Magnetic Drive Pumps to ISO Markets   


Arvada, Colorado, May 11, 2022Sundyne, a global leader in the design and manufacture of pumps and compressors, today announced the ANSIMAG ALI (Aggressive Liquid ISO) family of ETFE-lined sealless magnetic drive pumps.

ANSIMAG pumps are specifically designed to handle aggressive corrosive or acidic liquids in chemical processing applications, including Chlor-Alkali, isocyanates, plastics & polymers, battery manufacturing, agro-chemicals and water & wastewater applications.  All ANSIMAG wetted parts are molded ETFE (Ethylene Tetrafluoro Ethylene) components that can safely handle a wide range of corrosives and solvents.  A patented, fully encapsulated magnetic drive hermetically seals the inner magnets to isolate them from process fluid and maintain magnet integrity for the life of the unit.  An aramid fiber reinforced containment shell delivers unprecedented reliability and protection against water hammer.

The new ALI family brings all of the ANSIMAG benefits to ISO markets, supporting the dimensional requirements of ISO 2858 with specification conformity to ISO 15783.  Eleven different ISO-compliant pump sizes provide flows up to 140 M3/hr; Heads to 90m; temperatures from -30 to 1200 C; and working pressures up to 19 bar.

The new ANSIMAG ALI line complements the extensive HMD Kontro CSI line of metallic sealless mag drive pumps.  HMD Kontro CSI pumps support all ISO standards and feature various frame sizes to accommodate an even wider range of flow & pressure requirements at higher temperatures.  The combination of CSI and ALI offers customers the widest range of reliable, sealless mag-drive options, in ETFE or metallic materials of construction, to address any chemical processing application.  All ANSIMAG ALI and HMD Kontro CSI pumps come with the worldwide backing of Sundyne’s global support network.

ANSIMAG design features brought to ISO markets via the new ALI line include: 

  • Zero Leakage – Sealless Design completely eliminates possible leakage with only a single fully-contained O-ring.
  • Chemically Resistant Materials – Carbon Fiber reinforced ETFE is resistant to virtually all chemicals.
  • Secondary Containment – is available for applications requiring an additional layer of protection.
  • Corrosion Protection – Powder Coated metallic parts provide excellent chemical resistance and superior impact/scratch resistance to maintain coating integrity.
  • Durable Construction – Ductile iron exterior is designed for heavy-duty chemical applications.
  • Fully-Encapsulated Inner Drive – Provides unsurpassed resistance to chemical attack by hermetically sealing the inner magnets and isolating them from the process fluid.
  • Easy Service – 9 wetted parts and a back pull-out design enables service without disconnecting the casing from piping and without requiring special tools.
  • Close Coupled – Completely eliminates the need for shaft alignment & bearing frame related maintenance in a smaller footprint.
  • Energy Efficient – Non-metallic materials completely eliminate eddy current generation allowing for greater efficiency.


“ANSIMAG ALI sealless mag-drive pumps provide affordable replacement options for aging ISO-sized pumps and the newly-expanded line covers a wide range of sizes & external dimensions to facilitate easy replacements without changing piping or baseplates,” said Sundyne’s Global Vice President of Chemical & Industrial, Colin Guppy.

More than 70 years ago, HMD Kontro invented the magnetic drive pump, and today, the HMD CSI sealless pump line sets the standard for metallic magnetic drive ISO pumps.  Since 1985, more than 50,000 ANSIMAG sealless, non-metallic mag-drive pumps have been deployed to handle harsh & corrosive chemicals in a variety of industries.  “The introduction of the ANSIMAG ALI line brings a rich heritage to ISO markets, and the combination of ALI and CSI offers customers a one-stop-shop for sealless pumps to address any harsh & aggressive pumping application,” concludes Colin Guppy.
