Benefits/Features
• Gauge taps at the suction and discharge connections for complete monitoring flexibility
• Annular pressure reducing clearance with impeller balance holes to reduce axial thrust
• Precision-cast, dynamically balanced double suction impeller minimizes vibration and maximizes bearing life
• Precision bearings and shaft design limit deflection at the seal face
• Additional lower radial bearing support with a water flush line pulling from the pump discharge
• Mechanical seal is replaceable without removing the motor
• Rigid coupling to eliminate the requirement for field shaft alignment
• Standard case wear ring
• Mechanical seal is standard in carbon vs. silicon carbide (optional: tungsten carbide) with an external seal flush line
• Every pump hydrostatically pressure-tested
• Optional ductile iron case with 250-lb pump flanges
• Standard construction with stainless steel shaft
