Product Specifications:

• HP:  7.5
• Voltage:  208-230
• Discharge:  4"
• Full Load Amps:  22 A
• Lead Length:  50'

Features & Benefits:

• Energy-Efficient Solution: Air-filled IE3 premium-efficient Class H motors, available on 7.5 to 20HP models, offer improved motor efficiency, prolonging pump life and reducing total cost of ownership
• Built to Last: AISI 420 stainless steel pump shaft designed for long resistance life and increased strength
• Optimal Performance: Semi-open impeller improves efficiency and solids handling capability
• Improved Durability: Ductile iron impellers are less brittle when handling rigid debris versus competitive cast iron versions
• Simplified On-Site Maintenance: Field adjustable wear plate provides clearance between the impeller and volute for simplified maintenance, minimizing operational downtime without the need and additional cost of a replaceable wear ring
• Longer Seal Life: Standard dual silicon carbide mechanical seals have low thermal expansion and higher abrasion resistance
• Protective Seal Fail Probe: The seal fail probe will immediately send a signal to the control panel once the first mechanical seal is breached to alert for needed service
• Corrosion Resistance Coating: All castings are powder coated and offer a smooth finish that is easy to clean
• Retrofit Capabilities: Optional elbow adapters and rail systems components available
