7. 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
8. 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
