FEATURES & BENEFITS:
LONGER IMPELLER LIFE & LOWER COST
• Impeller hardness of 58 HRC, greater than most solids in waste stream.
• Designed to pump and chop hard solids within the waste stream including abrasive substances like sand and grit
• Made to outlast standard Cast Iron impellers by more than 3 times
SUSTAINED NON-CLOGGING AND HYDRAULIC PERFORMANCE
• Resistant to abrasion and chips
• Impeller vanes remain in pristine condition even after pumping and chopping the most difficult solids
• Provide sustained non-clogging and hydraulic performance over a prolonged period of time
CONSISTENT HIGHER PUMP EFFICIENCIES
• Nickle hardened material provides higher hydraulic efficiencies over longer periods of time while reducing energy and operating costs
APPLICATIONS:
ABRASIVE APPLICATIONS – Standard Cast Iron impellers are suitable for pumping and chopping typical solids found in the waste stream. However, sand and grit cause Cast Iron impellers to erode and fail prematurely. Such applications include collection and treatment systems in coastal areas where abrasive solids are common. White Iron impellers are designed with abrasion resistance properties to withstand hard and abrasive solids.
HIGH I&I
Wastewater flow in a sanitary sewer system sometimes include unplanned components like groundwater infiltration and rainfall derived inflow. Small amounts of I&I are expected but may be considered excessive when it is the cause of overflows or bypasses. I&I events result in longer pump run times and exposure to unusual solids like sand, stones, grit, wooden barks and oils. Barnes White Iron impellers are designed to withstand hard and abrasive solids while providing reliable and trouble-free operation in high I&I environments.
OPERATION FLEXIBILITY
Pump Operation past best efficiency point can lead to cavitation and pitting on impellers. Cavitation leads to premature failure and requires frequent replacement of impellers. White Iron impellers are less prone to damage from cavitation-related problems and last three times longer than standard Cast Iron impellers.
