Mechanical / Hydraulic

Design Features:

• Back Pull-Out
• Fully Open Impeller
• External Impeller Adjustment
• Renewable Wear Parts
• Maximum Sealing Flexibility
• Heavy Duty Construction
• Maximum Parts Interchangeability
• Condition Monitoring

Materials of Construction:

• Stocked: Cast Iron and 316 Stainless Steel.
• Available: Any machinable alloy including 317SS, 317LSS, 316LSS, Alloy 20, CD4MCuN, 6-7% moly, Titanium, Hastelloy B and C.

Key Features:

• External Impeller Adjustment: Easily reset to maintain hydraulic performance, delivering long-term energy savings.
• Heavy Duty Shaft: Designed for continuous service under severe conditions, with low deflection for extended seal and bearing life. Features a dry shaft design, sealed by O-rings.
• Fully Open Impeller: Special warped vane, heavy-duty open type for paper stock handling. Back pump-out vanes reduce stuffing box pressure and help prevent solids from entering the sealing chamber.
• Renewable Wear Parts: Suction sideplate, impeller, stuffing box cover, shaft sleeve, and throat bushing are easily replaced for low maintenance costs.
• Optional TaperBore™ Seal Chamber: Features an enlarged bore for improved lubrication and cooling of the mechanical seal. The tapered throat and vane particle ejector keep solids away from seal faces.
• Patented Condition Monitor: Constantly measures vibration and temperature at the thrust bearing, with colored LEDs indicating general pump health for early warning of improper operation.
• Standard Labyrinth Oil Seals: Prevent contamination of lubricant for extended bearing life.
• Maximum Sealing Flexibility: Includes a Dynamic Seal option for applications where conventional mechanical seals or packing require outside flush, eliminating external seal water. The 3175 is easily field converted to Dynamic Seal.
• Vertical Centerline Discharge: Self-venting design for air handling, with casing providing maximum piping support.
• Replaceable Stuffing Box Bushing: Minimizes packing and sleeve maintenance.
• Extra Thick Wall Sections: For extended wear life.
• Dual Volute Casing: Provided on sizes as required to minimize radial unbalance.
• Renewable Sideplate: Heavy suction sideplate minimizes maintenance costs, positively sealed with O-ring and gasket.
• Lubrication Flexibility: Oil lubrication is standard; grease and oil mist are optional.
• Optional High Efficiency Finned Cooler: Requires minimum cooling water and is easily cleaned.
