• No pins are used for the shaft with disc connection; this eliminates the possibility of electrolytic corrosion
• Self lubricated Plain bearingsfor both drive and non-drive end shaft ensures minimum bearing friction torque
• Choice of seat and disc material to suit media conditions and service requirements
• Adaptability to fit between companion flanges for all popular flange standards for the wafer style body. User Friendly
