3. Highest Quality Components TB-Mag Series -Thrust Balancing

4. About Innomag: The Company Cont. • Fast prototyping • Fast lead times • Close cooperation with vendors • Highly Experienced Engineering design team

5. About Innomag – Pump testing Pump Testing • All wet-ends run tested • Disassembled and Inspected • Hydrostatic tested to 450 psi (31 bar) • 50Hz and variable speed testing available.

6. TB-Mag Series - Overview • ASME/ANSI and ISO models. • Continuous duty process pumps

7. TB-mag Series - Construction and features Construction and Features • Thrust balanced • Solids handling – unique to mag-drives • Permeation protected magnets • Single piece impeller • Totally open suction, lowest NPSHr

8. TB-Mag Series -Thrust Balancing Thrust Balancing • By creating distinct pressure zones in the pump, we can use those pressures to regulate & control the forces on the impeller • As the impeller moves forward, the pressure surrounding the inner magnet is reduced. This creates a restoring force. For momentary excursions, the impeller will bounce back. For prolonged changes, impeller will seek new equilibrium position

10. Wear rings create a clearance of only 0.005” (.127mm), anything larger can’t hurt the magnets or lock up the bearings. TB-Mag Series - Solids Handling 2D View Solids Handling

11. TB-Mag Series - Solids Handling Intro Superior Solids Handling TB-mags can handle solids up to 30% If it can travel through the vanes of the impeller, the pump can handle it Solids must be softer than SiC Start-up and shut-down must be evaluated Erosion must still be considered

12. TB-Mag Series - Tru-Seal Permeation Protection Tru-Seal Permeation Protection INNOMAG Single Piece Impeller • All fluoroplastics are inherently permeable. • While the fluoroplastics are extremely chemical resistant, the magnets are not. • Magnets are covered with a stainless can, welded air tight, before being encapsulated in plastic. This patented process is the best permeation protection available. • Greatly extends the impeller life due to fluorine or chlorine ions that permeate the plastic and attack the magnets. Lifespan for an unprotected impeller is between 6-14 months. • 2 piece impellers do not save you money as failures usually result in damage to both the impeller AND magnet assembly, completely negating the benefits of a 2 piece impeller.

13. TB-Mag Series - Cantilevered Design Cantilevered Shaft Design INNOMAG COMPETITION • Unique Design • Fully open suction • Lowest NPSHr • Better Efficiencies

14. U-Mag Series - Features Features The U-Mag Series Sub-ANSI model Thrust forward design Universal flanges for complete compatibility Virgin PFA option for semiconductor, pharmaceutical, or other high purity industry Same chemical compatibility as TB-mag with double welded impeller Low Cost

15. U-Mag Series - Construction U-Mag Construction Optional High Purity PFA Mates NEMA C-faced or IEC D-flange motors directly (no spacer plates required). Universal chemical resistance with fluoroplastic ETFE as standard. Universal foot supports entire pump load. Fully bonded ETFE or optional High Purity PFA liner - minimum of 1/8” (3 mm) thick and rated to full vacuum. Fully open suction for lowest NPSHr.

16. U-Mag Series - PFA PFA High purity fluoroplastic Ultra low contaminants, tested to less than 2 PPB. Excellent for semi-conductor, LCD and circuit board manufacturing

17. Applications - Semiconductor Industry Semiconductor/PCB Industry • High purity standards require PFA material on process/recycle streams • Acids and other etching solutions(HF, HCL, etc.) • Acetone • Hydrogen Peroxide • MEK, methanol, peroxide, TMAH • Xylene • Caustic
