CD4MCu

• DUPLEX SS (TWO PHASE METALLURGY WHERE 316 IS ONLY
  ONE)
• 300 SERIES FOR CORROSION RESISTANCE
• 400 SERIES FOR STRENGTH AND HARDNESS
• CORROSION RESISTANCE EQUAL TO OR BETTER THAN
  316SS
• DOUBLE THE YIELD STRENGTH OF 316SS
• EXCELLENT RESISTANCE TO ABRASION AND EROSION

CD4 APPLICATIONSSULFURIC ACID

• 0-20 CONCENTRATION AT 140-160 OF
• 0-10 CONCENTRATION AT 185 OF
• TITANIUM DIOXIDE PLUS SULFURIC ACID
• TITANIUM SULFATE

CD4 IN SYSTEM ONE PUMPS

• CAVITATION CORROSION OCCURS WHEN LOW NPSH ALLOWS
  THE FORMATION OF VAPOR BUBBLES ON THE IMPELLER
• EXPLOSIVE FORCE OF BUBBLES RUPTURING
• REMOVE PROTECTIVE FILM OF SS LEADING TO
  CORROSION
• CAN REMOVE SMALL AMOUNTS OF METAL
• SYSTEM ONE PUMPS USE CD4 IMPELLERS TO WITHSTAND
  THE FORCES OF CAVITATION CORROSION AND EROSION
• GREATER HARDNESS, STRENGTH AND CORROSION
  RESISTANCE

CD4 IN SYSTEM ONE PUMPS..cont.

• CD4 BACKCOVERS AND CASINGS ARE AVAILABLE FOR
  EROSION AND ABRASION APPLICATIONS
• THE FACTORY WILL STOCK THE FRAME A
• 10 AND 13 IMPELLER SIZE WET ENDS
• PRICE IS GREATER DUE TO HIGHER CASTING COST AND
  SMALLER MACHINING QUANTITIES
