Bleach - One Tough Chemical

A highly corrosive and toxic chemical with strong disinfecting properties, Sodium Hypochlorite plays an ever increasing role in many industries. However, its corrosive nature and tendency to release tiny gas bubbles that can permeate non-metallic pumps poses a major challenge to conventional pumping techniques. Iwaki has over 50 years of experience successfully pumping Sodium Hypochlorite and many other aggressive chemicals.

The key to our success is on our magnets. Iwaki’s M-series pumps (MDM/MXM and MX-F)Pumps exclusively utilize the highest grade Samarium Cobalt(Sm2-Co17) Magnet capsules for better torque at elevated temperatures and proven superior chemical resistance. Comparatively, competitive magnetic designs use less expensive Barium Ferrite or Neodymium Iron Boron (Nd-Fe-B) magnets with little or no corrosion resistance to Sodium Hypochlorite. These low-end magnets typically react with their environment, frequently with disastrous results.

In addition, Iwaki M-series Sealless Pumps offer the following advantages over mechanically sealed pump designs:

• No dynamic seals
• Minimized maintenance
• Lower cost of ownership
• Increased reliability
• Elimination of seal flush systems
• Minimized number of parts
• Maximized safety
• More compact design
• Elimination of the single greatest failure mode - the seal
