• Inch-dimensioned OD of mechanical seal sleeve
• Inch-dimensioned bearing locknut
• Inch-dimensioned shaft and keyway at coupling

Operating Limits

• Capacities: to 45,000 GPM (10,220 m³/h)
• Heads: to 410 feet (125 m)
• Temperatures: to 446° F (230° C)
• Pressures: to 232 PSIG (16 bar)
• Average Bearing Temperature: 120° F (50° C)
• Bearing Design Life: >100,000 hours

Feed Water / Process Fluid

The Goulds 3180 is designed to handle tough process pumping applications, including:

• Paper stock
• Slurries and stringy fibers
• Recycle fibers with contaminants
• Severe corrosives
• Abrasive slurries
• High temperature liquids
• Hazardous fluids
• 6% paper stock (without flush water)

Specific applications mentioned include:

• Digester recirculation
• Make-up liquor
• White liquor
• Black liquor
• High pressure / high temperature pulp mill services
• Hot oil

Mechanical / Hydraulic

Key Features:

• Patented Intelligent Monitoring: Condition Monitor continuously measures vibration and temperature at the thrust bearing, with colored LEDs indicating pump health and providing early warning.
• Standard Labyrinth Oil Seals: Prevent premature bearing failure due to lubricant contamination and loss.
• Sealing Flexibility: Choice of mechanical seal, packed box, or dynamic seal.
• Patented TaperBore™ PLUS Seal Chamber: Designed to improve lubrication and heat removal for extended seal life and pump uptime.
• Casing: Top centerline discharge for air handling and self-venting, special volute design reduces radial loads, back pull-out design, foot-mounted.
• Renewable Suction Sideplate: With open impeller design to minimize maintenance costs, positively sealed with O-ring and gasket.
• Open Impeller: Features a full back shroud and thick vanes for handling slurries and stringy fibers. Large balance holes and back pump-out vanes minimize stuffing box pressure and axial thrust.
• Optional Impellers: Enclosed impeller and Shearpeller™ design (Patented Design #6,609,890) are available, with Shearpeller™ specifically for difficult recycle services to prevent clogging.
• Continuous High-Performance: Maintained by simple external impeller adjustment for long-term energy savings.
• Heavy-Duty Shaft: Designed for minimum deflection at maximum load, with a dry shaft achieved by O-ring sealing from pumpage.
• Rigid Feet: Large casing and bearing frame feet maintain driver alignment with high pipe loads and absorb system vibration.
• Clamped Sideplate: Ensures maximum reliability and zero leakage.
• Minimum Hydraulic Loads: Engineered open impeller design assures minimum radial and axial thrust loads to maximize seal and bearing life.
• Dynamic Seal Option: Allows pumping slurries without an external flush. A repeller pumps liquid from the stuffing box while running, and a diaphragm seal prevents leakage when stopped. This option eliminates external seal water, pumpage contamination/product dilution, and associated piping problems.
• Modular Interchangeability: Components such as casing, sideplate/impeller, stuffing box, and power end are designed for interchangeability across various pump sizes (L, M, S, XL, XL1, XL2, XL2-S Groups).

Hydraulic Coverage: Hydraulic coverage charts are provided for 50 Hz (capacities in m³/h, heads in meters) and 60 Hz (capacities in GPM, heads in feet) operations. See the official PDF for exact tabulated values and performance curves.

Dimensions: Dimensional drawings are included, with all dimensions in inches and (mm). These are not to be used for construction.
